When it was first released, the Emonda was a climber’s dream that Trek claimed as the world’s lightest production offering. Dealer events would have the ultra-premium 4.6 kg (10.25 lb) SLR 10 hanging from large helium balloons, and the American company made a big deal of it providing a benchmark stiffness-to-weight ratio. 

In many ways the Emonda back-filled the void left by the once round-tubed and low-weight Madone that was then becoming more aero. And as the Madone further trended to becoming Trek’s full aero racer (with an obvious element of comfort, too), the Emonda kept to its round tubes and stiff hill-attacking personality.  

That changed for 2021 with Trek overhauling the Emonda in a similar way to how almost every other brand has overhauled its lightweight race machine. The Emonda, now disc-only, gained a little weight by moving to slippery truncated airfoil tubes and a wholly new approach to cable routing in an effort to make it sleeker all-around. Additionally it should run quieter with a new threaded bottom bracket format, too. 

All of those techy details (and more) were covered in James Huang’s review of the top-tier Emonda SLR . And while James went pretty deep with that review, he left a few unanswered questions in relation to the more affordable 2021 Emonda SL. And so it’s exactly this more-affordable, second-tier version – specifically the Shimano Ultegra-equipped Emonda SL 6 Pro – that we took to our Field Test in Victoria’s High Country .

Emonda SLR vs Emonda SL

Story highlights.

What: A second-tier version of Trek’s all-round lightweight race bike. ||Key updates: Aero frame design, a more performance-oriented geometry, sleek semi-concealed cable routing, T47 threaded bottom bracket||Weight: 8.01 kg for the Emonda SL 6 Pro as tested (54 cm, without pedals), claimed frame weight is 1,142 g (56 cm).  ||Price: US$3,800 / AU$5,500 / £3,350 / €3,880-4,000||Highs: Obviously a race bike with geometry to match, agile handling, high-end looks, more tyre clearance than claimed, threaded bottom bracket, Shimano Ultegra is hard to fault, great saddle. ||Lows: Stiff ride quality, weight penalty in frame versus premium option, heavy carbon wheels, bend of handlebar is too tight.

There’s no denying that the Emonda SL (starting from US$2,700 / AU$4,000 / £2,275 / €2,580-2,600) is substantially cheaper than the pro-level SLR (starting from US$6,700 / AU$9,300 / £5,450 / €6,200), but what are you giving up in the process? Simply, it’s a matter of weight. 

An unpainted 56 cm Emonda SLR frame has a claimed weight of 698 g, while the matching fork adds 365 g. By comparison, the Emonda SL frame sits at 1,142 g, with the fork at 380 g. This 450-gram difference is simply attributed to the carbon composite layup used (in Trek marketing speak, that’s OCLV 800 vs OCLV 500), and simply less material is needed when the more expensive fibres and resins are stiffer and stronger.

That 1,142 g figure for the Emonda SL isn’t terribly heavy, but it is noticeably plumper than many other second-tier racing frames on the market. For example, the new Giant TCR Advanced frame offers a claimed weight of just 850 g, while Canyon’s comparable Ultimate CF SL frame has a figure of 980 g. And the Emonda SL’s higher frame weight is of course reflected in the complete bike weight, too, with our 54 cm SL 6 Pro tester tipping the scales at 8.01 kg (without pedals). 

Beyond the weight, the Emonda SL and SLR framesets are remarkably similar. They share the same moulds, and therefore the geometry and aero tube profiles are identical. Trek claims the stiffness profiles, and therefore ride quality is effectively equal. The way the cables are funnelled through the front of the head tube is the same, the new threaded T47 bottom bracket is mirrored, and likewise for the use of Trek’s reverser topper seatpost design. And heck, even the paint of our SL 6 Pro was an almost exact match to the SLR 9 that James tested.

Beyond the frame there are some more apparent differences. The SLR models feature a wonderfully light Bontrager one-piece carbon handlebar and stem, while the SL models use a more traditional bar and stem setup. And it’s a similar story for the other components which are lighter (and more expensive) on the SLR models. 

A race-ready geo and ride

The Emonda of old had two geometry options. There was the low and aggressive “H1” pro fit (offered in the SLR level only), and then the more mainstream “H2” with its more accessible and upright stack figure. For 2021 Trek combined those two fits into one with “H1.5” being used across all Emonda models. 

trek emonda sl6 disc 2020 review

That means the new Emonda SL is more aggressive than the last, and relatively speaking the reach figures are on the long side and the stack figures are fairly low. For example, our 54 cm tester offers reach and stack figures of 386 mm and 541 mm respectively, right in the realm of where many race-focused machines sit.

The handling is equally as sporty, with a traditional 73º head angle and 45 mm fork offset combining for a 58 mm trail figure with the control 28 mm Continental GP500 tyres fitted (25 mm Bontrager tyres are fitted as stock). And the wheelbase is kept fairly tight, too. 

Trek balances that longer reach by fitting a shorter-than-usual stem (90 mm on the 54 cm), and as a result the bike fits a little more upright than the figures may suggest. At the same time, that shorter stem produces a bike that handles even quicker and with less input than other race bikes with comparable trail figures. 

And it’s this quick-feeling attitude that will reward a rider with good handling skills. The Emonda can dive into turns and jump back out of them with little input. And it does that without an inkling of instability at speed. 

trek emonda sl6 disc 2020 review

Further rewarding a good handler is the stiff frame that pounces when called on and lets you feel what the tyres are doing through your hands and bum. No doubt, this was the firmest-riding bike we had at our small Field Test, and despite the wider 28 mm tyres, I could still feel the cracks and inconsistencies in the road surface. Thankfully that stiffness manages to find the right side of the line between a bike that speaks to you and one that skips about. 

Both Andy van Bergen and I agreed the Emonda was the most impressive under power when directly compared to the Giant TCR Advanced Pro and Canyon Ultimate CF SL , and similarly it beats the Specialized Tarmac SL6s that we both have sitting at our respective homes. I’d most liken the ride to BMC’s recently updated and stiffened Teammachine SLR01 . 

trek emonda sl6 disc 2020 review

That stiffness is great for riders who like out-of-the-saddle attacks and to feel their energy reach the rear wheel, but it’s less ideal for those seeking a smooth and compliant machine. And while many other brands utilise flexible seatposts to achieve more comfort through the saddle, Trek’s own reverse topper seatpost design just rides stiffer than the company claims and there are no options to change it for something more flexible – a somewhat surprising element given the company has gone to great lengths with its IsoSpeed technology to produce seated flex in its aero race and endurance platforms. 

Instead your best bet to add comfort to the Emonda is through the tyres. Trek officially states the Emonda can fit up to a 28 mm tyre, however that figure is extremely conservative. I trialled some 32 mm GP5000s (measured 32 mm width) in the frame without any sign of issue. 

trek emonda sl6 disc 2020 review

Compared to the previous version, living with the new Emonda frameset has some wins and losses. The new internal cable routing sees the brake hoses and shift cables enter through a funnel at the proprietary headset top cap, and then squeeze between the squared-off fork steerer and top headset bearing. It looks wonderfully clean, but as James previously covered, it does introduce some servicing difficulty, and that’s especially true for this model that uses mechanical shift cables.

Perhaps offsetting that servicing pain is the new T47 threaded bottom bracket , something that’s more universally compatible with oversized crankset spindles and surely simpler to service than Trek’s previous BB90 design that saw bearings pressed directly into the carbon frame. And while that new bottom bracket (made by Praxis) does require a unique tool, servicing it is vastly more accessible than with the former press-fit design.        

trek emonda sl6 disc 2020 review

I won’t get into the nitty-gritty of the aerodynamic design – we’ve done that – but I will say that the lines of this bike are quite stunning. The aero head tube is just so distinct, the wide and concave top tube offers a wonderfully interesting curvature, and similar can be said for where the long and flowing seat stays connect.  

