Understanding Trek's naming system

Trek's naming system follows a similar style to how Canyon names its bikes. Each bike's name is suffixed with a number, with higher value numbers corresponding to pricier and better-kitted bikes. Once we get to 9, Trek adds decimals to the suffix to denote changes in the bike's suspension package. All bikes with a 9 in the name get carbon frames but a 9.7 might get its suspension from Fox's Rhythm range for example, while a 9.8 will get better something from higher in the range. Also, you'll see that a lot of kit on the bikes come from Bontrager, for the uninitiated that's Trek's in-house component brand.

At the '9' level, we also see XT, XO1, and GX finding their way into the names. Yep, you've guessed it, that's the drivetrain the bike comes kitted with.

Another thing that's definitely worth mentioning is that a small selection of Trek's bike range is available through what the brand calls Project One. Project One offers the opportunity to have your bike personalised and custom painted with special, exclusive colours. This will mean you have to part ways with a heap of cash but in return, you'll get a bike that's unique to you.

As with the brand's range of bikes, the price range is vast with bikes starting from £440, right up to £9,200 and that's not even considering the Project One options. There's also a comprehensive range of gravel bikes and e-bikes.

Let's kick things off with the Slash. It's Trek's enduro bike which rolls on 29" wheels and gets 160mm of travel at the rear, paired with 170mm at the front. For 2021 it gets both an aluminium and carbon frame option all of which benefit from Trek's proprietary Knock Block system which saves your top and down tube if your front end spins during a crash. This bike also gets the Mino Link which is a geometry adjusting flip-chip, down tube guards threaded bottom brackets, an Active Braking Pivot, and storage in the downtube. As for the geometry, in the low setting, the Slash sees a 75.6° effective seat tube angle, a 64.1° head tube angle, and a 435mm chainstay. A large frame gets a 486mm reach. If you're after something a little more special, the Slash is available through Project One.

Slash 9.9 XTR

Topping the Slash range is the Slash 9.9 XTR. It gets Trek's OCLV carbon frame with the all-new RockShox Super Deluxe Ultimate shock with an updated ThruShaft damper. At the front, you'll find the RockShox ZEB Ultimate RC2 which features chunky 38mm stanchions. As its name suggests there's a full Shimano XTR 12-speed drivetrain with an e*thirteen LG1 Race Carbon crank. The brakes here also come from the XTR lineup and they come with 4-pot calipers for extra stopping power. This bike rolls on a pair of Bontrager Line Pro 30 which are wrapped with a Bontrager SE5 Team Issue 2.6" Tubeless Ready, Core Strength sidewall, aramid bead tyre at the front and an SE5 Team Issue with the same spec in 2.4" at the rear. It also gets a Bontrager Line Elite Dropper with Bontrager supplying the 820mm wide carbon bar, 35mm stem along with the rest of the build kit.

Slash 9.9 XO1

The Slash 9.9 XO1 gets all of the same trimmings as the 9.9 XTR but benefits from a SRAM XO1 Eagle drivetrain and SRAM Code RSC Brakes, along with a slightly friendlier price tag.

Slash 9.8 GX

Shaving a few thousand pounds of the range-topper is the 9.8 GX. This one is still built around Trek's carbon frame but this one gets a slightly downgraded RockShox ZEB Select+ RC with a RockShox Super Deluxe Ultimate. Here we get a SRAM GX drivetrain with a matching crankset and SRAM Code R brakes. As for the rest of the bike, it's the same as the 9.9 XTR.

Slash 9.8 XT

As its name suggests, the Slash 9.8 XT gets a very similar built kit to the 9.8 GX. However, this bike sees a Shimano XT drivetrain with SLX M7120 four-piston brakes.

Dropping a full £1.8k off of the 9.8 models, the Slash 9.7 is still built around a carbon frame and it swaps the RockShox suspension with a Fox Rhythm 36 fork and a Fox Performance DPX2 EVOL shock. The drivetrain is a mix of SRAM GX and NX Eagle and the wheels here are the alloy Bontrager Line Comp 30's. Those come shod with a Bontrager XR5 Team Issue, Tubeless Ready, Inner Strength sidewall, aramid bead 2.6" tyre at the front with a Bontrager XR4 with the same spec and a 2.4" width at the rear. Trek has also swapped the dropper post for a TransX post and there's Bontrager's own alloy finishing kit.

With the Slash 8, we no longer get a carbon frame but we do get a RockShox Lyric Select+ RC fork with a RockShox Super Deluxe Ultimate at the rear. This bike is driven by a SRAM GX Eagle drivetrain and there's a pair of SRAM Code R brakes. Everything else is the same as what you would get on the 9.7 model.

The Slash 7 rounds of the range with its alloy frame, RockShox Yari RC fork, RockShox Deluxe Select+ shock, and SRAM NX drivetrain. Here we get a pair of SRAM Guide T brakes and the rest of the bike follows suit with the 8.

Trek Remedy

The Remedy is Trek's long-legged trail bike which comes with four models for 2021. It rolls on 650b wheels and gets 160mm of travel at the front, with 150mm at the rear. Much like the Slash, the Remedy benefits from the Knock Block, the Active Braking Pivot, and the Mino Link. Geometry-wise, it gets a 65.6° head angle, a 74.2° effective seat tube angle, and 435mm chainstays in the low position. A large frame gets a 455mm reach, again in that low setting.

The Remedy 9.8 is the only bike in the 2021 line up that gets a carbon frame. It also gets a burly Fox Performance 38 paired with a Fox Performance Float DPX2 EVOL shock at the rear. This bike benefits from a SRAM GX Eagle drivetrain matched with SRAM Code R brakes. As for the wheels, they're a pair of carbon Bontrager Line Elite 30's and they're wrapped with a Bontrager SE5 Team Issue, Tubeless Ready, Core Strength sidewalls with an aramid bead in 2.6" with a Bontrager SE4 Team Issue with the same specs in the 2.4" width. Bontrager also supplies the dropper post with the Line Elite and the 820mm handlebar along with the 35mm stem.

As suggested by the lack of a '9' in its name, the Slash 8 comes kitted with an alloy frame. As for the fork, it's a RockShox Lyrik Select+ RC and that's paired with a RockShox Super Deluxe Select+ shock. This bike is also driven by a SRAM GX Eagle drivetrain and it gets the same brakes as the 9.8 rig. Differing from the range-topper, this build sees in a pair of Bontrager Line Comp 30 alloy wheels which get an XR5 Team Issue tyre that's tubeless-ready with Inner Strength sidewalls and an aramid bead in 2.6", also from Bontrager. At the rear, there's an XR4 with the very same specification. The rest of the bike follows suit with the 9.8 model.

Remedy 8 XT

Rather unsurprisingly, the Remedy 8 XT comes with a very similar build to the 8 but gets an XT drivetrain and Deore M6120 four-pot brakes. Everything else on this build matches the Remedy 8.

The Remedy 7 is the cheapest 2021 Remedy on offer. It gets a RockShox Gold RL fork and a RockShox Deluxe Select+ shock. There's a SRAM NX drivetrain with SRAM Guide T brakes. Apart from that, everything else is the same as what you'll get on the Remedy 8's.

Trek Fuel EX

The Fuel EX is Trek's do it all trail bike. It gets 130mm of rear travel and 140mm at the front. Just like the Slash, the Fuel EX gets built-in downtube storage and the Active Braking Pivot. It comes with a RE:aktiv shock with Thru Shaft, something that you'll only find on Trek bikes. It promises more grip and control with a shock the reacts to the ground faster than anything else on the market, says Trek. This bike also gets the Mino Link, Knock Block, and Straight Shot downtube. The Fuel EX comes in five sizes with XS getting 650b hoops and M upwards getting 29" wheels. However, size S comes with a choice of either wheel size. As for the geometry in the low setting, the bike gets a 66° head angle, a 75° effective seat tube angle, and a 437mm chain stay. A large frame benefits from a 470mm reach.

Fuel EX 9.9 AXS

Topping the range with a pretty hefty pricetag is the 9.9 AXS. On this model, you'll get a Fox Factory 36 with a GRIP 2 damper, paired with a Fox Factory Float EVOL RE:aktiv shock. Of course, we then get wireless shifting from SRAM and the AXS range along with a wireless RockShox Reverb AXS dropper. It rolls on a pair of Bontrager Line 30 carbon wheels and they're wrapped with two Bontrager XR4 Team Issue tyres with Inner Strength sidewalls and aramid beads, measuring in with a 2.6" width at the front and a 2.4" at the rear. Bontrager supplies the finishing kit with a Knock Block stem and a 780mm OCLV carbon handlebar.

