The Trek X-Caliber 8 is a sure-footed 29er hardtail mountain bike, with plenty of reliable elements that boost its score to impressive levels, but a few missteps that hold it back from quite making it as one of the best hardtail mountain bikes we’ve tested. There’s a whole lot to like though.

Twenty nine inch wheels have long been an integral part of Trek’s mountain bikes, especially the hardtails. And where initially there was uncertainty and hesitation in the industry, Trek pushed on with this larger wheel size and the persistence paid off: with 29in wheels now accepted globally and across all mountain bike categories, not just for the cross country crowd.

Trek’s early 29in wheel bikes were XC hardtails and since then, the X-Caliber has shifted upmarket and now sit between the entry-level Marlin and the carbon Pro-Caliber. All three platforms run 100mm travel forks.

We’ve pulled in the X-Caliber 8 for this review, which is just shy of the Scott Scale 965 in price and shares many of the same components. With all four bikes on test running Shimano brakes and 1×12 transmissions, we were keen to take this consistency a step further and chose models with regular seatposts, rather than droppers. Primarily for comparing the weight of the bikes, but riding dynamics and overall value played a part too as we felt it really levelled the playing field, and maintained the XC hardtail design ethos.

With a steeply sloping top tube and a super-low standover height the X-Caliber is a very striking bike. It’s a silhouette that’s mirrored through all the brand’s hardtails – with the notable exception of the carbon Pro-Caliber – as is the wide size range that Trek is well known for offering. Seven frame sizes are available (with the XS and S rolling on 27.5in wheels to keep proportions in check) with a useful M/L option that’s a great problem solver for riders stuck between the popular M and L options. So hats off to Trek for this level of commitment to getting a good fitting bike.

When it comes to new frame standards, Trek has always been an early adopter, so it’s no surprise to see a tapered head tube and Boost hub spacing on the X-Caliber frame. But it’s Boost with a twist… here, Trek using 141mm rear dropout spacing with a traditional Q/R hub, rather than a 148mm bolt-thru design.

It’s not a deal breaker though, as the fixed rear triangle of a hardtail doesn’t need stiffening up like a full suspension design, and a quick online search reveals plenty of wheel upgrade options from the likes of Hunt, Hope and Bontrager for the 141 standard.

A modern touch that hasn’t been executed as well as on other bikes in test, is the internal frame routing for the cable and rear brake hose – they’re not clamped where they enter the down tube and rattle noisily on rough terrain, just like on the Trek Roscoe in our Hardtail of the Year test.

Trek has equipped the X-Caliber 8 with a RockShox fork and it’s listed as a Judy SL, so we expected to see an upgrade or two. However, all the tech is identical to the regular Judy forks seen on the Cube and Scott – a tapered aluminium steerer, steel upper legs, a Solo Air spring and the brand’s basic TurnKey damper.

The Trek is the only bike in test that doesn’t have a remote lockout lever though, just a simple dial on the top of the fork leg, with an on/off function and no graded adjustment between those points. At least it’s one less cable to maintain and gives more handlebar space for a dropper post remote lever.

And while the X-Caliber frame does not use a bolt-thru rear axle, the 100mm travel Judy fork does have the 15x110mm Boost hub standard – although the website lists the lighter tooled axle as standard, our test bike had the same QR lever operated version as the Scott Scale.

Shimano was slow to filter its 1×12 transmissions down to the lower price points, but it’s there now and proving to be a very popular choice, all four bikes in this test using Shimano drivetrains. The X-Caliber’s specification lists a Shimano chainset, but our bike shipped with a model from FSA, and it’s the only deviation from a complete Shimano drivetrain.

Trek has also gone with a smaller 30t chainring and combined with the Deore 10-51t cassette you get a super-low gear, which is useful on the climbs because at 13.53kg (29.82lb) the Trek is the heaviest bike in test.

Another wise move is the genuine Shimano chain which performs faultlessly in wet filthy conditions and plays well with the steel FSA chainring. The benchmark XT rear mech is good to see, as is the rubber chainstay protector, which is a detail the other three brands seemed to have overlooked.