The paint is also well done and makes this look far more expensive than it is. And as an added bonus there’s a second choice of colours, too (dark grey with chrome lettering). Although, perhaps Trek could have been a little more subtle with its logo, rather than turning the down tube into a rolling billboard. 

Carbon wheels aren’t always light

The tested Emonda SL 6 Pro sits smack bang in the middle of the Emonda’s range and features a full Shimano Ultegra R8020 mechanical groupset matched with a smorgasbord of Bontrager components (Trek’s own component and accessory brand).  

Below the SL 6 Pro (US$3,800 / AU$5,500 / £3,350) is the SL 6 (US$3,300 / AU$n/a / £2,900). The two bikes are effectively the same with the exception of the rolling stock. The cheaper SL 6 features Bontrager’s aluminium Paradigm Disc wheelset shod with the company’s R2 Hard-Case Lite tyres in a 28 mm size, whereas the tested Pro version moves to the carbon-rimmed Aeolus Elite 35 Disc wheels wrapped in a 25 mm version of the same tyre model. 

Adding US$500 to the bike’s price, those carbon rims offer a relatively shallow 35 mm aero-profiled rim that handles remarkably well without any sign of the flutter often present with deeper wheels in crosswinds. They offer a fairly modern profile, with an inner width of 19.2 mm and an outer width at 27.7 mm. However, the material is somewhat misleading and these wheels aren’t as light as you may expect. I weighed my sample set at 1,740 g for the pair (770 g front, 970 g rear).

trek emonda sl6 disc 2020 review

That weight doesn’t sound like much, but it impacted how the bike felt when attacking steep slopes, with Andy remarking that it made the bike feel sluggish to respond. Carbon isn’t always an upgrade. 

Another area that left Andy and I underwhelmed was the Bontrager Elite VR-C handlebar. We just didn’t get along with the ultra compact shape of the drops which left me complaining of wrist clearance issues, while Andy found that he was unable to make comfortable use of the drops due to his hand sitting proud within the tight radius. We both agreed that the handlebar would be the first thing we’d change.

Thankfully that’s the extent of our issues, and the rest of the build kit is hard to fault. Bontrager’s basic alloy stem works with its Blendr series of computer and light attachments (some of which are supplied), while the new Bontrager Aeolus Comp saddle features a modern short-nose design with a generous centre channel. And all the smaller details, including the proprietary headset top cap and seat post topper, add to a premium look and feel. 

trek emonda sl6 disc 2020 review

And finally there’s the Shimano Ultegra groupset. One thing James wasn’t able to test in his review of the SLR 9 was how the internal cable routing impacted mechanical shifting quality. I can confirm that it doesn’t. The shifts were just as snappy and consistent on this bike as they were on other bikes, and they should remain that way for a fair while with full-length housing used from shifter to derailleur. And that full-length housing should ease future repairs, although it does add to the bike’s total weight. 

Champagne tastes on a (craft) beer budget

Despite the lower price, Trek has done a solid job of bringing the Emonda SLR’s attributes to the SL. It offers the same handling, stiffness and aesthetic of its pro-level sibling, and that makes for an impressively enjoyable bike to ride.

However where the more expensive Emonda jumps with joy at every thought of an attack, the extra mass of the SL sees it hesistate somewhat. That difference may not be reflected on the clock, but it sure can be felt and it’s a constant reminder of the price tag attached to this ride. 

The new Emonda SL will be a good fit for the rider wanting a well-rounded race bike that handles and behaves like a WorldTour machine. However it’s best to avoid this one if you’re seeking an opulent ride quality or the lightest bike for the given sticker price.

Trek Émonda SL 6 road bike review

Giving the ride feel of a thoroughbred GC frame, Trek manages to deliver the perfect balance of stiffness and comfort in the elegant looking and reasonably priced Trek Émonda SL6.

  • Sign up to our newsletter Newsletter

trek emonda sl6

The Trek Émonda SL 6 exists a few places below Trek's signature SLR model but that doesn't stop it embodying the GC spirit and as a frame it certainly feels worthy of Alberto Contador.

It's made the coveted  Cycling Weekly's Editor's Choice list for its lightweight, fast and comfortable ride quality that'll have dancing up climbs like Contador himself. 

Think of top Tour de France bikes, and there are only a handful of names that pop into your head faster than the Trek Émonda.

While its old sibling, the Émonda SLR occupies the top echelons of WorldTour racing, we've got our hands on the more reasonably priced Trek Émonda Sl 6, coming in at £2,250.

Made famous in recent years beneath the likes of Alberto Contador and his Trek-Segafredo team mates, the Trek Émonda SL 6 feels like a thoroughbred GC frame regardless of its lower price point, and it's a frame that looks built to race yet still manages to maintain an air of elegance.

Trek Émonda SL 6 : c lassy looks

Sweeping lines blur one area of the frame into the other, and the slender seat stays make the bike look responsive and nimble. Pair the sweeping design with the matte silver paint job, and the bike has a seriously classy look.

But it isn't just surface, and the 500 series OCLV carbon makes the frame a skimpy 1091g. On our scales, the whole bike weighed in at 7.66kg, with any additional weight no doubt coming down to the components rather than the frame.

Down below, an overbuilt, beefy bottom bracket makes sure that every pedal stroke powers the bike forward – which is especially helpful when things start heading uphill.

Trek Émonda SL 6

Without a doubt, the most exciting equipment on the bike is the Shimano Ultegra R8000 groupset. Newly updated, it marks an enormous overhaul of Shimano's everyman groupset.

In terms of shifting feel and action, it's every bit as good as it's older, more expensive Dura-Ace sibling. The re-designed front mech and more ergonomic levers offer a light action to front shifts, and rear shifts are crisp, accurate and powerful.

Of the new Ultegra groupset itself, the most exciting feature are the excellent rim brakes – again, they're every bit the match to the Dura-Ace models.

With them being so good, it was a bit of a disappointment to find them missing on the Émonda. Instead, Trek has specced its Bontrager Speed Stop Pro brakes rather than Shimano's far superior rim brakes.

Bontrager's in house stoppers can't match Shimano's for neither feel nor power but it's an oversight we can forgive considering the Émonda's excellent frame and ride qualities. Besides, the Ultegra brakes are always going to be there for that next upgrade.

Trek Émonda SL6

Again, the Bontrager Paradigm aluminium wheelset could be lighter to match the svelte carbon frame but at this price point they're par for the course and they didn't feel like lead weights when heading uphill.

GC quality frameset

Out on the open road, the ride quality of the GC frame really shines through, and there's a sense of urgency laid up in the carbon that wants to let rip.

But there's a gentler side to it, too, and the high modulus frame gives comfort to the ride. Unlike so many stiff carbon frames, the Trek Émonda Sl 6 feels dampened and absorbent without that dreaded sluggishness that heavier bikes suffer from.

The skip in its step no doubt comes from its lack of weight, and even with the aluminium wheels and overbuilt brakes, the Émonda SL 6 weighs a tiny 7.66kg. Spoil yourself to some killer wheels and you'll bring that down even further.

Dancing out the saddle on the Émonda SL 6

On the hills it climbs like you'd expect from a frame built for Alberto Contador, encouraging you to imitate his signature out the saddle dance on the steepest inclines. But its a frame that really shines on the downs, too. The 992mm wheelbase is manoeuvrable but well balanced and the handling was sharp in the corners, everything you'd expect from a GC super bike.

The Émonda Sl 6's frame is faultless – lightweight, comfort and stiffness all in perfect equilibrium. Its more than a match for the aluminium wheels it comes with, but it has to meet a price point after all.

Émonda SL 6 Pro Ridden and Reviewed

Filter by category:, an early contender for "bike of the year".

Trek's launch of the new generation Émonda is a big deal. The previous generation was a very good bike but I felt it was out-classed by its arch rival the Tarmac SL6 (no harm there as the Tarmac was exceptional, but Trek and Specialized products are much closer in abilities in the aero road and endurance categories).