Fuel EX 9.9 XTR & XO1

Next up, the Fuel EX 9.9 XTR gets all of the bling. It's built around Trek's OCLV carbon frame and gets a Fox Factory 36 fork with a GRIP2 damper. At the back, there's a Fox Factory Float EVOL, RE:aktiv. As its name hints, this bike comes with a Shimano XTR 12-speed drivetrain with matching XTR M9120 four-piston brakes. There's also an option with a SRAM XO1 drivetrain with SRAM G2 RSC brakes. This one rolls on a pair of Bontrager Line Pro 30 OCLV carbon wheels which are wrapped in a pair of Bontrager XR4 Team Issue, Tubeless Ready tyres with the brand's Inner Strength sidewalls and aramid bead. At the front, there's a 2.6" tyre with a 2.4" at the rear on both wheel sizes. Then the bike comes kitted with a Bontrager Line Elite Dropper and the rest of the kit comes from the same brand.

Fuel EX 9.8 XT & GX

Offering a saving of over £2,000 over the top of the range bike is the 9.8 GX and XT. This bike comes with the same carbon frame as the most expensive bike but sees a downgrade in suspension and drivetrain. Here we get a Fox Performance 36 with a GRIP damper and a Fox Performance Float EVOL, RE:aktiv shock. This rig comes with a choice of drivetrain with either SRAM's GX groupset or Shimano's XT. The GX build comes with SRAM G2 RS brakes whereas the XT model is stopped with a pair of Shimano SLX M7120 four-piston brakes. Everything else on these builds is the same as what you'll find on the 9.9 XTR model.

Fuel EX 9.7

The 9.7 is Trek's most affordable carbon-framed Fuel EX. It comes kitted with a Fox Rhythm 36 with a GRIP damper and a Fox Performance Float EVOL shock. The drivetrain here is a mix of SRAM NX and GX with the former making up the shifter and the latter handing the mech. Gone are the carbon wheels, unfortunately, but instead we get a set of Bontrager Line Comp 30 wheels wrapped in the very same tyres like the rest of the range. The rest of the bike follows suit with the pricier models but there's an alloy bar and stem.

Fuel EX 8 XT & GX

At the sub £3k mark Trek does away with the carbon frames and replaces them with cheaper alloy alternatives. On the priciest alloy option, we get a Fox Rythm 34 Float with a GRIP damper and a Fox Performance Float EVOL RE:aktiv shock. On this build, there's a choice of either a SRAM GX Eagle drivetrain or a Shimano XT with the former benefitting from SRAM G2 R brakes and the latter receiving a pair of Shimano MT4100 levers mated to MT420 four-piston callipers. This bike gets a pair of Bontrager Line Comp 30 alloy wheels and the rest of the build is the same as what you'll get on the 9.7 bike.

Fuel EX 7 NX

On the Fuel EX 7 NX we find a RockShox 35 Gold RL fork and a Fox Performance Float EVOL shock, note that this shock doesn't come with that special RE:aktiv tech. You've guessed it, this one comes equipped with a SRAM NX Eagle drivetrain it gets its brakes from Shimano with a pair of MT4100 levers and MT410 callipers. The rest of the bike, including the wheels and tyres on this bike, is the same as the rest of the alloy range but we see a TransX dropper on this model.

Fuel EX 5 Deore

Rounding off the fairly extensive range is the reasonably priced Fuel EX Deore. It gets a RockShox Recon Silver fork with an X-Fusion Pro 2 shock. Then there's the Shimano Deore 12-speed drivetrain with Shimano brakes made up of MT201 levers and MT200 callipers. The wheels see a downgrade from the rest of the range with an Alex MD35 rim laced to Bontrager hubs. They're wrapped in a pair of Bontrager XR4 tyres and there's a TransX dropper post. The rest of the finishing kit comes from Bontrager.

Trek Top Fuel

Like it or not, but down-country bikes are becoming more and more prolific. Luckily for those who are on board with the trend Trek has a bike for you. It comes kitted with 120mm travel up front and 115mm at the rear with 29" wheels. In keeping with the rest of Trek's bikes so far the Top Fuel also gets a Straight Shot downtube and Trek's Active Braking Pivot. It's also kitted with the Mino Link and Control Freak cable management system. Moving onto the geometry, the Top Fuel sees a 68° head tube angle, a 75.7° effective seat tube angle and a 434mm chainstay. A large frame gets a 470mm reach and those numbers have been taken with the bike in its low setting. As for frame sizes, there's a choice from XS right up to XXL.

Top Fuel 9.9 XX1 AXS

A few hundred pounds shy of the 10k mark, this bike comes with all of the top tech. It's made around a carbon frame with a RockShox SID Ultimate fork with a Race Day Charger damper and a RockShox SID Luxe Ultimate shock. There's a RockShox TwistLoc Full Sprint lockout remote too. As for the drivetrain, here we get a SRAM XX1 Eagle AXS 12-speed wireless set up with SRAM G2 Ultimate brakes. The wheels on this bike area pair of Bontrager Kovee Pro 30 Carbon hoops and they're kitted with a pair of Bontrager XR3 Team Issue, Tubeless Ready tyres with Inner Strength sidewalls and aramid beads in a 2.4" width. Finally, there's a RockShox Reverb AXS wireless dropper post, Bontrager OCLV carbon bar with a 750mm width and 35mm clamp and a Bontrager stem.

Top Fuel 9.9 XTR & XO1

Next up, the Top Fuel XTR and XO1 models get the same carbon frame but this time there's a Fox Factory 34 Step Cast with a FIT4 damper paired with a Fox Factory Float shock. This bike also gets the RockShox Twistloc remote lockout. With this model, there's a choice of either a SRAM XO1 drivetrain or the Shimano XTR set up. The XO1 model gets SRAM G2 RSC four-piston brakes while the XTR gets XTR M9100 brakes. Everything else on the bike is the same as the AXS model but the dropper, which is a Bontrager Line Elite.

Top Fuel 9.8 XT & GX

The Top Fuel 9.8 sees a saving of £2.4k and gets its suspension from RockShox with the SID Select+ RL fork and RockShox SID Ultimate RL shock. There's a choice of drivetrain on this bike too between either a SRAM GX Eagle 12-speed with SRAM G2 RSC brakes or a Shimano XT drivetrain with SLX M7000 brakes. Everything else on this bike is the same as its pricier brethren.

Top Fuel 9.7

The 9.7 model is the cheapest with a carbon frame and it comes with a RockShox Reba RL fork and a Fox Performance Float DPS shock. There's a SRAM NX Eagle 12-speed drivetrain with Shimano brakes consisting of MT501 levers and MT500 calipers. This bike makes a move to Bontrager Kovee Comp 23 alloy wheels and they get the same tyres as the rest of the range. We get an alloy cockpit and a Bontrager Line Dropper.

Top Fuel 8 NX

At this price point, Trek introduces alloy frames into the mix. With the 8 NX there's a RockShox Recon Gold RL Solo Air with a Fox Performance Float DPS. There's still a remote lockout here but it comes from Bontrager in the form of the Drop Lock. As its name suggests, this bike is driven by a SRAM NX drivetrain and it's stopped with a pair of SRAM Level T brakes. The rest of the bike is the same as what you'll find on the 9.7 model.

Top Fuel 7 SX

The Top Fuel 7 SX is the most affordable bike in the range featuring suspension from RockShox with the Judy SL Solo Air fork and the X-Fusion Pro 2 shock. There's a SRAM SX Eagle 12-speed drivetrain with Shimano MT200 brakes. This one rolls on the same alloy wheels as the rest of the range with the same tyres. In fact, apart from the TransX dropper post, everything else matches the Top Fuel 8 NX.

Trek Full Stache

While the Full Stache hasn't had an update for 2021, it seems rude not to include it as there aren't an awful lot of full suspension 29+ bikes on the market. Of course, it rolls on 29" wheels with chunky 3" tyres. It also has 130mm of travel at both ends but the frame is compatible with up to a 140mm fork if you fancy some extra lairy riding. There's also the Mino Link, Control Freak cable management and the Knock Block. It's built around an aluminium frame and gets a 67° head tube angle, a 75.5° effective seat tube and a 430mm chainstay in the low setting. A large gets a 480mm reach, again in the low setting.

Full Stache 8

With its aluminium frame, you'll find a RockShox Pike Select Plus RC fork with a Fox Performance Float EVOL RE:aktiv shock. There's a SRAM GX Eagle 12-speed drivetrain, aTruvativ Descendant 6k crank and SRAM Guide R brakes. This bike gets a pair of SUNringlé Duroc 40 SL wheels and they're shod with a pair of Bontrager XR4 Team Issue, Tubeless Ready tyres with Inner Strength sidewalls and aramid beads. We get a Bontrager Line Dropper on this bike with a 780mm wide alloy bar, also from Bontrager.

