Trek likes to keep it simple, stupid when it comes to navigating its road bike range. Madone: that's the aero one. Domane: that's the comfort one. Emonda: that's the lightweight one. Easy-peasy.

The Emondas are then divided up into the aluminium ALR and the S, SL and SLR carbon fibre frame platforms, getting progressively lighter and – because this is the way things generally work – more expensive.

Coming in at 8.55kg (18.8lb), the Emonda SL 5 is light but it doesn't feel like Trek has filled the tubes with helium (the frame weight is a claimed 1,091g, size 56cm). The Merlin Nitro SL (£200 more expensive at £1,999.99) that we reviewed back in the summer hit the scales at 7.7kg (17.0lb), for instance, while the Boardman SLR Endurance Disc 9.0 (also £1,999.99) we tested was 8.2kg (18.2lb).

Don't get too hung up on weight, though. I only really bring it up because Trek makes such a big deal of it when talking about the Emonda. Climb aboard the SL 5 and it immediately feels alive, responding keenly as soon as you turn the pedals. Put a serious amount of power through the cranks and it springs forward as if it was just waiting for the flag to drop. Both the head tube and the down tube are enormous, holding the frame firmly in shape when you're recruiting every muscle fibre on an out-of-the saddle sprint or climb.

Relaxed but performance-orientated

Speaking of climbing, the Emonda SL 5 is fitted with a Shimano 105 compact chainset (50/34-tooth chainrings) which, matched to an 11-28 11-speed cassette, provides enough low gears to get you up the steep stuff in relative comfort. All of the other Emonda SLs are fitted with compact chainsets too, by the way, and they all come with frames built to Trek's H2 fit. That requires an explanation and, as luck would have it, there's one coming along right now... While Trek's H1 fit puts you into a low, flat-backed, aggressive riding position, H2 is a little more relaxed, although it's still performance orientated.

I have the 58cm Emonda SL 5 here with a 57.3cm effective top tube, a 55.3cm seat tube and a 19cm head tube. The stack height is 596mm and the reach is 391mm.

With an H1 fit (the Emonda SLR Race Shop Limited frameset is available in H1) the reach is a little longer (400mm) and the stack is quite a lot lower (567mm). You all know what reach and stack are... (no? stack is the vertical and reach the horizontal measurements from the centre of the bottom bracket to the top of the head tube).

Don't get the impression that the Emonda SL 5's H2 fit will have you sitting bolt upright in the saddle because it's a long, long way from that. For comparison, a 58cm Domane SL 5 has a stack height that's 15mm higher and a reach that's 11mm shorter. In other words, the H2 fit sits somewhere in the middle, an Aristotelian golden mean. Or Goldilocks' favourite porridge, if that's a cultural reference that works better for you. Put simply, a lot of people will get on well with the fit because it requires less flex in the back and neck than a traditional race fit without binning off the idea of efficiency.

One aspect of the Emonda SL 5's ride that surprised me is the level of comfort on offer here, particularly for a performance bike with 25mm-wide tyres. Okay, you don't get a clever IsoSpeed decoupler like you'll find on a Madone or a Domane to cushion the ride, but there's a decent amount of give in the seatmast and cap that Trek provides instead of a more traditional seatpost, and in the flattened, ultra-skinny seatstays.

As we all know, saddles always come down to personal preference – what feels like an armchair to one person can feel like a razor blade to another – but the steel-railed Bontrager Montrose Comp specced here has a pressure-relief channel/hole in the centre and loads of flex in the shell so I imagine it'll make more friends than enemies.

Great groupset

The Emonda SL 5 descends with assurance, giving you the confidence to lay off the brakes when others are nervously feathering theirs. When you do need to slow down the Shimano 105 brakes work on the alloy rims to provide plenty of predictable power. Shimano does make very good brakes. These are of the direct mount variety and they can be relied upon to hold tight when you need them. They even put in a decent performance in damp conditions although, like any rim brakes, they're outperformed by disc brakes when it's properly wet. If that bothers you and you can stretch to £2,650, the Emonda SL 6 is available in a disc version – with 12mm thru-axles front and rear, a Shimano Ultegra groupset including flat mount hydraulic discs, and an 11-32t cassette.

As well as the brakes, the SL5's shifters, derailleurs, chainset, cassette and chain are all Shimano 105. We've covered this groupset a million times on road.cc and it really is difficult to fault for the money.