So a new Émonda is an exciting prospect; especially when the hype coming from the Pro teams has been so loud - this bike is aero enough that it will apparently replace the Madone as the main stage race weapon. That's some welcome extra versatility for a very light bike.

Being a bike tart I was initially focused on the top of the range Émonda SLR series (and I do have one on order).

But when we looked at the specs we realised the SL series (made with OCLV 500 carbon vs the 800 on the flagship range) looked a cracking bike for the money, and the pick of the bunch was the SL 6 Pro at £3350. A lightweight climbing bike with aero advantages, Ultegra disc groupset and carbon wheels. That's a heck of a bike for the money.

And it comes in a super smart Lithium Grey / Brushed Chrome finish (well, these things matter too!) that belies the price point.

In the first week it was launched we sold 10 of the SL 6 Pros; everyone loved it and I said to Dan that based on spec and first impressions this was a (very) early contender for 2020 Bike of the Year. And so, in the interests of editorial thoroughness, I decided to buy one myself and see how it performed.

I have wheelsets that cost more than this entire bike; so I was really keen to see how it performed vs the £9000 super bikes I kid myself I 'need'.

trek emonda sl6 disc 2020 review

Initial impressions

On unboxing my first impressions were immediately very positive; it looks very smart indeed. I have always loved dark grey (slightly darker than Nardo grey if you are a car geek) and the chrome decals really set it off. Its a really good looking bike, with a sleek look from the aero tubes that still manages to be quite 'classic' in profile.

The SL range don't have the trick one piece bar/stem that features on the SLR models. Instead it comes with a separate alloy stem and an alu bar with Bontrager's VR-C shape. This is the first time I have ridden them and they are long - 100mm reach when most bars are 75-80mm; so my maths shows that all things being equal you need to lose some stem length. My bike comes with a 110mm stem in 58cm, and truth be told I might go down to 100mm (which hurts the ego... but fit matters!). But the bar shape overall is great, and the drops are super useful.

The saddle is the new Aeolus shape; with a massive pressure-relieving cut out in the middle, running almost the full length of the saddle. It comes in a posh one at £150 (with carbon rails and shell), a middle range one at £90, and this 'budget one', the Comp, which retails on its own at £49. The Comp is relatively heavy at 280g, thanks to steel rails, but that's my only issue with it; the shape is great and £49 for a saddle this good is outrageous value for money.

trek emonda sl6 disc 2020 review

I like mechanical Shimano; I have Dura Ace 9000 and 9100 on other bikes; but this was the first time I have ever owned a bike with a mechanical disc groupset. As ever with Shimano shifting is flawless, and I really like the shape of the hoods (whisper it, but more than the Di2 version) as there is a lot to grab hold of; its closer in size to AXS than Di2 (and to me, thats a good thing).

My only change from the stock bike is to put my SRM power meter crankset on the bike, replacing the stock Ultegra crank. Everything else is 'as is'.

Those carbon Aeolus 35 wheels look the part, the only thing I would recommend changing from stock immediately is the Bontrager R2 tyres which are decidedly 'budget' in feel and don't roll that well. You can feel the stiffness in the casing, and a more supple tyre would improve the ride and handling at little cost.

I popped on a set of my favourite Specialized Turbo Cotton 320TPI in 28mm and it really made the ride come alive. Sacrilege, I know, but they're what I had to hand. Something like the Vittoria Corsa would also be a superb option when you're looking to upgrade from the stock tyres, that supple casing makes all the difference.

Ride impressions after 4 rides

It's still early days; but I have tested enough bikes to know that good bikes rarely become bad, but sometimes bikes you don't immediately gel with can come good with some small positional or component tweaks.

I am pleased to say the Emonda SL 6 Pro is simply a very good bike from the off. I had to keep reminding myself it was 'only' £3350; apart from some small weight gain and cheaper tyres it rides like a bike that costs double this. Swap the tyres out and it's even better.

Trek have mirrored the Madone geometry. There's no longer the choice of H2 (moderately relaxed) or H1 (Pro aggressive), but instead they've gone to H1.5 across the range. This to me is a welcome development - it's a Goldilocks geometry; aggressive enough to be racey but not so low or long as to need lots of spacers.

It's hard to 'feel' the aero gains of the new Émonda; I am coming off a Venge with 65mm wheels so that's setting a pretty high benchmark. But it doesn't feel slow on the flat by any means; it's certainly competitive (especially vs the old Émonda which was a bit of a brick wall aerodynamically). Where it does shine is uphill; the thing just flies.

I have read some people think the SL 6 rides 'harsh'; I certainly don't agree. Direct and responsive yes, but definitely not harsh, and swapping out to 28mm tyres (vs the stock 25mm) has improved things further, without any downsides.

trek emonda sl6 disc 2020 review

Upgrade pOTENTIAL

Trek offer the Émonda SL 6 as standard in two variants; the SL 6, at £2900 with Bontrager Paradigm alloy rims and the SL 6 Pro at £3350, which is the same bike but equipped with Bontrager's Aeolus Elite 35 carbon wheels.

Both wheelsets are tubeless ready, but the Paradigm are a fairly "entry level" wheelset, tough and durable but not especially matching the light weight of the frame (at approx 1750g per pair). So for the relatively small uplift in price it's no surprise that the SL 6 Pro is proving to be vastly more popular, it's a really cost effective way to get some decent carbon wheels from the offset.

I was really impressed with the 35mm deep Aeolus Elite carbon wheelset in my testing, it packs a lot of punch for the money, part of the new generation of superb value wheels that have reduced the cost of entry to carbon.

The Émonda SL though is a bike that makes a perfect platform for upgrading over time, it's such a strong base to build on. I couldn't resist trying it with some of my other wheelsets (some of which are £2000+ and thus 2/3rds of the bike's price!). You can tell a good bike when good wheels "lift" it further.

That's certainly the case here, and as seen in my photos I've been putting in some miles on the ENVE SES 5.6 and my Rovals, both of which take things up a notch further still. With a high-end wheelset the SL 6 really flies, it can hold its own with bikes costing much more.

trek emonda sl6 disc 2020 review

As you can tell, overall I really liked the bike. It's an outstanding privateer's race bike; for £3350 it offers everything you need; an aero climbing bike, with disc brakes and carbon wheels. The pace of technology is such that this is better than a £10,000 bike was a generation ago...

Of course me being me, I can't help but wonder when I get the SLR frame (rumoured to be 400gm lighter than the SL one) just how good it will be! But that'll get its own review, I'll just have to wait...

In the meantime the SL 6 is already proving to be a justified sales success for Trek, and has got the revamped Émonda line off to a superb start. If you're looking for an exceptionally capable race day bike and this fits your budget, it's got to be on your (very) shortlist. Its the most impressive new bike I have ridden in 2020.

The New Trek Émonda Is Faster Than Ever

Already one of the fiercest climbing bikes available, the new Émonda is even faster thanks to a dose of aero.

The Takeaway: The Émonda SLR is a benchmark pro race bike—and it’s surprisingly rider friendly.

  • It has 183 grams less drag than the previous generation, but the frame is only 33 grams heavier
  • There are 10 models starting at $2,699
  • SL models ($2,699 to $5,999) have the aerodynamic shaping and features but in a frame that’s about 400 grams heavier than the SLR
  • SLR models ($6,699 and up) use a new carbon fiber composite that’s 30 percent stronger than Trek’s previous top-of-the-line carbon.

For Émonda SLR bicycles, Trek will provide an individual handlebar and stem until an updated handlebar/stem combo is available.

Additionally, all customers who bring in their handlebars for replacement will also receive a $100 in-store credit that can be used toward any Trek or Bontrager merchandise through December 31, 2022.