Trek Supercaliber

Filling the role of the full suspension cross country bike is the rather unique looking Supercaliber. The standout feature of this bike is its IsoStrut suspension platform. It offers 60mm of fully tunable travel and what makes it special is that it does away with a rocker link thus saving a chunk of weight. The IsoStrut is also a structural feature of the frame which Trek says prevents twisting, flex and deflection which the brand claims offers a more direct power transfer. The whole range of Supercalibers feature carbon frames rolling on 29" hoops, Straight Shot downtube and the Knock Block. The geometry on this bike sees a 69° head angle, 74° seat tube angle and a 430mm chainstay. The reach of a large frame measures in at 455mm. There are six sizes from S to XXL and an ML size which gets a longer top tube than the M. Up front there's 100mm of travel.

Supercaliber 9.9 XX1 AXS

The Supercaliber 9.9 XX1 AXS takes the crown as Trek's most expensive mountain bike. It comes dripping with top-shelf kit such as the RockShox SID SL Ultimate with a Charger Race Day damper and a Fox Factory IsoStrut shock. This bike gets SRAMs XX1 Eagle AXS wireless drivetrain with the carbon crank and SRAM Level Ultimate brakes. It rolls on a pair of Bontrager Kovee XXX OCLV carbon wheels and they're wrapped with a set of 2.2" Bontrager XR2 Team Issue, tubeless ready tyres with Inner Strength Sidewalls and aramid beads. Then the finishing kit also comes from Bontrager and the line of carbon components, including a 720mm wide handlebar.

Supercaliber XX1 & XTR

Next up the Supercaliber 9.9 XX1 and XTR get all of the same kit as the priciest model but they drop the fancy wireless shifting. Instead, there's a choice of either a SRAM XX1 Eagle drivetrain with SRAM Level Ultimate brakes or a Shimano XTR drivetrain with XTR M9100 brakes.

Supercaliber XT & GX

Seeing a considerable saving from the rest of the range, the Supercaliber 9.8 GX and XT models get a downgraded Fox Performance 32 Step-Cast fork with a GRIP2 damper. There's also that IsoStrut suspension also provided by Fox but this model doesn't get that sleek Kashima coating, coming from the brands Performance line-up. These models come with a choice of either a SRAM GX Eagle 12-speed groupset with both choices coming kitted with Shimano Deore XT M8100 brakes. Here we get a pair of Bontrager Kovee Pro 30 carbon wheels, then the rest of the kit is the same as what you would get on the other bikes.

Supercaliber 9.7

The Supercaliber 9.7 is the most budget-friendly option in the range. It's still built around that OCLV carbon frame and the Performance level IsoStrut shock but gets a RockShox Reba RL fork. This one is driven by a SRAM NX Eagle drivetrain and it's stopped by brakes from Shimano with the MT501 levers and MT500 calipers. This model gets slightly narrower Bontrager Kovee Elite 23 carbon wheels with the same XR2 tyres but the rest of the bike comes from Bontrager's alloy line of kit.

Trek Procaliber

The Procaliber is Trek's lightweight cross country hardtail. Compared to the Supercaliber it presents a mighty cash saving if you're looking for a race-ready XC bike. That doesn't mean that it's not without some cool tech, however. The Supercaliber benefits from what Trek calls the IsoSpeed decoupler which allows the set tube to rotate independently from the top tube to seatstay junction which Trek says offers some vertical compliance without sacrificing pedalling efficiency. As with the rest of the range, this bike gets the Straight Shot downtube and Knock Block too. Each bike in the Supercaliber line up comes with a carbon frame which rolls on 29" wheels and can fit up to 2.4" rubber. Here we see a 68.8° head angle, a 73.8° seat tube angle and 432mm a chainstay. A large frame benefits from a 450mm reach and there are six sizes, from S up to XL, including an ML size which gets a longer top tube than the M. The Procaliber gets 100mm of suspension.

Procaliber 9.8

Built around an OCLV carbon frame the Procaliber 9.8 comes with a Fox Performance 32 Step-Cast fork with a GRIP damper. It's driven by a Shimano XT drivetrain with Deore XT M8100 brakes but this one gets an e*thirteen TRS Race Carbon crank. The wheels here are a pair of Bontrager Kovee Elite 30 carbon wheels and there's a pair of Bontrager 2.2" XR2 Team Issue, tubeless-ready tyres with Inner Strength sidewalls and aramid beads. The rest of the kit comes from Bontrager too, with a 720mm wide carbon handlebar.

Procaliber 9.7

This model comes equipped with a RockShox Reba RL Solo Air and a SRAM GX Eagle 12-speed drivetrain with Shimano MT501 brake levers hosed to MT500 calipers. This bike gets Bontrager's Kovee Elite 23 wheels, then the rest of the bike matches the 9.8 model.

Procaliber 9.6

On the 9.6 model of the Procaliber you'll get a RockShox Recon Gold RL and a mixture of Shimano kit making up the drivetrain. There's an SLX M7100 shifter and an XT M8100 derailleur. With this model there's the move over to alloy wheels, they come from Bontrager and the Kovee's. Then there are the same tyres as the rest of the range and an all-alloy finishing kit from Bontrager.

Procaliber 9.5

Finally the Procaliber line-up is rounded off with the 9.5. Even as the cheapest bike, it still gets that OCLV carbon frame but sees a RockShox Judy SL fork. There's a full Shimano Deore 12-speed drivetrain with Shimano MT200 brakes. Then the rest of the bike features the same kit that you'll find on the 9.6 model.

Trek X-Caliber

If you're looking for a race-ready cross country bike but you're on a budget, the X-Caliber is the bike for you. Accommodating for its affordable price point is an aluminium frame rather than the carbon you'll find on its pricier sibling, the Procaliber. The X-Caliber comes kitted with rack mounts, so it's bike-packing ready, along with a mount for a kickstand. All frames feature internal routing and they all come kitted with Trek's Blendr stem. The X-Caliber comes with either 650b wheels on sizes XS and S with all larger bikes (up to XXL) roll on 29" hoops. As for the geometry, there's a 73° effective seat tube angle on sizes M and up while the smaller two sizes get a 73.5° effective seat tube angle. Then there's a 69.5° head tube angle (S and XSs get a 69.3° HA) and a 438mm chainstay on M and up, and a 425mm chainstay on the smaller bikes. Sizes S to XL get 100mm of travel leaving XS with just 80mm. Although, the frame will accept a maximum of a 120mm fork while the XS can accept a 100mm fork.

X-Caliber 9

Heading up the range, the X-Caliber 9 gets a RockShox Judy Silver Solo Air with a TurnKey remote lockout. This bike gets a Shimano SLX M7100 12-speed drivetrain with Shimano brakes made up of an MT401 lever and an MT400 caliper. The wheels on this one are a pair of Bontrager Kovees and they're wrapped with a pair of Bontrager XR3s in the 2.3" width on all sizes. The finishing kit comes from Bontrager too with an alloy bar, stem, and seat post.

X-Caliber 8

The middle of the range X-Caliber 8 comes with a RockShox Judy SL Solo Air fork with a SRAM SX Eagle 12-speed drivetrain. Stopping the bike is a pair of MT200 brakes from Shimano. As for the wheels, the rims come from Bontrager with a pair of kovees and they're laced to Formula DCL-141Q hubs. Then the rest of the bike is the same as the X-Caliber 9.

X-Caliber 7

The X-Caliber 7 gets much of the same kit as the X-Caliber 8 with the only difference in spec being its Shimano Deore 10-speed drivetrain.

Trek Roscoe

If you're looking for a trail orientated hardtail, the Roscoe fits the bill. Each build comes properly sorted with dropper posts, 120mm of travel (size S gets 100mm), 1x drivetrains and alloy frames. The bike also rolls on 650b+ wheels and tyres. They all feature internal cable routing, rack and kickstand mounts too. Onto the geometry, the Roscoe sees a 67.3° head angle, a 70.8° effective seat tube angle (with the medium frame getting a 70.7° effective seat angle and the S and XS getting 71.2° and 71.1° angles respectively), and a large frame gets a 428mm reach. As a 650b+ bike, it can run either 27.5x2.8" or 29x2.4" rubber.

On the Roscoe 8, you'll find a RockShox 35 Gold RL fork with a SRAM NX Eagle 12-speed drivetrain with Shimano brakes in the form of the MT501 lever paired with an MT500 caliper. It's worth noting that the fork comes with a flexy QR axle. The wheels here are made of rims from Bontrager and the Line 40s with a Bontrager hub at the front and a Formula hub at the rear. This bike gets a pair of Maxxis Rekon tubeless tyres with a 2.8" width and then the rest of the kit comes from Bontrager and the alloy range apart from the dropper post, which comes from TranzX with the JD-YSP18.