Performance

The dropped top tube, wider 750mm bar, long wheelbase and slackish 68º head angle (the slackest of the four bikes) give the X-Caliber the look and feel of a trail bike. However, the Trek’s geometry and attitude is not in the same league as the most progressive 100mm trail hardtails such as Kona’s test-winning Mahuna .

Even on this size XL, the frame’s front triangle is very compact, especially when compared to the Giant XTC, but it still sports two sets of bottle cage mounts – essential on an XC bike. In fact, Trek has added plenty of mounts to the X-Caliber, with fittings for a rack and kickstand making it a very capable all-terrain bike.

With one of the lightest wheelsets on test, we expected some zip and liveliness from the X-Caliber but it lacked the immediate urgency of the Scott and Giant and on longer non-stop cross country blasts, its weight was noticeable, certainly towards the end of the ride.

You can’t knock the Trek’s sure-footed nature though – the lengthy wheelbase (for an XC hardtail) and wide bar aid stability, and it was only the Judy fork’s lack of refinement that held us back from diving into more challenging terrain. A slightly shorter stem would no doubt help here too.

Although the compact front end still has a tall 525mm seat tube, the seat stays are dropped, giving a tighter rear triangle. This certainly gives the X-Caliber a chuckable hardtail vibe, but the ride quality was a touch less compliant than the other bikes here.

With that in mind, there’s plenty of frame and fork clearance for higher volume tyres to help smooth the ride further, and Trek helpfully supplies the X-Caliber 8 with rim strips, valves and sealant so you can go tubeless straight from the box and reap the benefits immediately.

• Best hardtail mountain bikes
• Best mountain bike helmets: a bunch of brilliant brain-savers
• How to avoid arm pump when mountain biking

With a sure-footed ride, reliable Shimano components and a sorted tubeless wheelset, it feels like there’s a trail bike hiding under the X-Caliber’s glossy frame finish just waiting to get out, but being held back by the fork and lack of a dropper post. Stepping up a model to the X-Caliber 9 would be our recommendation then, as it gets a dropper post and a more capable and refined fork. Ultimately, the Trek X-Caliber 8’s weight is noticeable and even with the same control tyres fitted to all of the test bikes, the Trek lacks the race-bike urgency of the Scott and Giant.

Trek X-Caliber 8 review

Trail confidence without breaking the bank

David Rome / Immediate Media

In 2014, Trek's X-Caliber (Skye for women) was re-born as a range of entry-level 29er hardtails. Just a year on, it's undergoing further changes, thanks to what Trek calls ‘Smart Wheel Sizes’ – that means smaller 650b hoops for the two smallest frame sizes, and 29in ones for every other size.

Given our near perfect experience with last year’s X-Caliber 7 , the sight of a RockShox branded fork on the new immediately had us smiling – although a corresponding price rise also has to be factored in. So is the new model worth the extra outlay?

Ride and handling: pro-level trail character with superb balance

The handling qualities of the last year’s X-Caliber 7 were a major factor in the praise we showered on it. Borrowing the geometry from Trek’s popular and World Cup-proven Superfly range, the 29in wheeled 7 rides like a performance bike, rather than the entry-level model that it is.

While smaller frame sizes will undoubtedly experience some difference in handling owing to their 650b wheels, our 17.5in-framed test bike immediately – and reassuringly – felt similar to the X-Caliber 7.

Out on the trail, the ride from the X-caliber's geometry shines

The spacious top tube, short stem combination means your weight sits evenly between the wheels, making for balanced handling. Factor in the relatively short rear end and you've got a comfortable riding position with easy manoeuvrability when the terrain requires. Meanwhile the wide, well-swept Bontrager handlebar offers plenty of leverage for confident control of the bike.