Remember professional road racing ? It’s that thing where super skinny people go unbelievably fast up and down hills and fly over flat roads for hours at a time. It’s been a while since the pros have beat up on each other for our entertainment, but there might, hopefully, be some races on the horizon. When the races do resume, Trek’s pro riders will be aboard its new third-generation Émonda climbing bike. The new Émonda isn’t lighter, but it is faster thanks to a dose of aerodynamic tuning.

A built-in chain watcher prevents unwanted derailments.

Making the new Émonda frame more aerodynamic wasn’t exactly a tough hurdle as the previous Émonda had virtually zero aerodynamic optimization. But adding meaningful aerodynamic benefit while achieving the frame stiffness expected of a pro-caliber race bike, maintaining the well-regarded handling properties of the previous Émonda, and adding rider-friendly features like a threaded bottom bracket—all with adding only 33 grams (SLR frame, claimed)—is quite a feat.

Below you’ll find my review of the Émonda SLR—I’ve been on it since early March—followed by a dive into the technology and features of the new bike, and a brief model breakdown.

Ride Impressions: Émonda SLR 9 eTap

trek emonda slr 9 etap

The Émonda SLR is a tool made to fulfill the needs of some of the world’s best road racers. This bike will never be as comfortable or versatile as a gravel bike. Going fast on pavement and climbing performance are its only goals. These are obvious facts, but that’s the lens through which it must be viewed. And through this lens, it is one of the very best.

The new Émonda was born out of a request from Trek’s pro racers and pitched as the company’s “fastest climbing bike ever.” So little surprise they set me up with the lightest model (the SLR 9 with SRAM Red eTap ), which also has a build kit almost identical to the team’s bikes. It’s also, excepting customized Project One builds, the most expensive model at a buck under 12 grand.

That massive pile of clams gets you an aerodynamic frame with disc brakes, power meter, and wireless electronic shifting that weighs less than 15 pounds (54cm). And that’s with a hefty T47 threaded bottom bracket unit, lustrous paint , clincher wheelset, a chain-watcher, standard butyl tubes, 37mm deep rims, 160mm disc rotors front and rear, and SRAM’s largest Red cassette (10-33). That’s “Holy shit!” impressive.

By cutting drag a ton without adding much weight, it’s hard to argue with Trek’s claim that the new Émonda is faster than the outgoing generation. But if you have any doubts, they’ll be erased when you ride it. This is an explosive bike: it feels as light as a feather and as solid as a steel girder at the same time.

trek emonda slr 9 etap

Trek’s Émonda has always been a raw and rowdy bike that feels a little wild and a bit dangerous in precisely the ways you want a race bike to feel: That’s not lost with the added aerodynamics. If anything, the new Émonda is even crisper and punchier than before, which is saying something.

preview for Tested

A small downside to all this fury is the Émonda’s smoothness. Light and stiff race bikes aren’t a smooth-riding lot to begin with, but even measured against a stiffer riding genre, the new Émonda is on the firmer end of the scale. Still, it escapes harsh or punishing labels—I did a six-hour ride on the Émonda on the stock 25 tires and didn’t feel worn down by its ride. Swapping to 28s helped a lot (no surprise) and were on the Émonda for the bulk of my testing. I’d suggest reserving the lighter and more aerodynamic stock 25s for racing or PR attempts—assuming good roads—and use 28s as daily drivers.

The Émonda’s handling is excellent. Well, let me caveat that: Road racing geometry is pretty uniform, so whether I’m on a current race bike from Trek, Specialized, Cannondale, Cervélo, Canyon, Colnago, Wilier, Pinarello, BMC, Giant (etc., etc.), I find the broad strokes of their handling feel and performance quite similar. There wasn’t anything about the Émonda’s handling or cornering performance that set any new benchmarks for me, but there wasn’t anything to dislike either.

It was quick and accurate, diving into corners with a light touch. It offered great feedback, so I always knew where I was relative to its and my limits, and I could count on it to be consistent and predictable. It was maybe a touch less settled in bumpy corners than the Specialized Tarmac, but the Émonda never broke traction or skipped. Overall, for such a light bike, the Émonda is remarkably solid and drama free. I’d have no qualms barreling down a technical alpine descent on the Émonda.

I received this test bike in early March, giving me plenty of time to ride it back to back with its primary competition—a Specialized S-Works Tarmac , what I consider the benchmark for aero-ized lightweight bikes. The Tarmac is smoother over the bumps and has a silkier feel overall, but the new Émonda feels more efficient, like it can go faster more easily.

I’ve also ridden a good slice of the Émonda’s competition, including the Canyon Ultimate CF SLX , Colnago V3Rs, Cannondale SuperSix Evo , Cervélo R5, Wilier Zero SLR , Pinarello Dogma F12 . These are all superb bikes, but I feel the Émonda is the class leader. It feels sharper and more explosive than all of them. It feels faster, and that’s what matters most in a race bike. But I also like that the Émonda is pretty straightforward and rider-friendly.

trek emonda slr 9 etap

For example, I swapped the stock one-piece bar/stem for a standard stem and round bar. One, I could run a standard bar and stem on this bike, which you can’t say about every modern race bike. And two, I didn’t have to pull any cables, wires, or hoses to make the swap: Again, something you can’t say about all race bikes. For the record, the shape of the one-piece Aeolus bar/stem is great, and the tops are the most comfortable to grab of all the aero-topped bars I've used. The only reason I swapped is my preferred length and width combination (110x40) wasn't available yet.

The BB is threaded, which makes it easier to service and replace than a press-fit (however, I was getting some noise out of the BB area, which I never resolved). The wheels employ standard offset, and it uses regular thru-axles. It’s compatible with pod-style power meters and mechanical shifting. Its signature seat mast is pretty much the only non-standard thing about this frame, and even then, it’s pretty user-friendly. There’s no cutting necessary, height adjustment is ample, the saddle clamp is easy to use, and it’s travel-case friendly.

trek emonda slr 9 etap

I expect so much from a modern high-end pro-level road racing bike that it’s hard to exceed those expectations. It’s rare when a bike does: The Émonda SLR is one of those rare bikes.

Team Request

The new Émonda is partially a result of a request from the Trek-Segafredo race team. “They are one of our primary customers,” said Jordan Roessingh, Trek’s director of road product. “And they started to realize that it’s not just weight, it’s not just stiffness and responsiveness, there’s this other thing—aerodynamics and speed—that’s also really important to be competitive and be faster on the bike. They had been one of the loudest voices saying, ‘We need the lightest-weight, stiffest bike possible.’ And now they started coming back saying ‘We need those things, but we also need the bike to be faster in order for us to be really competitive.’ ”

It is (comparatively) easy to make a light frame, it is easy to make a stiff frame, it is easy to make an aerodynamic frame. Making a frame that’s two of those three things is more challenging: Making a bike more aerodynamic usually makes it heavier, making a bike lighter typically makes it less stiff, etc. Making a frame that is light AND stiff AND aerodynamic enough to satisfy the demands of a top-level professional race team is extremely difficult.

trek emonda slr 9 etap

But not impossible. Many brands already make a light, stiff, and aero bike. The Specialized Tarmac is one, as are the Canyon Ultimate, the Cannondale SuperSix Evo, the Cervélo R5, the Wilier Zero SLR, the Pinarello F12, the Scott Addict, and the new Giant TCR . All of them seek to balance the three qualities—light, stiff, and aero—in the pursuit of the ideal race bike, and they all manage the balance differently. The common thread between these bikes: They’re all used by teams that compete against Trek-Segafredo.

Still Light, Now With Aero

The previous generation Émonda SLR Disc , launched in 2017, was an extremely light frame at 665 grams (claimed). But when a frame is already that light, it is much harder to make it even lighter. At least lighter enough to make a meaningful difference.

emonda drag chart

So, Trek took a different approach to making its climbing bike faster—instead of lighter, it made it more aerodynamic. The new Émonda frame is a touch heavier—yet still extremely light at 698 grams—but the bike has 183 grams less drag than the previous generation.