The Roscoe 7 benefits from most of the same kit as the 8, but this one gets a SRAM SX Eagle 12-speed drivetrain and Shimano MT200 brakes.

On the cheapest Roscoe 6 you'll get an SR Suntour XCM 32 coil sprung fork with a Shimano Deore 10-speed drivetrain and MT200 brakes. This bike then rolls on Alex MD35 rims and Formula DC hubs which get a pair of Kenda Havok, wire beaded, 2.8" tyres. As for the rest of the build, that's just the same as the rest of the range.

Trek Marlin

If a sub £1k cross country, everyday bike is more your speed then it's worth checking out the Trek Marlin. Each bike in the range comes with an alloy frame and a fork with 100mm of travel (XS frames get 80mm). There are also rack and stand mounts, the Blendr stem, and internal cable routing. XS and S sizes roll on 650b wheels while sizes M to XXL get 29" hoops. On the Marlin, you'll get an effective seat tube angle of 73.5° on the XS and S frame while everything else benefits from a 71.9° effective seat tube angle. As for the head angle, on the smaller sizes it'll measure in at 69.3° and from M upwards it's a couple of degrees steeper at 69.5°. All frame sizes share a 438mm chainstay length and a large frame gets a 451mm reach.

The Marlin 7 comes kitted with a RockShox Judy coil sprung fork with a Shimano Deore 10-speed drivetrain and Shimano MT200 disc brakes. The wheels are made of Bontrager Kovee rims laced to Formula DC hubs and they're wrapped with a pair of Bontrager XR2 Comp 2.2" tyres with wire beads. The rest of the bike comes with Bontrager's own finishing kit.

Trek Farley

Perhaps fat bikes are more your things. Allow me to introduce the Farley. There are two in the 2021 range with an alloy and a carbon option which, of course, roll on 4.5" tyres. Both bikes come with a dropper post, horizontal sliding dropouts, ideal for single speed setups and tubeless-ready tyres. As for the geometry, the Farley gets a 69° head angle, a 73° effective seat tube angle and a 455mm chainstay. The reach on a large is 441mm and there are four sizes available, from S to XL. 

The Farley 9.6 gets an OCLV carbon frame with a Bontrager Haru OCLV fork. The drivetrain on this bike comes from SRAM and the GX Eagle 12-speed shifting. As for wheels, they're Sunringle Mulefut 80 SL rims laced to Bontrager alloy hubs. Those are wrapped in a pair of Bontrager Barbegazi Team Issue, tubeless-ready tyres with inner strength sidewalls and aramid beads. The dropper kitted here is a TransX JD-YSP18 and the rest of the kit comes from Bontrager with a 750mm wide bar.

The Farley 5 is Trek's best value fat bike and it's built around an alloy frame. It gets a Shimano Deore M4100 10-speed drivetrain with SRAM Level brakes and there's a Race Face crank. It gets the same wheels as the 9.6 but the tyres here are a pair of Bontrager Gnarwhals. The rest of the kit is the same as the 9.6. It's worth mentioning that while the Farley 5 comes with a rigid fork, it'll happily accommodate a 100mm travel suspension fork.

Trek Session

The Session needs no introduction, but it's the brand's 650b downhill bike. There's only one model in the 2021 range which is built around an alloy frame. It gets Trek's Active Braking Pivot and the geometry adjusting Mino-Link. Up front, there's 200mm of travel and at the rear, there's 210mm. In the low setting, the Session gets a 63.6° head angle, a 445mm chainstay and a large frame gets a 426mm reach. There are four sizes, from S to XL and the 8 27.5 model will set you back £4,200

Trek Ticket

Finally, rounding off the Trek range of mountain bike is the Ticket. It's available as the full suspension, Ticket S (pictured) with 100mm of travel and the Ticket DJ, which is the hardtail version. Both come as a frame only with prices starting from £725, up to £1,400.

Get to know your Remedy from your Fuel

We have a look over the 2018 range of Trek mountain bikes to see who suits what in a range featuring the Fuel EX, Remedy, Marlin and Powerfly models.

>>> All our recent Trek mountain bike reviews

Getting to grips with 2018 Trek mountain bikes

If you pop over to Trek’s website and click on ‘mountain bikes’ more than 120 bikes appear in front of you. It’s rather daunting. Choice is good but can be bewildering. So we’ve boiled Trek’s MTB range down to the basics to get you started.

>>> Trek road bikes: which model is right for you?

What type of bike do you want?

We think it’s best to split the whole range into three categories and then go from there: hardtail , full suspension and electric .

What type of riding will you be doing?

Once you’ve chosen one of the three categories you can refine it to the type of riding you want to do: cross-country, trail or downhill.

With those two category types chosen you’ll be left with a much smaller pool of Trek models to consider.

We’re going to assume that you already know the type of mountain bike you want. We’re not going to go into any debates or theorising (hardtail vs full suspension, 27.5 vs 29 , Plus vs Fat etc etc).

Trek hardtails

There are five hardtail models in Trek’s range: Marlin, X-Caliber, Roscoe, Procaliber and Stache.

Trek use their own proprietary frame materials. Their aluminium stuff is called Alpha. Their carbon stuff is called OCLV.

Some of their high end hardtails have the ‘IsoSpeed Decoupler’ configuration where the seat tube is designed to flex for compliance.

The Trek Marlin is an entry level cross-country focussed hardtail ranging from £370 up to £550. Thee are four models in total (the Marlin 4, 5, 6 and 7). The frame is Trek’s ‘Silver Alpha’ aluminium.

The Trek X-Caliber cross-country range starts from £650 and tops out at £1,150. The frame is Trek’s ‘Gold Alpha’ aluminium. The frames have internal routing for stealth dropper seatposts. The components are of a higher quality than the Marlins.

The Trek Roscoe range of Plus-tyred trail hardtails running from £800 to £ 1,250. The frame has internal routing for dropper posts and is made from Trek’s ‘Alpha Gold’ aluminium.

The £1,300 to £6,500(!) Trek Procaliber cross-country race bike range can look a a bit confusing; there are aluminium Procalibers, OCLV carbon Procalibers and Super Light OCLV Procalibers. Although the frame material varies the intent of Procalibers is the same: xc racing. The geometry remains the same. All Procalibers have the ‘IsoSpeed Decoupler’ feature of deliberate flex.

The Trek Stache bikes are rather unique in that they are 29er Plus bikes. They roll on some seriously large rubber! Monster trucking hardtails. Price: £1,300 to £3,500.

Trek full suspension bikes

There are five Trek full susser types: Fuel EX, Remedy, Top Fuel, Slash and Session.

All Trek full sus bikes use a version of the ‘ABP’ suspension design. ABP stands for Active Braking Pivot. The rear wheel axle is also the rear pivot. The idea is to prevent the suspension from locking up during rear braking.

Fuel EX, Remedy and Top Fuel bikes also have RE:aktiv rear shock damping. This damping design claims to ‘know’ which forces are coming from the pedals/rider and which forces are coming from the trail, and it reacts accordingly.

The Trek Fuel EX 130mm travel, full sus, all-rounder, trail bikes come as either 29er or as 27.5 Plus. They can be run with either wheel size but are initially purchased with one or the other. Starting from £1,800 for aluminium versions they top out at £6,500 for the top end carbon version.

>>> Trek Fuel EX Plus 9.8 27.5 (2017) review

The Trek Remedy is the 150mm travel trail-cum-enduro bike. Prices range from £2,300 to £6,000. There are aluminium Remedy models and carbon fibre Remedy models. For 2018 they are all 27.5in wheel.

The Trek Top Fuel bikes are full suspension XC race machines. 100mm of travel at either end. Begins with the aluminium Top Fuel 8 for £2,400 and goes up to the £7,800 carbon Top Fuel 9.9 RSL.

>>> Trek Top Fuel 9 (2017) review

2018 Trek Slash

The 160mm travel enduro racing Trek Slash range is all 29in wheels and carbon only for 2018. It’s a bold move by Trek but one that makes the Slash arguably the most defined model in their range.

>>> Trek Slash 9.9 29 RSL (2017) review

The Trek Session is the downhill bike. Aluminium or carbon. And now available as a frameset as a 29er with 190mm of travel. Complete build Sessions are all 27.5in wheel and deliver 210mm of rear travel.

Trek electric mountain bikes

There are three electric mountain bike types: Powerfly, Powerfly FS and Powerfly LT Plus.