The front derailleur cable is routed internally through the top tube for a clean look

Plenty of handlebar height adjustment is available

It’s worth noting that the X-Caliber's responsive handling and undeviating climbing ability is only fully unlocked once the stem is lowered from its stock position. The bike's short head tube and a large stack of headset spacers allow for plenty of handlebar height adjustment options.

Rolling freely and with authority, the 29er wheels and large volume rubber take charge on rock and root infested trails. Smaller rocks and ripples in the ground go past unnoticed, with the RockShox XC32 fork doing a decent job at absorbing bigger hits – though sharp square-edged bumps can overwhelm it.

Along with a crown-mounted lockout and coil spring preload, the XC32 fork offers rebound control – something that is missing from cheaper models.

The RockShox XC32 fork works well in most conditions, though some flex becomes evident when it's really pushed

Unlike pricier steeds, the X-Caliber sticks with a standard 1 1/8in steerer and quick release axle. But it's only when you really push it that flex is felt in the fork – for most trail conditions, and most riders, it’s a non-issue. (It’s certainly stiffer than the 2015 X-Caliber 7’s XC30 fork)

Trek has also done a respectable job in smoothing the X-Caliber’s ride quality. While little compliance is offered by the alloy frame or firm handlebar grips, large 2.2in tyres go a long way towards filtering trail buzz. Combine this with a generously padded saddle that sits atop a skinny 27.2mm seat post, and the ride is by no means harsh.

It's worth bearing in mind though that while the X-Caliber is capable and eager to go just about anywhere, it does so more slowly than a fancier machine will. Whether you're hauling in speed for a fast approaching corner, conquering the steepest hill in the area or pumping the bike into the air, you're regularly reminded of the weight compromises – especially where it's carried by the wheels – that must inevitably be made with entry-level bikes.

Frame and equipment: well rounded build that’s capable of real riding

As mentioned above, depending on your size the 2015 X-Caliber frame goes through significant changes, or none at all. In the case of our 29in sample it’s the latter, with one exception in the form of brighter paint.

The frame is a fairly no-nonsense build featuring wide tyre clearance, internal front derailleur cable routing, easily serviced threaded bottom bracket and cleanly guided full-length sealed cable housing. Showcasing the potential versatility of the X-Caliber for commuting or light touring, the frame features both fender and pannier rack mounts out the back.

A bit of additional weld at the rear brake mount is used to reinforce the frame. Although it isn't the prettiest...

The build quality is pretty great, however, our brake hoses arrived a little long and messy. Good bike mechanics will clean this up before it reaches your hands, but if not, don't accept giant unnecessary loops in the hoses.

A 2x10 gearing system isn't commonly seen at the X-Caliber 8's price. But is it a good thing?

Given that this is the model above the previously tested X-Caliber 7, it’s no surprise the components are better. Beyond the front fork, the drivetrain is the next most obvious point of upgrade, with this model featuring a SRAM 2X10 system, more commonly seen on higher-end bikes. With 10-speed at the back and just two chainrings on the front, the X-Caliber’s gearing has been optimised for off-road use.

As discussed in our mountain bike groupset buyer’s guide , SRAM is Shimano’s key competitor and a popular choice in mountain biking. The X5/X7 components are an approximate equivalent to Shimano Deore and once set up correctly offer crisp and reliable shifting. It's still not as fast as more expensive options, but it didn’t miss a beat while being tested.

Gearing wise, the small chain ring and largest cog on the cassette enable you to crawl up even the steepest of climbs without too much stress. On the reverse, the 36T big chaninring is well suited to fast off-road use, though it may prove under-gunned for those looking to put a skinnier tyre on and commute. For such usage, other brands that stick with a triple chainring setup may suit you best.

Quality components where it matters

Something we don’t often sing about on bikes at this price is tubeless tyres. A tubeless setup allows for lower tyre pressures without the risk of flatting, so providing a smoother ride quality and greater traction on the trail. Additional benefits include lower weight and reduced rolling resistance. While the X-Caliber isn’t set up tubeless, it does feature tubeless ready rims that proved nicely off-road worthy.