The important thing to note here is that, though the frame is more aerodynamic, the 183 gram drag reduction is not from the frame only. New wheels and a new aero bar (more info on both below) play a role. The specific setups Trek used to get that 183 gram number are: 2018 Émonda with 28mm-deep Bontrager XXX 2 wheels, and Bontrager XXX Bar/Stem Combo compared to the 2021 Émonda with 37mm deep Bontrager Aeolus RSL 37 Wheels and Bontrager Aeolus RSL Bar/Stem Combo.

trek emonda slr 9 etap

Another drag saving upgrade: the housing, hoses and wires for the controls are almost fully inside the frame. They dive into the frame at the head tube passing through the upper headset bearing. The front brake hose runs into the fork steerer and down the left leg before popping out just above the brake caliper. The fork steerer’s flattened sides provide room for the rear brake hose and derailleur control lines to travel down and into the frame. Though it has flattened sides, the fork steerer is still compatible with standard 1 1/8” stems.

The overall drag reduction results in a bike that is 18 seconds per hour faster when climbing an 8.1 percent grade (the average grade of Alpe d’Huez ), and 60 seconds per hour faster on flat roads than the previous Émonda. Trek also claims the new Émonda is 13 seconds per hour faster than a Specialized Tarmac when climbing an 8.1 percent grade (all assuming the rider maintains a constant 350 watts).

Eight Point One Percent

With three qualities—aero, stiffness, weight—that work in opposition to each other, how do you decide how much to optimize one quality when you know it will negatively affect the other two? How aero is aero enough? At what point is improved aerodynamics offset by the weight added to get there?

The team behind the Émonda used a legendary climb to help them decide: Alpe d’Huez. “It represents an extreme example of what most people see on a regular basis when they’re doing a big climbing ride,” said Roessingh, “It’s around an 8 percent grade, and it’s about an hour-long climb for the pros—amateurs might go a little slower. It gives us a good understanding of what the benefit of a drag savings is relative to a weight savings.”

trek emonda slr 9 etap

By optimizing the weight and aerodynamic balance around this climb, Roessingh claims the Émonda is faster on Alpe d’Huez and also faster on everything shallower than the famous climb, “which is the vast majority of the environments that most riders are going to ride in, including the team,” said Roessingh. “So if we can say it’s faster up Alpe d’Huez, it’s going to be significantly faster everywhere because the flatter it is, the more aerodynamics benefit you.”

Computer-Aided Optimization

Achieving the weight to the aerodynamic balance of the new Émonda required careful design of each tube shape. Aiding the Émonda’s team was supercomputing horsepower. The abridged and simplified version of the process goes like this: into the computer was fed a rough draft of the shape based on Trek’s aerodynamic experience and other information like UCI regulations. The program then varies the tube’s parameters within a predefined range and spit back several iterations of the shape, each with a different weight to aerodynamic balance. The Émonda’s team evaluated the alternatives and picked the one most suited to its location in the frame and best able to help the frame achieve its overarching goal.

Roessingh says that Trek cannot afford to buy the computing hardware necessary to run the CFD and FEA optimizations (in a timely manner) that helped shape the new Émonda’s tubes. The processing happens in the cloud where Trek rents time on Google, Microsoft, or Amazon’s supercomputers. It’s more affordable than buying a supercomputer. Even so, it is not cheap, “Cloud computing is becoming a relatively significant budget line item for us because we’re doing so many of these optimizations in CFD and FEA and all that processing happens in the cloud.”

tube shape comparison of the generation two and three emonda

The new Émonda’s fork legs, head tube, down tube, seat tube, and seat stays all use a variation of a truncated airfoil. The top tube and chainstays, which have virtually no effect on drag, are optimized almost entirely for stiffness to weight.

In Trek’s line, the new Émonda’s aerodynamic performance is equal to the third generation Domane ; the Madone is still significantly more aero. But while the more aerodynamic Madone is faster in flatter terrain, once the climb hits about 5.5 percent, the lighter Émonda becomes the faster bike. And for many of the Trek-Segafredo team riders—and many amateurs—that means the Émonda is fastest when it matters most: the hardest part of a race or ride, which is almost always on a steep climb.

trek emonda slr 9 etap

OCLV 800 Carbon

Getting the new Émonda SLR to be as light as it is while adding aerodynamic shaping would not be possible without employing a new carbon-fiber composite, said Roessingh. The new OCLV 800 composite is 30 percent stronger than Trek’s previous top-of-the-line composite (OCLV 700). Because it is stronger, they can use less: By using OCLV 800, Trek’s team was able to make the Émonda SLR frame 60 grams lighter than if they used OCLV 700.

trek emonda sl 5

The Émonda SLR is very cool, but it’s also very expensive (bike prices start at $6,699). For the 99 percenters, there’s the Émonda SL (models start at $2,699).

The SL uses OCLV 500 composite, and the frame is quite a bit heavier than the SLR’s. The SL’s frame comes in at 1,142 grams, with a 380-gram fork (SLR fork weight: 365 grams).

But material (and weight) are the only difference between the SL and SLR.

Aeolus Bar Stem

While a ton of work made the Émonda’s frame tubes faster, a big chunk of the new bike’s drag savings comes from the one-piece Aeolus bar stem. It alone is responsible for 70 grams of the Émonda’s 183-gram drag reduction. This means that if a traditional stem and round bar are installed on the new Émonda, its drag advantage over the previous-generation bike drops to 113 grams. And it means that you can make any bike with a round bar and traditional stem significantly more aerodynamic by merely installing the Aeolus. Retail price is $650.

trek emonda slr 9 etap

The integrated Aeolus is made of carbon-fiber composite, of course, with a claimed weight of 297 grams (42x120). It’s offered in 14 length and width combinations, from 44x120 to 38x80. Hoses, housing, and wires run externally for easier service and repairs, but in a groove that keeps them out of the wind. A bolt-on plate keeps the control lines tucked and organized where they turn off the bar tops to run in line with the stem.

The Aeolus employs a mount that works with Bontrager’s line of Blendr accessories for mounting computers and lights.

Aeolus 37 Wheels

Another new Bontrager product rolling out with the Émonda is the Aeolus 37 wheelset. It comes in two models: the Aeolus RSL 37 (1,325 grams/pair, $2,400) and the Aeolus Pro 37 (1,505 grams/pair, $1,300).

trek emonda slr 9 etap

The RSL 37 is claimed to be lighter than Zipp’s 32mm-deep 202, yet more aerodynamic and more stable than Zipp’s 45mm-deep 303. Both wheels are disc brake only (only Center Lock interface), tubeless compatible, use DT-Swiss internals, have no rider weight limit, and come with a lifetime warranty.

Surprisingly Rider Friendly

Though the new Émonda is clean and integrated looking and uses high-performance standards, it is also remarkably rider-friendly. Cables, hoses, and housing run externally on the one-piece Aeolus bar/stem for easier repair and service (with one exception: wiring for a Shimano Di2 or Campagnolo EPS bar-end junction box runs partially inside the bar). If you prefer a more traditional cockpit, it can be run with a standard bar and stem with 1⅛-inch steerer clamp.

The bottom bracket uses the threaded T47 standard , which is compatible with almost all common crank-axle standards.

trek emonda slr 9 etap

Front and rear thru-axles are standard 12x100 and 12x142mm, and the wheels employ a standard dish. The standard flat mounts for the brake calipers are compatible with 140, 160, or 180mm rotors.

Tire clearance is officially 28mm, but that’s with a ton of extra space. I fit 32mm tires in the Émonda with ease.

And though all models do use a seat mast, it’s a no-cut variety with lots of adjustment range.

H1.5 Geometry

Trek did offer its top-of-the-line race bikes in the aggressive H1 geometry for riders seeking an ultra-long and low geometry, or H2 which was an endurance fit. The new Émonda is offered only in H1.5, which splits the difference between H1 and H2. The result is pretty typical dimensions for a modern race bike—a 54cm Émonda H1’s geometry is remarkably similar to a 54cm Specialized Tarmac.