The Trek Powerfly hardtails start at £2,300 and go up to £3,300. Aluminium frames with 100mm travel forks up front. The motors come from Bosch. There is also a £4,200 Powerfly Plus with 2.8in tyres.

On the Trek Powerfly FS bikes the ‘FS’ stands for Full Suspension, 130mm of suspension to be precise. The Powerfly FS bikes are aimed at cross-country riding with a bit of rougher stuff every now and then. All but the entry level £3,500 Powerfly 5 FS come with Plus tyres.

Trek Powerfly Launch in Verbier, Switzerland

The Trek Powerfly LT Plus models have more travel (150mm) and fatter tyres (2.8in Plus tyres). These e-bikes are up for a bit more aggro riding and technical trails. Prices: £4,200 to £5,250.

Trek Women’s mountain bikes

Even as stalwarts of the whole Women’s Specific Design thang, Trek (along with most other bike brands) are now seemingly moving away from design theories that assume that women’s body proportions are different to men’s.

Bikes fit humans, not genders. Rider height is the only thing you should really be factoring in when choosing a bike. It really is only saddles that need to be a bit different to men’s.

It’s fine to opt for a supposedly ‘men’s’ Trek model if it fits your height. Get the saddle swapped out for a ladies saddle at time of purchase. Sorted.

Having said that, if you want a Women’s bike because you prefer the different colourway and decals, fair enough.

• Trek Skye – entry level cross-country hardtails
• Trek X-Caliber Women’s –  lighter and fancier cross-country hardtails
• Trek Roscoe Women’s – Plus tyred trail hardtail
• Trek Procaliber Women’s – XC racing hardtail
• Trek Fuel EX Women’s – 130mm travel full suspension all-rounder
• Trek Remedy Women’s – 150mm trail/enduro full susser
• Trek Powerfly Women’s – entry level e-bike hardtail
• Top Fuel Women’s – XC racing 100mm travel full suspension

Race Shop Limited models

You may spot some Trek mountain bikes with ‘Race Shop Limited’ (or ‘RSL’) in their model name. These are essentially super high spec models. Often limited edition. And sometimes with slightly tweaked designs (a bit more travel, slacker geometry etc etc).

Mark Webber’s Top Fuel Project One

Trek’s Project One

This is Trek’s custom paint and decals option. Yep, if you have the funds and are prepared to wait a bit for your bike, then you can get a Trek in pretty much any colour scheme you want.

Be warned: you can waste hours (days!) tinklering away with the online Project One dream bike builder.

It’s only available on a few mountain bike models: Top Fuel, Fuel EX and Procaliber.

Wil reviews the Trek Fuel EX 2023

Having undergone a ground-up redesign for 2023, the Trek Fuel EX has entered its burliest and biggest travel form yet. This latest model represents the 6th generation of Trek’s popular mid-travel trail bike, with the original having debuted all the way back in 2005. Trail riding has evolved a lot since then, and the new Fuel EX aims to keep up with that evolution by incorporating almost every mod-con you can think of.

Of course it’s big news whenever Trek releases a new Fuel EX, and given how important this bike is for the US brand, we were curious to see how the raft of updates would play out on the trail. We had a bit of an idea, having thoroughly enjoyed riding the electrified Trek Fuel EXe over the past few months. Would the muscle-powered version deliver the same good vibes? And how would it compare to the previous models that have given us so many fond riding memories over the years? We’ve been putting the Trek Fuel EX 2023 to the test to find out!

Watch our video review of the Trek Fuel EX 2023:

Along with the downtube storage, generous frame armour and size-specific chainstays, the Fuel EX appears to pack in almost everything you could possibly want in a modern trail bike.

An overview of the Trek Fuel EX 2023

For 2023, the Trek Fuel EX is built around an entirely new frame that’s produced in carbon and alloy variants. Suspension travel has increased by 10mm at both ends, with the new Fuel EX now sporting a 150mm fork and 140mm of rear travel via the ABP four-bar suspension design.

It’s worth noting that the frame will handle a 160mm travel fork, and thanks to the two-position Mino Link, it can also be run as a mullet. Borrowed from the Session downhill bike, there’s a two-position flip chip at the lower shock mount that offers linear and progressive settings. The latter option is what makes the new Fuel EX coil shock compatible.

On top of that, Trek will be offering aftermarket headset cups to steepen or slacken the head angle by a degree. Along with the downtube storage, generous frame armour and size-specific chainstays, the Fuel EX appears to pack in almost everything you could possibly want in a modern trail bike. It’s certainly an appealing package on paper, and one that’s ready to take on contemporaries like the Specialized Stumpjumper , Merida One-Forty , Canyon Spectral and Giant Trance X .

Trek Fuel EX price & specs

There are a number of different models available in the Trek Fuel EX 2023 lineup, though availability will vary depending on where you are in the world.

In Australia, prices currently range from $4,999 AUD for the Fuel EX 7, and go up to $8,999 AUD for the Fuel EX 9.8 XT model. The cheapest option is actually the Fuel EX 5, though that model carries over the previous generation frame. For a closer look at the specs, prices and all the new details, check out our Trek Fuel EX 2023 overview article for more.

Here we’ll be diving into our experience of testing the Trek Fuel EX 9.9 XX1 AXS model, which will be available in Australia in limited quantities through the custom Project One bike builder. It’s a media bike that was provided to us by Trek, and of course it comes dripping with lots of gold, carbon and wireless bits. However, as usual with our reviews, we won’t be going into detail about the Gucci-level spec. Instead, we’ll be concentrating on the important aspects that are shared throughout the Fuel EX lineup; the frame design, suspension performance and its on-trail handling.

• RRP |  $TBC

The chassis feels near-bombproof, and combined with the supportive suspension, powerful brakes and high volume rubber, you’re served up plenty of confidence for pushing the front wheel into steep chutes and over technical A-lines.

Trek Fuel EX size & geometry

From X-Small through to XX-Large, the Trek Fuel EX is produced in no fewer than seven different sizes. Seven! Given that many brands only offer four or sometimes even just three frame sizes, that’s impressive.

The two smallest sizes feature 27.5in wheels, while the Medium and above come standard with 29in wheels. The Small is the only option that is available in either wheelsize.

At 175cm tall I’ve been riding a Medium, which features a 450mm reach. Thanks to the use of short seat tubes, a rider of my height could easily upsize to the M/L size to get a longer 470mm reach. Personally, I’ve found the fit of the Medium to be spot-on.

As for geometry, the Fuel EX features a 64.5° head angle and approximately a 77.5° effective seat tube angle in its stock configuration. The rear centre length varies between sizes, going up to 450mm on the largest frame. On the Medium I’ve been riding, the rear centre is a compact 435mm.

Coming off the Fuel EXe, I found it easy to settle into the Fuel EX. The only modification I needed to perform was to chop the comically wide handlebars from 820mm down to a more reasonable 780mm.

Suspension & tyre setup

Getting the Fuel EX set up is made easy thanks to Trek’s detailed online suspension calculator . Input the bike model and your riding weight, and out spits suggested air pressure and rebound settings for both the fork and shock. It even suggests tyre pressures, giving you a good place to start before hitting the trail. When brands like Canyon struggle to provide any recommendations at all, Trek should be commended for helping riders to get the most out of their bike.

For my 68kg riding weight, Trek suggests setting up the Fox 36 fork slightly softer and slower than usual. Recommended rear shock sag is 29%, and the calculator’s suggestion of 158psi got me to exactly that figure. Initially I set the rebound at 6/15 clicks as recommended, but while everything felt quite balanced front to back, the suspension was a little sluggish and duller than I wanted. Speeding up the rebound by a couple of clicks in both the fork and shock helped to make the whole bike feel a bit more lively, while improving small-bump reactivity.

Although the Bontrager SE5 tyres feature reinforced Core Strength casings, I still fitted a CushCore Pro insert to provide some additional pinch-flat protection and insurance for the carbon rims. Tyre pressures were set as per Trek’s recommendations with 20psi in the front and 22psi in the rear.

Trek Fuel EX weight

Confirmed weight for our Trek Fuel EX test bike is 14.4kg. That’s with the tyres set up tubeless, but without the CushCore insert or pedals.

It’s on the heavier side for a high-end carbon trail bike, though the 2.5in tyres, stocky carbon wheels and AXS components aren’t exactly the lightest going. Of course weights do vary throughout the Fuel EX lineup depending on the spec, and you can see the weights for all the different models in our range overview .