In order to ditch the tubes, you’ll still need to buy the appropriate rim strips, tubeless-ready tyres and sealant, but it’s the single biggest upgrade you can do to the bike (after decent pedals) and it’s not a huge expense either.

Although the supplied Bontrager tyres are durable and confident treads for many trail conditions, they carry plenty of weight. Upgrading to tubeless with a compatible tyre would see the bike drop half a kilogram (and probably more) in weight.

We're big fans of Shimano brakes – even the cheapest models

While SRAM takes care of the drivetrain, Shimano handles the braking duties. This is a common and popular choice, because Shimano's entry-level brakes set the benchmark with reliable function and solid performance. The basic model on the X-Caliber lacks the precise feel and bite of more expensive models, but newer riders will quickly gain complete confidence in the system.

So we’ve covered what you’re gaining over the cheaper X-Caliber 7 , but it's also worth considering what you get at the next pricepoint up.

In some countries (including the US and UK), the X-Caliber 9 is also available and provides an example of what to expect. It offers an air-sprung fork for greater suspension tuneability and substantial weight savings. Additionally, the drivetrain components see a further upgrade that should aid in long-term durability. Finally, the hubs move to a sealed bearing unit – effectively creating a lighter system that use replaceable cartridge bearings instead of the cup and cone loose ball-bearing system found on the X-Caliber 8 and below.

Common advice when buying a starter mountain bike is to spend as much as your budget allows. As we’ve seen in our testing of the X-Caliber 8, that advice rings true in the form of lower weight along with suspension, gearing and wheels that are better suited to the punishment meted out by off-road use. Whatever your budget, be sure to factor in the cost of pedals, as those included won’t let you see what this bike is capable of.

Trek X-Caliber 8: Everything You Need To Know

At a Glance: Features of the Trek X-Caliber 8

• Aluminum frame
• RockShox 30 Silver 100mm suspension fork and hardtail suspension system
• Shimano MT200 hydraulic disc brakes
• Shimano Deore front derailleur, Shimano Deore XT rear derailleur, and Shimano Deore 10-Speed shifters

Introduction

Are you going off-roading on rough trails or participating in cross country (XC) mountain biking?

There are many things you need to take care of when doing any of these activities. Before you get anything else done, however, you’ll have to start by choosing a reliable, high-quality bike.

Today, we’re going to check out what kind of companion the X-Caliber 8 from Trek Bikes is for your mountain biking trips.

Let’s get right into it and start with the complete guide on X-Caliber 8.

Our Guide to Trek X Caliber 8

Trek Biking Company has been making bikes since 1976. Across four decades, the company has built a reputation for crafting excellent, durable bikes that offer serious performance, regardless of your experience level.

The X-Caliber series from Trek Bikes takes this legacy forward with their XC mountain bikes. For the purposes of this review, we’ll be focusing on the X-Caliber 8 model only.

So, let’s get started with the features of Trek X-Caliber 8.

The X-Caliber series is a range of XC bikes all made of aluminum frames. These are lightweight bikes with a tapered head tube, and a rack and kickstand mount.

The internal cable routing helps to add to the neat appearance of these X-Caliber bikes.

X-Caliber 8 also features Boost 141 hub spacing that makes your frames stiffer and wheels stronger. It also gives you shorter chainstays, and more tire and chainring clearance. This allows you to ride on low-difficulty terrains with ease but isn’t suitable for particularly rough trails.

Like all XC mountain bikes, the X-Caliber also employs a lightweight geometry that gives you better pedaling efficiency.

The X-Caliber 8 is a hardtail bike, meaning that it does not have suspension in the back and the front suspension locks out. This makes biking on climbs and sprints easier.

The 1x SRAM drivetrain on this X-Caliber requires fewer gear adjustments which means a better biking experience for you with fewer chain drops. However, this configuration also offers fewer gear options.

If you’re looking for better flat-out speed, then a 2x or 3x drivetrain might be better for you.