There are eight sizes starting at 47cm and topping out at 62cm.

emonda sl 7 etap

There are 10 models of the new Émonda. SL models start at $2,699 and are priced up to $5,999. SLR models start at $6,699 and go up to $11,999.

Only SLR models come with the Aeolus integrated bar/stem stock; and only the Émonda SL 7 ($5,499) and up come with the Aeolus 37 wheelset.

The new Émonda is a disc brake-only platform.

Project One

The new Émonda is in Trek’s Project One paint and parts personalization program. If that’s not luxe enough for you, Trek’s Project One Ultimate program allows you to work with a designer to come up with a one-of-a-kind finish, and Trek will source any parts you want for your new bike.

Trek Emonda SL6 Pro – Review 2023  

  April 7, 2022

By   m bhatia

Trek Emonda SL6 Pro

Trek just introduced a totally new re-imagining of the Emonda , the brand's lightweight climbing/GC model platform, with a substantially aero-ised chassis. The model family is divided between a higher-tier SLR range and a lower-tier SL range, which this SL6 Pro falls under; the key distinction is in the carbon layup and the increased integration of the SLR range.

Emonda SL6 Pro frame design and size:

The Émonda has always been Trek's lightweight road bike , leaving outright speed to the Madone, but with this current edition, Trek has incorporated more aerodynamic profiles into the Émonda's design.

Unlike other aero bikes, the Émonda's frame isn't designed to be fast in a straight line or at high speed; after all, it's a climbing bike. Instead, the engineers have concentrated on 'unsteady aerodynamics,' which correspond to the significantly lower speeds encountered when ascending. 

The front end, including the head tube and down tube, has received the most attention. The top-tier SLR models employ the Bontrager XXX aero handlebar /stem combo, which boosts the benefits even more, but it isn't available on the SL variants.

The SLR versions also utilize a new OCLV 800 grade carbon fiber, whereas the SLs use the 500 series, which adds some weight, but a reported frame weight of 1,142g and 380g for the fork is far from shabby.

What are the different parts included in Trek Emonda SL6 Pro?

According to Trek, the SL 6 Pro comes equipped with all of the lightweight components needed, thus there is no need to upgrade. You could save a few grams here and there, but it's a full package.

This is the first carbon bike in the lineup to include carbon fiber wheels. The Bontrager Aeolus Pro 3 wheels are deep and tubeless-ready.

Trek included a full Shimano Ultegra hydraulic/mechanical groupset on the SL 6 Pro, which fits the bike perfectly. You get close to Dura-Ace performance at a far lower cost.

Trek has specified a 50/34-tooth semi-compact chainset and an 11-28 cassette, which is an excellent gear ratio selection for a bike of this design. There are plenty of top-end gears for speed work, and the 30-tooth sprocket provides an extra bailout gear above the more common 28T seen on most race bikes.  

Ultegra's gear changes are excellent. The levers have a light feel to them, but they also provide a very well-defined click, letting you know that the shift has occurred.

Trek has chosen to put 160mm rotors front and back, which provide more than adequate power for a bike of this size.

Shimano's hydraulic systems are incredibly powerful, but they're also very easy to adjust, thanks to a lot of sense through the levers, which allows you to stop quickly without concern of locking up the front tire, even in wet conditions.

How does it feel to ride an Emonda SL6 Pro?

The first thing to note in this new incarnation is that the lower SL version feels a little thick at over 8 kilograms - not what you'd expect from a bike whose primary purpose is all about lightweight and climbing. However, total mass does not necessarily correlate to an anchor of a ride experience, and the Émonda is no exception. 

Trek has managed to offer a level of stiffness around the bottom bracket that allows the Émonda to deliver on its promise of rewarding effort. Granted, it requires less work to sustain speeds on flat and undulating terrain, similar to the Madone aero bike , it's a 'faster' bike than the previous version.

But this new design has repressed part of the prior model's lively and exhilarating ride style - it feels like using terms such as solid and trustworthy is more suitable, nearly like the Domane endurance bike .

What We Like

  • A race bike with suitable geometry.
  • High-end appearances.
  • Greater tire clearance than claimed.
  • Bottom bracket with threads.
  • Shimano Ultegra is difficult to fault.
  • Excellent saddle.

What We Don't Like

  • Ride quality is stiff.
  • Heavyweight carbon wheels.
  • Handlebar bend is very tight.  

Is the Emonda SL6 Pro Trek bike value for money? 

The bike is based on a complete Shimano Ultegra R8020 groupset. It's nearly tough to criticize R8000, which provides nearly all of the performance of Dura-Ace at a far lower price.

The crankset is 50/34, and the cassette is 11-28. This is an excellent choice for a go-fast, climb-friendly all-around bike.

It's worth mentioning that the bike has a short cage mech, which legally limits the drivetrain to a 30t cassette. If you need lighter gearing, you'll have to go with a smaller set of chainrings.

Nonetheless, the gearing provides more than enough range to climb comfortably in the saddle on the majority of climbs. 

The SL6 Pro is the 'lowest priced' bike in the new Emonda lineup with carbon wheels.

Is Trek Emonda good for climbing?

The new Trek Emonda isn't much lighter or stiffer than the previous model, but it is purportedly more aerodynamic - a clever trick since it still looks like a regular bike. The bike is an excellent climbing partner, as you might expect. The reduced weight, as well as the remarkable chassis rigidity, are immediately noticeable. 

What's the difference between Emonda SL6 and SL6 pro?

The SL6 Pro is part of a model family that includes a higher-tier SLR and a lower-tier SL range, with the key differences being the carbon layup and greater integration found in the SLR series. Trek's 500 Series OCLV carbon fiber is used to build the Emonda SL6 Pro's frame.

What is Trek Emonda SLR?

The Émonda SLR  is an ultralight, aerodynamic carbon road bike designed to be the fastest climbing bike we've ever built. Thanks to aero tubes crafted from our lightest OCLV layup ever, you get the legendary riding quality of our lightest platform, plus greater speed. 

What is the difference between Trek Domane and Emonda?

Trek Emonda is a race road bike with a light frame and aggressive geometry, while Trek Domane is an endurance road bike with a slightly heavier frame and more relaxed shape.

Can you use a gravel bike for touring?

Yes, if you ride an adventure-ready gravel bike, it could be the ideal bike for your next trip. These bikes often feature a stack/reach ratio of over 1.5, with chainstays ranging from 430 to 445 mm, which are suitable for a well-balanced gravel bike for touring.

The Endnote:

Overall, the Émonda is a fantastic bike. The aero changes have transformed it into a really fast and efficient bike that still manages to deliver on the weight front, and this SL 6 Pro model is so perfectly specced that there's no need to update anything in terms of components except the tires when they wear out. It boasts a high-quality frameset that performs well both on the flat and on the climbs, and it is well-specced for the price.

Trek Émonda SL 5 Disc

Trek Émonda SL 5 Disc

At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Good scores are more common than bad, because fortunately good products are more common than bad.

  • Exceptional
  • Not so good

Trek's Émonda SL 5 Disc is a solid all-round race bike offering great handling, a stiff platform for performance and a comfortable riding position, plus it's all wrapped up in a minimalistic, clean-looking package. This build isn't exactly lightweight though.

Trek launched this latest Émonda design last year, giving what has always been considered its lightweight climbing machine an aerodynamic makeover that takes it into what I consider quality all-rounder territory.

From a ride point of view, I can't fault it. It's firmer than a lot of carbon bikes on the market, and I kind of like that. Getting smashed about isn't fun, but neither is a bike that mutes all the signals from the road below. The Émonda balances this well.

trek emonda sl6 disc 2020 review

Stand hard on the pedals for a climb or sprint and the bike feels tight everywhere, although most notably around the bottom bracket area. There is no flex anywhere, and it just eggs you on to keep hammering away when your legs are screaming to ease up.