A contributing factor to the overall weight is the new frame, which has gained almost 700g over its predecessor. Trek claims the carbon frame weighs 3.4kg with the rear shock, making it a bit of a porker alongside some of the competition;

• Scott Genius HMX Carbon: 2,249g
• Specialized Stumpjumper Carbon: 2,280g
• Giant Trance X Advanced Pro 29: 2,498g
• Specialized Stumpjumper EVO Carbon: 2,750g
• Canyon Spectral CF: 3,047g
• Trek Fuel EX Carbon: 3,400g

The new alloy Fuel EX frame is heavier again, coming in at a hefty 4.6kg with shock.

Of course weight isn’t everything, and it’s unsurprising that the new frame has gotten heavier given how much longer and slacker it is. Still, for those who are especially concerned by grams, there are certainly lighter options on the market.

What do we dig about the Trek Fuel EX 2023?

With its added heft and updated geometry, the Trek Fuel EX 2023 is no doubt the burliest iteration yet. The chassis feels near-bombproof, and combined with the supportive suspension, powerful brakes and high volume rubber, you’re served up plenty of confidence for pushing the front wheel into steep chutes and over technical A-lines.

Indeed it’s massively capable for a 140mm travel bike, with the slack 64.5° head angle and roomy wheelbase giving it a purposeful stance on the trail. The geometry is superb, with welcome updates that have brought the Fuel EX right up to speed.

The steeper seat angle is particularly noticeable over the old bike, providing a much improved seated position on steep climbs. Pedalling efficiency has also levelled up. Trek has lifted the main pivot above the chainring to increase anti-squat, which helps to reduce pedal-induced bobbing. The Float X shock has a two-position climb switch, but I never once needed to use it while riding off-road since the rear end is so well behaved.

It rips through the turns

Once up to speed on flower singletrack, the taut chassis means the Trek Fuel EX is highly responsive when rounding corners and pushing into berms.

With its boxy downtube, split top tube and the supporting strut for the lower shock mount, the front triangle is heavily braced to resist torsional flex. Along with the wide main pivot and boxy one-piece chainstays, the Fuel EX possesses a strong spine from its shapely head tube to the rear thru-axle. The muscly frame effectively translates handling inputs while resisting lateral deflection through the turns.

Likewise, the short rear end and generous 38mm BB drop are fantastic when threading your way through twisty sections of trail, keeping you connected to the terrain and contributing to the playful ride quality. The low-hanging BB did mean I caught the pedals occasionally, so those who frequent off-piste terrain and technical climbs will want to consider flipping the Mino Link into the High position to indulge in an extra 7mm of pedal clearance.

Otherwise the riding position and weight distribution are totally sorted. The handling is approachable, and the Fuel EX doesn’t demand a whole lot from you as the rider. Compared to the old bike it does need a more concerted lean when entering tighter corners, though this is a part of the natural evolution of modern trail bike geometry. Even if you’re coming off a 5-year old bike, you’ll only need a few rides to get accustomed to the Fuel EX’s steering behaviour.

Trail-tweakable

In addition to the Mino Link, we’ve also been experimenting with the lower shock flip chip on the Trek Fuel EX. Requiring just a single 6mm hex key, it’s a quick adjustment to make trailside, and the change in suspension behaviour is noticeable.

I ended up preferring the ‘Less’ setting, which provides a more linear leverage rate. With the shock set at the recommended sag, this position provides great pedalling support, along with more comfort and activity deeper into the stroke. There’s still a good deal of progression though. Combined with the large bottom-out bumper in the Float X shock, hitting full travel proved to be a well-controlled affair.

One of our fellow testers, who generally spends more time in the air than on the ground, preferred riding in the ‘More’ setting. This increases progression, providing a stronger ramp-up in the latter half of the travel. He also reduced the shock pressure by 5psi to further enhance small-bump compliance, while still being able to enjoy the additional big-hit support. Pedal efficiency isn’t as stable in this setting, but it does mean the Fuel EX takes to jumps like a duck to water, popping off lips enthusiastically and absorbing hard landings with a solid and flex-free touchdown.

One thing to note on the More/Less flip chip is that while you are altering the progression of the air spring, you’re also affecting the damper too. As well as adjusting air pressure, we found we needed to tweak the rebound and low-speed compression settings between the two positions. It is indeed a useful tuning tool, but it doesn’t dispel the need for air volume spacers entirely.

What does it struggle with?

With the Trek Fuel EX adopting a beefier frame, the added weight is noticeable compared to lighter bikes in this category. That’s compounded by the heavy-duty brakes, stocky wheels and chunky tyres, which mean there’s more inertia to overcome during micro-accelerations on an undulating climb.

For those who are looking for a sharper and sprightlier trail bike to whip through the trees along smoother singletrack, the latest Trek Top Fuel will be a better fit. In comparison, the new Fuel EX is a burlier beast that thrives on steeper and more technical terrain.

Curiously, it does feel stiffer than the electrified version, the Fuel EXe . Despite both our test bikes featuring carbon frames with a near-identical build kit, I’ve found the Fuel EX to transmit more trail feedback.

Some of this may be due to structural differences, and perhaps the more favourable sprung-to-unsprung mass ratio on the electric version thanks to the added weight of the motor and and battery. Either way, the Fuel EX doesn’t exactly exude off-camber compliance. As a lighter rider on very rocky terrain, I’ve found myself getting knocked around a little more than I would like.

This sensation reminded me of the Canyon Spectral 125 , which proved to be overly stiff and quite uncomfortable at slower riding speeds. The Fuel EX is more compliant overall than the Spectral 125, but it’s still pretty stiff.

It’s not as supple as Fuel EX models gone by

Contributing to this sensation, the suspension isn’t as plush as previous Fuel EX models, particularly those that featured the Thru Shaft shock. Those bikes did require the rider to make use of the compression lever to provide pedalling support, but it meant that in the open mode the rear end absorbed the terrain like melted butter.

You may have noticed that Trek has been making a conscious move away from proprietary suspension components lately, and that’s coincided with building bikes that offer more neutral pedalling performance. The increased anti-squat is one part of the equation on the new Fuel EX, and the other part is the custom-tuned Float X, which Trek has configured with a digressive compression tune on the main piston. This creates a decent low-speed threshold, which provides a level of support that sits between the Open and Medium settings on the previous RE:aktiv damper.

The result is that you can ride with the shock fully open, and the Fuel EX still offers great stability under pedalling inputs, with no real need to activate the climb switch. If you detest remote lockouts and having to flip shock levers all the time, this will certainly be appealing.

The downside is that the suspension isn’t as supple over smaller rubble and at slower speeds. Along with the stiff chassis and carbon wheels, more of those vibrations are transmitted to the rider. As such, careful consideration with tyre pressure is needed to maximise grip and comfort.

Because there is more support however, the Fuel EX gives your feet a stronger platform to push off of, with greater feedback during high-load scenarios. Indeed the harder and faster you push, the better the Fuel EX responds. In that sense, it’s less of a comfy cruiser like its predecessors, and more of a mid-travel bruiser that loves to ride hard and fast.

Component highs & lows

As a complete bike, the Trek Fuel EX is a solid package that puts the emphasis on capability over light weight.

The Bontrager SE5 tyres are a good example, coming in at 1,100g each on our workshop scales. They roll reasonably well given their weight and size, and we’ve found them to provide consistent grip on rocky, hard-packed soil, which will suit most Aussie trail riders. The tread is a little shallow though, and the compound isn’t the softest, which sees them struggling to latch on when the conditions are wet and loose. We’d prefer something a little stickier and toothier up front, like a Maxxis Minion DHR II with 3C MaxxGrip rubber.

While the carbon Bontrager Line Pro rims are quite stiff, they have proven to be plenty tough. We’ve tested five of these wheelsets across various bikes over the past few years and we’ve not encountered a single issue. The y also come with a two-year crash replacement guarantee, which is great insurance given the hell that you can put this bike through. Furthermore, the frame itself comes with a lifetime warranty for the original owner.

There’s still plenty of real-world protection though, including a generous two-piece armour plate that bolts to the underside of the downtube. There’s also a metal chain-suck guard behind the chainring, and a full-coverage chainstay protector. Along with the fully guided internal cable routing, the Fuel EX is an impressively quiet and rattle-free bike on the trail. Well, except for the rear thru-axle lever, which I removed after the first ride.

Otherwise the finishing details are all sound. The adoption of a bigger 34.9mm seat tube diameter is welcome, as it accommodates a stiffer and stronger dropper post, particularly for the larger sizes. Mechanics will be happy to see a threaded BB shell, and we’re fans of the downtube storage. The trap door has none of the play that we encountered on the last Fuel EX we tested, with a tight fit and a nice lever action.