The company has equipped the X-Caliber 8 with Shimano Deore front derailleur, Shimano Deore XT rear derailleur, and Shimano Deore 10-Speed shifters.

These speed shifters allow you to shift easily between riding positions with their 2-way release triggers.

The tire size will differ depending on the bike size you choose. Trek offers the following size options for its X-Caliber series:

• 29×2.4 inches for medium and large X-Caliber bikes
• 27.5×2.8 for small and extra small X-Caliber bikes

Versatility

Is the Trek X-Caliber 8 a versatile mountain bike?

The X-Caliber 8 is one of the most versatile bikes you’ll find on Trek’s list. The X-Caliber 8 allows you the freedom to go off-road or ride single-track marathons and races.

Can you take the X-Caliber 8 on long rides or touring? Absolutely!

The X-Caliber 8 is durable and will sustain you on long rides and touring as well. It is best suited for long trails with uphill and downhill riding.

Weight and Load Capacity

The medium-sized X-Caliber 8 weighs 28.77 pounds and its total load capacity is 300 pounds.

Braking System

Don’t forget about the braking systems!

This X-Caliber 8 mountain bike comes with the Shimano MT200 hydraulic disk brakes.

Hydraulic brakes are excellent for beginners because they do away with cables and also require less pressure. They are also lightweight so the bike’s overall weight is well adjusted.

But the Shimano MT200 brakes are the best for those looking to try MTB for the first time. These are quiet breaks that utilize one-way bleeding technology to prevent air from entering the hydraulic system.

What this means is your breaks and the hydraulic fluid in them will remain in optimum condition for years, without any need for regular bleeding and maintenance.

Want to add more flexibility to your seat’s height on those rocky terrains?

X-Caliber 8 is internal dropper compatible which allows you to upgrade your seat height limit whenever you want to.

At a rough price of $1,400, the X-Caliber is a cost-effective option among hardtail bikes which typically go up to $1,500.

Accessories

The bike features rack mounts that allow you to carry some accessories on those long trips you’ve been wanting to take.

Want to install accessories such as lights and computers on your bike?

Trek allows you to do that with its Blendr-compatible stem system.

Colors and Sizes Available

Trek makes its X-Caliber 8 in two different color options. One is a combination of lithium gray and trek black. While the other combines a radioactive red with trek black.

The X-Caliber 8 is available in a variety of size options from small and medium to large and double XL.

Trek X-Caliber 8

X-Caliber 8 is a cross country mountain bike made for fast laps and long days on the trail. It's built with special attention to value and the parts that make the biggest difference in performance. A 1x Shimano drivetrain, RockShox fork, and hydraulic disc brakes make it a great choice for new mountain bikers and XC racers searching for fast, fun, singletrack adventure. It's right for you if... You're looking for a fast mountain bike for singletrack—one that's fully capable of taking on races, marathons, and competitive group rides. You want something that is reliable and fun with dependable, lightweight parts. The tech you get A lightweight aluminum frame, a RockShox Judy SL 100mm suspension fork with a TurnKey lockout and an air spring that's lighter and more adjustable than a coil spring, tubeless ready wheels with Boost141 hub spacing, and a Shimano Deore 1x12 drivetrain with a wide-range cassette. The final word With X-Caliber 8, you're getting a performance frame paired with performance parts, like a RockShox air fork and 1x Shimano Deore drivetrain. Plus, it's equipped with durable, lightweight alloy rims that save weight and are easy to upgrade to tubeless. Why you'll love it - It has the price of a more basic hardtail, but the parts and performance of a more expensive one - The frame is fully compatible with higher-end parts, like race wheels and a dropper post, if you ever find the need to upgrade - Smart Wheel Sizing means you'll get the fastest wheel that fits (29" wheels on larger frames, 27.5" wheels on smaller frames) - The 1x drivetrain delivers a wide range of gearing with the simplicity of a single shifter Wheel size: - Sizes X-Small – Small: 27.5-inch - Sizes Medium – XX-Large: 29-inch