Chubby chaser

The only downside is that this SL 5 build's weight can just take the shine off. This 56cm model weighs in at 9.16kg, which is on the beefy side for a near three-grand bike.

The SL 6 Pro I rode last year came with an Ultegra mechanical groupset and 35mm deep Bontrager Aeolus Elite carbon wheels, and weighed 8.23kg. It felt much nippier than the SL 5 when it matters.

As an experiment I switched the SL 5's wheels for a pair of 1,400g Scribe Élan Wide+ 42-D wheels I had on test, and that unlocked the Émonda's potential. I'm not saying you should go out and blow £1,190 on newwheels, just that you shouldn't be put off by the standard weight of the SL 5. It can be tweaked without spending a fortune in the future.

On all but the steepest of climbs though, the Émonda doesn't feel as heavy as the road.cc scales would suggest. It still feels nippy as you accelerate out of corners or crest those short power climbs, and it always seems to have an eagerness to keep rolling.

Right angles

The geometry helps too. This is a proper race bike with a steepish 73.5° head angle for quick steering, plus a short 151mm head tube to allow a low front end and a short wheelbase. At just 983mm, this certainly gives it a nimble and flickable feeling in the bends.

2022 Trek Emonda SL 5 Disc - fork.jpg

On the downhills I found I could let the Émonda go even when the road surface was less than perfect. It just feels really planted, and coupled with that firm frame passing through loads of feedback from the tyres, I left me feeling perfectly in tune with it.

The steering is on the fun side of neutral, and allows you to just point the handlebar and aim for the apex. The Émonda is also very responsive to slight changes in body position if you need to tweak your line or get yourself out of trouble. I found this out when riding somewhere I had never ridden before – a descent which was easily 40mph+ in sections.

The Trek just nailed it, even though I didn't know what was around the next corner. With less caution than I probably should use, I could throw the Émonda through the bends while constantly making little tweaks to my position to line it up for the next one.

The SL 5 is also a quality mile muncher. The firm ride didn't seem to fatigue my joints any sooner than normal, and although the position is racy, it isn't extreme either. I could ride on the hoods for hours without discomfort and made good use of the shallow drops too.

Frame and fork

As I mentioned earlier, the Émonda focuses more on aerodynamics now than ever before, but that doesn't mean it has become a rocket ship on the road. The Émonda is a climbing bike after all, so Trek's engineers have honed in on 'unsteady aerodynamics,' which they say give larger effects at lower speeds when ascending, rather than on curves for cutting through at high speeds in straight lines.

For starters the front end has been made as smooth as possible, with all cables and hoses directed through the head tube into the frame and fork, giving a very clean look. The head, down and top tube junction is large and beautifully sculpted for airflow too. As a whole the Trek has been optimised for 25mm tyres, although it will swallow 28mm with 6mm of space around the tyre.

2022 Trek Emonda SL 5 Disc - fork clearance.jpg

The integrated spacer is designed to line up perfectly with the frame when the handlebar is pointed straight ahead, although it does limit how far the bar will turn in each direction. It can feel a bit daunting at first – I kept worrying I might not have enough lock to negotiate a tight turn at low speed.

It proved an unfounded worry though, and the only time I reached the turning limit was when trackstanding at the lights.

Trek Emonda SL5 Disc

The top-end Émonda SLRs use a carbon fibre all-in-one handlebar and stem to take things even further, but there isn't the budget for that here.

As for the seatpost, Trek has decided to do things a little differently. The seat tube extends high, up past the top tube by some way. An external seat mast slides over the top and clamps into position, and the seat tube inside the mast allows a bit of flex, which aids comfort.

2022 Trek Emonda SL 5 Disc - seat tube junction.jpg

The top tube flares out at the seat tube junction, which I find I often rub my thighs against. I got around it by running the saddle 5mm further forward, but it's worth bearing in mind if you have large legs.

2022 Trek Emonda SL 5 Disc - seat stays.jpg

The frame and fork are created using Trek's 500 Series OCLV carbon fibre. It's a bit heavier than the new 800 Series found on the more expensive SLR range, but still gives a reasonable claimed weight of 1,142g for the frame and 380g for the fork. There are a massive eight sizes available, too, ranging from 47cm up to 62cm.

The Émonda range is now disc brake only, which means you're getting 12mm thru-axles and flat mounts for the disc calipers.

Trek has gone down the T47 bottom bracket route. Standard threaded bottom brackets have the bearing cups sitting outside the frame, which limits the width the bottom bracket shell can be without pushing the Q-factor (the distance between the pedals) too wide.

2022 Trek Emonda SL 5 Disc - bottom bracket.jpg

To allow a wider shell, which in turn lets the down tube, seat tube and chainstays all have larger joins for increased stiffness at this crucial point, many brands use press-fit cups. These sit inside the frame, allowing a wider shell while keeping the Q-factor the same. In the past there have been creaking and wear issues due to slack tolerances between the cups and the frame, though, so some people have fallen out of love with them.

The T47 is kind of the best of both worlds, as the bearings sit inside the frame but they are threaded into place rather than pressed. That gives a better (and easier) fit, but still allows for that wide bottom bracket shell.

To finish everything off, the SL 5 is available in two colours: this Quicksilver/Brushed Chrome, or Carbon Blue Smoke/Metallic Blue, which I reckon looks even better.

Finishing kit

The SL 5 is adorned with a Shimano 105 R7000 11 speed groupset, which cannot really be faulted, either from my own experience of riding it for thousands of miles on test bikes, or from Dave's in-depth review from a couple of years ago.

2022 Trek Emonda SL 5 Disc - crank.jpg

The gear shifting is precise and works well even under load – especially at the chainset – and the feel at the lever is practically the same as Ultegra R8000.

2022 Trek Emonda SL 5 Disc - UCI sticker.jpg

Trek has paired a 50/34t chainset with an 11-30t cassette, which gives a decent spread of gears for a bike with racing intentions. Crank length is determined by frame size, ranging from 165mm to 175mm.

2022 Trek Emonda SL 5 Disc - cassette.jpg

Alongside the flat mount 105 calipers the SL 5 uses 160mm SM-RT70 rotors front and rear.

2022 Trek Emonda SL 5 Disc - front disc brake.jpg

Stopping power is great, as is the modulation and control.

If you weren't aware, Trek's in-house kit and component brand is Bontrager, so it's no surprise to find this adorning the Émonda throughout. The Comp VR-C Road is a shallow drop bar with a compact design, making it usable for most riders regardless of flexibility.

2022 Trek Emonda SL 5 Disc - drop bar and lever.jpg

There is nothing flash about it, but it is comfortable, has a decent length of central section for computer mounts or lights, and its aluminium construction is stiff enough for out-of-the-saddle efforts.

> road.cc Road Bike of the Year 2020/21

The Bontrager Elite Stem is another component that just gets on with its job. On the 56cm frame you get a 110mm, and it comes with Trek's Blendr compatibility.

2022 Trek Emonda SL 5 Disc - bars 2.jpg

This means you get a selection of mounts for various accessories, such as lights and computers, to sit out in front of the stem. On Trek's website it's £59.99 (£30 more than the handlebar), so it's certainly not a budget component.

2022 Trek Emonda SL 5 Disc - stem.jpg

The saddle is called the Verse Comp and it's a good 'un, at least for me. It's got a swoopy shape I found gave me plenty of different position options (I like to slide back to climb, for instance). It's 270mm long and 145mm wide (155mm on the smaller frames) with steel rails and a central cut-out. It's also compatible with Blendr accessories.

2022 Trek Emonda SL 5 Disc - saddle.jpg

The frame itself is compatible with DuoTrap S, which is a Blutooth/ANT+ sensor which can send all sorts of data and works with Garmin, Bontrager, PowerTap and more, though the sensor is sold separately.