It’s certainly a high quality chassis, and many riders are likely to appreciate the in-built versatility. We’re looking forward to trying out the adjustable head angle once the aftermarket cups become available, and we’d also be keen to try out the Fuel EX with a coil shock. Setting it up as a mullet will be more straightforward, especially as you only need to buy an air spring to extend the Fox 36 up to 160mm of travel.

Trek Fuel EX vs Specialized Stumpjumper

Alongside the Trek Fuel EX, the Specialized Stumpjumper is one of the most popular and well-known trail bikes in this category. In terms of travel and the overall build, the Fuel EX sits right in between the regular Stumpjumper and the Stumpjumper EVO. However, it’s the regular Stumpy that I’ve been spending the most time on lately, both in its stock configuration and with a burlier mullet setup .

Compared to the Fuel EX, the Stumpjumper has a touch less travel with a 140mm fork and 130mm at the rear. It also uses a simpler suspension layout, with the carbon models employing a flex-stay design. Combined with its slimmer tube profiles, the carbon Stumpjumper frame is very light. Specialized claims it weighs just 2.28kg including the shock, which is over a kilo lighter than a carbon Fuel EX.

This theme extends to the Stumpjumper’s build kit, with Specialized electing for the skinnier Fox 34 over the 36. Along with an in-line shock, lighter brakes, wheels and tyres, there’s a considerable difference in the overall bike weight. For example, the Stumpjumper Pro we tested weighed 12.84kg.

While the geometry is pretty similar between the two bikes, the Specialized Stumpjumper rides much lighter on the trail compared to the Trek Fuel EX. It offers more comfort, with its lithe chassis and smooth suspension performance providing better compliance over rough terrain. It’s quite sporty and sprightly, though its active suspension design does need taming on the climbs by making use of the rear shock’s compression lever.

In comparison, the Fuel EX is more naturally efficient. It’s also more planted at speed, with its sturdy chassis and supportive suspension providing better big-hit capability. It feels more like a short travel enduro bike, which will suit heavier and harder riders.

Both bikes will handle a longer fork and can be set up as a mullet, though Specialized makes a specific link for the Stumpjumper to maintain the stock geometry. There is greater versatility in the Fuel EX chassis, with the option to adjust the head angle and fit a coil shock.

As for value, the Fuel EX offers a more appealing spec package. A Stumpjumper Expert sells for $9,800 AUD and comes with a Fox 34 GRIP2 fork, SRAM G2 brakes, an X01 drivetrain, alloy wheels and handlebars. In comparison, an equivalent Fuel EX 9.8 XT sells for $800 AUD less. It gets a simpler GRIP damper for its Fox 36 fork, though it does feature a piggyback shock, a Shimano XT groupset, a carbon one-piece RSL cockpit and carbon wheels with that 2-year crash replacement guarantee.

Flow’s Verdict

For many trail riders, the Trek Fuel EX 2023 is likely to tick just about every box on your new bike wish list. It’s as up to date as it gets, featuring loads of adjustability, internal storage and a nuanced approach to its size-specific geometry. Along with the increased travel and muscly frame, it offers greater stability and big-hit control over its predecessor, while still being a fun and involving bike to ride on modern flow trails.

It is a bit of a chonker though, so those who are looking for a lightweight and speedy trail bike may be better served by the latest Top Fuel .

The stiff chassis and supportive suspension also mean the Fuel EX tends to transmit more feedback, making it less comfortable to ride over rocky terrain. We’d be curious to try out a lighter shock tune to see how much of a difference that would make to the overall ride quality, but in its stock form the Fuel EX isn’t as plush as competitors like the Giant Trance X and Specialized Stumpjumper .

It is impressively efficient though, and the stable suspension gives you a load of support when you’re really giving it the beans on the descents. In this sense, the Fuel EX is closer in feel and performance to an enduro bike. You’ll still want to look towards the Slash if you’re serious about racing, but outside of the tape the Fuel EX will handle just about everything a modern trail centre or bikepark could throw at it. And for those who really want to up the limits, the adaptable chassis can easily be configured for some pretty aggressive riding.

Indeed for those who are chasing maximum capability without going to a big, spongy enduro bike, the Fuel EX is a mighty appealing option.

Pinkbike's 2022 Mountain Bike of the Year

"This is a bike that could be used to head out for a big meandering backcountry adventure one day, roll up to the starting line in a local enduro race the next, or even head into the bike park for a lap or three without missing a beat."

Editor's Choice: Best Mid-Travel Trail Bike

"The burliest, most versatile, and most capable Fuel yet; truly up for whatever you want to ride [...] The updated geometry sits comfortably amongst today's best trail bikes [...] Absolutely shreds right out of the box."

Trek Fuel EX 9.7 review

The name suggests XC DNA, but this is a thoroughbred trail bike and one of our Trail Bike of the Year contenders

Dan Milner / BikeRadar

A solid feeling frame backed up by a ride quality that encourages you to pop and play around

The long Shimano brake levers kill the feel, while the supple rear suspension shows up the budget fork

The Fuel EX is Trek’s 130mm travel trail bike and uses its ABP suspension linkage and proprietary Re:aktiv suspension tune.

This 9.7 model is made from OCLV carbon, but alloy versions of the Fuel EX are also available. It’s a 29er, with high-volume 2.6in wide tyres and benefits from a 140mm fork up front.

Trek is able to draw on its in-house componentry brand Bontrager for the bulk of the kit, so it’s a little surprising that in the value stakes, the Fuel EX 9.7 doesn’t shine. However, previous generations of the bike were popular at BikeRadar , and the Fuel EX has seen an update for 2020 .

Bike of the Year 2020

The Trek Fuel EX 9.7 is part of our annual Bike of the Year test.

Head to our Bike of the Year hub for the full list of winners, categories and shortlisted bikes, as well as the latest reviews – or read our behind-the-scenes feature on how we tested Bike of the Year 2020 .

Trek Fuel EX 9.7 frame and suspension details

Trek has been using carbon for decades, and its OCLV Mountain Carbon is the material of choice for the Fuel EX 9.7.

Unlike many brands, the tubes are largely straight – both the top and down tube feature barely a curve. This does mean that the down tube could be prone to fork-crown strikes in a crash, were it not for the Knock Block system built in to the headset.

This is a keyed frame/spacer/stem system, which limits the rotation of the fork during a crash. The frame comes with the pre-requisite down tube protection, as well as chainstay protection. Cables are routed internally, with clamped stops.

Seen on carbon Specializeds for a while, Trek also has its own down tube storage solution, located under the bottle cage.

While my test bike featured 29in wheels, the XS is available with 27.5in wheels only, while the S is offered in both wheel sizes, so you can choose depending on your preferences.

Trek’s ABP (Active Braking Pivot) linkage sits somewhere between a classic linkage actuated single pivot and a four-bar linkage, with a solid chainstay and seatstay, joined by a pivot located around the rear axle.

Trek has worked with Penske suspension for a number of years, developing the Re:aktiv suspension tune for its shocks.

This reacts to the shock’s shaft speed as it moves: faster shaft speeds mean the compression circuit opens up more during impacts, while slower shaft speeds (generally generated via pedalling) lead to a more closed-off circuit for better pedalling performance.

Trek Fuel EX 9.7 geometry

This latest generation Fuel EX benefits from a tweak to its shape, with a longer geometry that looks more contemporary on paper.

Trek uses its Mino Link chip in the suspension’s rocker link to give two geometry positions : High and Low.

For the bulk of the testing (and in the geometry chart below) I kept the bike in the Low position, which is around 0.5 degrees slacker than the High position, and a margin shorter too because of how geometry adjustment chips work.

Key figures in a Large are the 470mm reach, a 66-degree head angle and a 75-degree seat angle.

• Seat angle: 75 degrees
• Head angle: 66 degrees
• Chainstay: 43.7cm / 17.2in
• Seat tube length: 45cm / 17.72in
• Top tube (effective): 63.4cm / 24.96in
• Head tube length: 10.5cm / 4.13in
• Bottom bracket height: 33.9cm / 13.35in
• Wheelbase: 1,211mm / 47.68in
• Standover: 74.8cm / 29.45in
• Stack: 61.3cm / 24.13in
• Reach: 47cm / 18.5in

Trek Fuel EX 9.7 specifications

What’s clear from the spec list is that you’re paying for the frame with this bike.

It’s not a super glamorous specification, though none of the components are inherently poor – they all work together and give you the features you’d want from such a bike.

However, if you compared the components with some others in the Trail Bike of the Year test , you may come away a little disappointed.

If I bought the bike, I would look to swap out the brakes and the rear cassette. The brakes have a long lever that flexes and the NX level cassette is very heavy – although I'm not too worried about the 11-50t (rather than usual 10-50t) range it offers.