Wheels and tyres

As with the rest of the finishing kit, the wheels are Bontrager. Using their sealed alloy hubs mated to Paradigm SL rims, they have an internal width of 21mm and 24 spokes front and rear. As I mentioned earlier, they are a bit weighty, but they rode well enough throughout the test period, and I had no durability or trueness issues. They are tubeless ready for a bit of futureproofing.

> road.cc's Best Cycling Wheels of the Year 2020/21

I'm a fan of Bontrager's tyres. I've ridden a few, and was impressed when I tested the R3 Hard-Case Lite a couple of years back. The SL 5 uses the entry-level R1 Hard-Case Lite, and it's pretty good. With a 60tpi (threads per inch) casing it isn't the most supple, but it doesn't detract too much from the ride quality.

2022 Trek Emonda SL 5 Disc - tyre and rim.jpg

They roll pretty well too, and grip is more than adequate in both the wet and dry. More importantly though, considering the review period took in the end of winter, they seem robust and suffered no punctures.

Still, as with the wheels the SL 5 deserves better in the long term. If you want to keep things in the Bontrager family, those R3s mentioned retail for £42.99 now, or £52.99 if you want to go tubeless.

Bike prices are all over the place at the moment, and there have been some big jumps in Trek's line-up. That SL 6 Pro I reviewed was £3,350 in 2021, and it's now £3,900 with what looks to be the same build. The frameset has gone up from £2,200 to £2,700. Meanwhile this SL 5 has come through relatively unscathed at £2,750, up just £25 over last year's prices.

Around the time this Émonda was released, Specialized launched its new Tarmac SL 7 (I was lucky enough to review the S-Works model), and it's a similar sort of bike to the Trek. For 2022 Specialized has largely used SRAM components on its road bikes though, so there's no direct comparison with the SL 5.

However, the entry-level Tarmac SL 7 is the Comp model, which comes with a Rival eTap AXS electronic groupset and DT Swiss alloy shallow section wheels for £5,000, while Trek's SL 6 eTap comes with the same wireless groupset and the Bontrager 35mm deep carbon wheels for £4,300.

There is some tough opposition out there though, with Canyon's new Ultimate CF SL 7 Disc featuring a 105 groupset, a full aero carbon cockpit and a claimed weight of 8.2kg for just £2,149.

Giant's TCR Advanced Disc 2 doesn't quite have the aero attributes of the SL 5, but it is considered a very good lightweight all-round race bike. For £2,349 you are getting a 105 groupset, full carbon frameset and Giant's own alloy wheels.

The Émonda SL 5 is a great bike to ride, and that's down to the top-notch frame and fork paired to good quality finishing kit. True, the wheels and tyres can take the shine off of the performance a touch, but that is true of many entry-point bikes. This is a bike that will tackle any kind of topography or race and excel at it. The frameset is great and it's ripe for upgrades over time too.

The Émonda is a classic all-rounder, fun, fast and stiff, although this model isn't the lightest

Tell us what the bike is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about the bike?

Trek says, "Émonda SL 5 Disc is a lightweight carbon road bike with a balanced ride quality, superior handling characteristics and the added benefit of free speed thanks to aero tube shaping. It's a great choice for century rides on hilly terrain, windy flats and speedy descents."

I think the SL 5 is a classic all rounder.

Where does this model sit in the range? Tell us briefly about the cheaper options and the more expensive options

This SL 5 model kicks off the SL range, sitting just £25 above the price of the frameset. Going up through the models you find the SL 6 and SL 6 Pro (£3,400 and £3,900 respectively), the SL 6 eTap (£4,300) and the Ultegra mechanical SL 7 (£5,350). Finally you get to the 12-speed Ultegra Di2 SL 7 (£5,600) and the SL 7 eTap, which uses SRAM Force for £6,100.

Above the SL range is the SLR line up, and below you'll find the aluminium alloy range, the ALR.

Tell us about the build quality and finish of the frame and fork?

A high quality frame and fork. It feels great to ride and the paint finish is high end.

Tell us about the materials used in the frame and fork?

Frame: Ultralight 500 Series OCLV Carbon, Ride Tuned performance tube optimisation, tapered head tube, internal routing, DuoTrap S-compatible, flat-mount disc, 142x12 mm thru axle

Fork: Émonda SL full carbon, tapered carbon steerer, internal brake routing, flat-mount disc, 12x100 mm thru axle

Tell us about the geometry of the frame and fork?

With its steepish angles and short wheelbase, this sits very much in the race bike camp.

How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?

This 56cm model features a stack of 563mm and a reach of 391mm, which is fairly typical for a bike of this size with racing intentions.

Riding the bike

Was the bike comfortable to ride? Tell us how you felt about the ride quality.

It has a firmer ride than a lot of carbon frames, but personally I like that. It feels like a purposeful and aggressive frame without ever feeling harsh and uncomfortable.

Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?

Plenty of stiffness throughout, most notably at the bottom bracket junction.

How did the bike transfer power? Did it feel efficient?

It does feel efficient, especially considering its weight.

Was there any toe-clip overlap with the front wheel? If so was it a problem?

How would you describe the steering? Was it lively neutral or unresponsive? Responsive.

Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?

I found the handling quick with a degree of balance to it – it never feels twitchy.

Which components had the most effect (good or bad) on the bike's comfort? would you recommend any changes?

I liked the Bontrager saddle. I found it squidgy enough to absorb the bumps, without being so soft you find yourself bouncing around.

Which components had the most effect (good or bad) on the bike's stiffness? would you recommend any changes?

The stem and handlebar offer stiffness to match the frame, and there's no real sign of flex from the wheels either.

Which components had the most effect (good or bad) on the bike's efficiency? would you recommend any changes?

The wheels are a bit weighty, so if you can upgrade to something lighter you'll really unlock the performance of the Émonda.

The drivetrain

Tell us some more about the drivetrain. Anything you particularly did or didn't like? Any components which didn't work well together?

Performance-wise, 105 is probably all the groupset most of us will ever need from Shimano's catalogue. The shifting is great, as is braking power and modulation, and the value is good.

Tell us some more about the wheels.Did they work well in the conditions you encountered? Would you change the wheels? If so what for?

The Bontrager wheels are decent enough. They blunt the SL 5's climbing and acceleration a touch due to their weight, but I can't fault their durability.

Tell us some more about the tyres. Did they work well in the conditions you encountered? Would you change the tyres? If so what for?

Bontrager tyres typically offer decent performance, and so it is with the R1s. Like the wheels though they are a touch heavy and not the most supple.

Tell us some more about the controls. Any particularly good or bad components? How would the controls work for larger or smaller riders?

Good quality in-house kit. Upgrade if you want some bling, but there's no real need.

Your summary

Did you enjoy riding the bike? Yes

Would you consider buying the bike? Yes

Would you recommend the bike to a friend? Yes

How does the price compare to that of similar bikes in the market, including ones recently tested on road.cc?

This is well priced against a similar model in Specialized's Tarmac line-up, as mentioned in the review. There is tough opposition from the likes of Giant and Canyon, though.

Use this box to explain your overall score

The Émonda SL 5 is a very likeable bike; it has a solid dependable feel while still maintaining plenty of fun factor. There is some tough opposition out there price-wise, but would I feel shortchanged by the Trek? No. It has a quality ride feel and a quality build, and I enjoyed every mile I covered on it.

Overall rating: 8 /10

As part of the tech team here at F-At Digital, senior product reviewer Stu spends the majority of his time writing in-depth reviews for road.cc, off-road.cc and ebiketips using the knowledge gained from testing over 1,500 pieces of kit (plus 100's of bikes) since starting out as a freelancer back in 2009. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 170,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him, he still likes to smash the pedals rather than take things easy. With a background in design and engineering, he has an obsession with how things are developed and manufactured, has a borderline fetish for handbuilt metal frames and finds a rim braked road bike very aesthetically pleasing!