However, you should look beyond spec lists because how the bike rides is the most important thing.

It’s also worth noting that Trek bikes are generally sold through bike shops, which adds costs (or removes value), but comes with its own benefits. Arguably, you get better pre- and post-purchase support, as well as the ability to support local businesses on your high street.

Trek Fuel EX 9.7 ride impressions

Our 2020 Bike of the Year testing predominantly took place in the South West of the UK during winter. This included loops around trail centres, natural muddy and rooty tracks dug in to Welsh hillsides, as well as laps at BikePark Wales.

A number of bikes were taken to Spain for the final stage of testing, where we rode on dry, rocky flow trails, super-technical rock gardens and some loamy enduro tracks. Thanks to BlackTown Trails for their help finding these test tracks!

Setting up the Fuel EX 9.7 was fairly easy. The Fox shock and fork needed simple inflation and rebound setup, and the dropper worked from the off.

The only thing to bear in mind is that the larger the tyre volume, the more important tyre pressure is, and smaller changes in pressure make more noticeable differences in feel than a more ‘normal’ 2.35/2.4in tyre.

Trek Fuel EX 9.7 climbing performance

Bontrager’s XR4 tyres might have a large volume that ‘looks’ chunky, but I found them fast rolling thanks to their tread, which doesn’t protrude too far from the carcass.

This helps give the bike a little zing when pedalling on smooth surfaces, such as fire roads and tarmac.

Wider tyres generally allow slightly lower pressures, which can help on more technical climbs too, but I was limited a little on tyre pressure by the rims that could do with being a touch wider.

Over loose or muddy surfaces, the low-depth tread doesn’t have masses of bite, so I did slip out a few times on the greasier climbs. This was played out again on some technical climbs where you want a little bite from the tyre to help claw up steps and over roots.

The back-end sits fairly high, helping a peppy climbing attitude that's aided by the RE:aktiv shock, which reacts to shaft velocity to give a more stable shock under pedalling loads.

This meant I rarely reached for the shock’s lockout lever. It doesn’t replace a lockout, as such, but does mean a more efficient ride a lot of the time.

While the seat tube angle isn’t the steepest out there, I felt it was steep enough to get the hips reasonably well over the cranks. With the bike sitting higher in its travel than some, and remaining propped up on steeper pitches, I didn’t find it too compromising.

The longer front-end means there’s more room to manoeuvre over the bike on technical sections, too.

Trek Fuel EX 9.7 descending performance

The 130mm of rear travel uses Trek’s ABP suspension system, with the rear pivot rotating round the axle.

The suspension has a definite element of pop and support to it, contributing to a fun ride quality that really shined on tight and twisty woodland trails, as well as when shredding round our local bike park.

More aggressive or heavier riders will want a volume spacer or two in there though, because on bigger hits I occasionally found the end of the travel fairly quickly.

Trek has dropped the full-floating shock from the previous generation that was super-smooth in feel, but this generation bike feels a little more composed and less mushy through the pedals.

That previous generation bike was one of the smoothest we’ve ridden, and fortunately this generation bike still offers buttery smoothness from the rear suspension.

At the front, I found the smooth rear accentuated the cheaper 140mm travel Fox Rhythm 34 fork internals, which couldn’t match the rear’s sensitive feel.

Like the shock, a volume spacer would also aid the fork’s performance for larger or more aggressive riders.

Despite this, the fork still feels good for an ‘entry’-level fork; it’s fairly smooth, support could be a lot worse, and you get a compression dial on the fork leg to lock it out should you wish to on smoother climbs.

At 140mm travel, the Fox 34 chassis is at its limit in terms of structural stiffness. When riding moderately aggressive – in the bigger compressions round corners or punching through rock gardens – I could feel the fork fluttering and twisting, which is something to consider if you’re the type of rider that puts a lot of strain through forks.

The Fuel EX loves to chop and change direction, and with the back-end encouraging more than a little air-time thanks to its support, it’s a great bike to pop and play around trail centres.

Here, the large volume Bontrager XR4 tyres roll fast, adding to the bike’s sense of speed. It’s the same story on dry, flowy natural trails too, but when conditions get sloppy, they lack bite, as I found on the climbs.

On steeper terrain, or when ploughing through rocks, I found the Line Comp 30 wheelset’s rims didn’t quite offer the support that the tyres needed, leading to either a pingy ride when pressures were increased or a little squirmy when pushed hard into a catch-berm. This added to a sense of vagueness accentuated by the fork in the worst cases.

A mixed SRAM NX/GX drivetrain shifted well during testing, but didn’t mate well on the bars with the Shimano MT420 brake levers.

They have a long lever, which flexed while hauling on the brakes, detracting from the feel of the four-piston calipers.

Trek Fuel EX 9.7 bottom line

Trek's Fuel EX always finds favour with testers, so long as it’s kept within its comfort zone. Trek hasn’t built a mini-enduro bike here – that’s clear to see with the Fox 34 fork and faster-rolling tyres – so it’s unfair to judge it based on its performance on the chunkier trails.

That said, the rear suspension is more composed than the previous generation Fuel EX and the geometry is more suited to going fast. A sturdier fork and more precise tyres could make this a mini-monster of a bike, though.

If you’re looking for a ‘proper’ trail bike, one for zipping round trail centres, popping off rocks and roots, crossing plenty of ground relatively efficiently and generally just having a laugh on, then you may well love the Fuel EX as much as I do.

This model might not be the best value, but there’s an alloy version for a few hundred quid less that looks equally tidy.

With thanks to...

BikeRadar would like to thank 661 , IXS , Leatt , Garmin , Facom and BlackTown Trails for their support during our Bike of the Year test.

2019 Fuel Ex 9.7 vs Fuel Ex 8 or Remedy 8

• Add to quote

Coming from a 2014 Fuel Ex 8 29er I am looking to upgrade to a 2019 bike. I was looking at the Remedy 8 thinking the extra travel would be nice plus a change to 27.5 would be an interesting change. However if I'm honest, for the type of riding I typically do, the Remedy is much more bike than I need so I'm probably better off sticking with the Fuel Ex. Now the 2019 alloy Fuel Ex 8 hits the sweet spot for me in terms of price and specs but the only problem is my LBS has sold out of the Fuel Ex8 in my size (17.5). I don't want to downgrade to the 7 so the next best option is the 9.7. I've never been especially fussed about getting a carbon frame but I'm not opposed to the idea either. I just didn't think the extra cost was worthwhile. However as the 8 is sold out I'm now considering the 9.7. The specs look pretty good and similar to the 8 although possibly a slight downgrade in drivetrain. Tbh I'm not really familiar with the new specs, especially SRAM, as I haven't really kept up with the changes since buying my 2014 Fuel. Just wanting to get opinions on the 9.7 vs the 8. Should I get the 9.7 or would I be better off to just wait for the 2020 Fuel Ex 8? Bearing in mind the 9.7 is currently on sale (20%) being the end of line for the 2019 range (as is the Remedy) whereas the 2020 Ex8 will be full MRRP when it eventually comes in. Appreciate any opinions and/or recommendations?  

The 2020 Fuel EX will be out in the next few months. I'd wait for sure...  

If you’re set on a fuel ex, I’d definitely wait for the 2020. If you’re going to keep your 2014 fuel, you might want to demo a remedy. I rode one last month, and was blown away how much fun it was.

So no love for the Fuel ex 9.7 then?  

I looked at both the EX9.7 and the EX8+ this spring. Ended up buying the EX8+. The EX8+ has a littler better component spec. and a little more suspension up front. Also looked up the frames and the difference in weight was only 2lbs. I just couldn’t justify the extra cost. The first few times I rode it felt kind of slow but very comfortable. I’ve since set it up tubeless and swapped the tires out to WTB Ranger 2.8’s. Ended up knocking a full minute of my best time on the local trail. Eventuality I may buy a set of 29er wheels, but so far I am extremely happy with it. Sent from my iPad using Tapatalk  

If you are used to the 29er, I'd stick with that. I've ridden both and prefer the 29er for it's better rolling over the rough and higher/faster speed going downhill. The latest Fuel EX is about equal with the 2014 Remedy. I'd look for a newer/used 2018/2019 Fuel EX. Great deals on lightly used bikes are around to the to find if you search. Big savings this way, too. Otherwise, I'd wait for the 2020 Fuel EX. Rumor is that it will be a lil' changed over the current '17/'18/'19 design.  

Yeah I'm kicking myself, could've had the Fuel ex 8 at a 30% discount but I hummed and hawed over the Remedy and the Ex 8's sold out. Ah well I'll wait and see what the 2020 model brings to the table.