I particularly like the light action shifters. They're slim, comfortable and easy to operate from either the hoods or the drops. There's not a massive difference between these and more expensive Ultegra, or even top of the pile Dura-Ace mechanical shifters. Sure, you can tell them apart but in use... puh! I'd happily use 105 on every ride. It's amazingly popular and rightly so. Although a couple of others run it close, 105 is still arguably the best value groupset out there.

> Head to head: Shimano 105 vs Shimano Ultegra

> And: Shimano Tiagra vs Shimano 105

This has all been a bit of a lovefest so far, but my one tiff with the Emonda SL 5 was right at the start of our relationship. I picked up the bike and was riding home from the office on it – five miles in, whistling a happy tune, thinking about what I'd have for tea, you know the sort of thing – and the front end started to feel... odd. I got out of the saddle on a climb and it felt decidedly spongy. Weird!

I stopped to check everything and it turned out that several spokes had loosened – about eight of them, I think. And I mean that they'd really loosened to the point that the nipples were just about holding on by their fingertips (shut up! Of course they do). My multi-tool has a spoke wrench on it so I tightened them up at the side of the road, then did a proper job when I got home. Since then the wheel has been fine.

I've reviewed loads of Treks before and this hasn't been an issue in the past, so I'm happy to put it down to bad luck. To be honest, if you know which way up to hold a spoke wrench it's not a massive problem, but it would be a pain if you had to book your bike in to a shop and have a mechanic do the fettling for you. Anyway, I've forgiven the Emonda SL 5 for that now and we've both moved on.

Spoilt for choice

The Emonda range is large, kicking off with the Shimano Tiagra-equipped ALR 4 at £1,000 and going right up to the SLR 9, with Shimano Dura-Ace Di2 components, at £8,500 (a customisable Project One version of the Emonda SLR 9 is also available).

There are four SL models ranging in price from £1,500 (SL 4, Shimano Tiagra) up to £4,300 (SL 7, Shimano Ultegra Di2). At £2,000, the Emonda ALR 6, with an aluminium frame, is actually more expensive than the SL 5 courtesy of a next-level-up Shimano Ultegra groupset. The SL 5 is also available as a women's model.

Oh, and you can buy an Emonda SL frameset for £1,350 – but why would you do that when you can get a complete Emonda SL 4 for £1,500?

> Check out our guide to Trek's 2018 road bike range here

As well as the Emonda SL 6 Disc mentioned earlier, there's an Emonda SL 7 Disc, equipped with a Shimano Ultegra Di2 groupset and Bontrager Aeolus Pro 3 Tubeless Ready wheels, for £4,400.

You can certainly get complete bikes with carbon fibre frames and Shimano 105 components considerably cheaper than the Emonda SL. The Focus Izalco Race Carbon 105, for example, is £1,399 and Giant's TCR Advanced 2 is £1,449. Those two are killer value. Equally, there are plenty of carbon/105 bikes out there that are more expensive. Cervelo's R2 105 is £2,199, for example, and BMC's Teammachine SLR02 Two is £2,250.

I would say that you're getting an extraordinarily good frame with the Trek Emonda SL 5 – one that'll handle considerable upgrading if you fancy doing that gradually as and when individual components wear out. It's that which makes this bike such impressive value for money.

Overall, the Trek Emonda SL 5 is excellent. I had an early issue with one of the wheels but that doesn't detract from the fact that this is a fast and nimble road bike that reacts like something considerably more expensive. Also comfortable and well behaved, it makes you question whether it's worth spending any more money than this.

Tell us what the bike is for

It's a road bike designed for racers and other performance-type riders who are interested in speed and fitness.

Frame and fork

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

The quality is exceptionally good throughout.

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

The frame is made from Trek's 500 Series OCLV carbon fibre. The fork is carbon too.

Tell us about the geometry of the frame and fork?

Like all the Emonda SL frames, this bike is built to Trek's H2 geometry which sits somewhere between a low and stretched H1 fit and a more upright endurance setup. H2 is certainly performance-focused, it's just not as aggressive as H1.

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

It's about what you'd expect.

Riding the bike

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

It's surprisingly comfortable for a bike of this type. You only get so much cushioning from 25mm tyres but the seatmast certainly helps to damp vibration and soften the blows.

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

The super-wide down tube holds the bottom bracket firmly in place and the tapered (1 1/8in to 1 1/2in) head tube keeps the front end in order.

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

It felt efficient, without a doubt.

Was there any toe-clip overlap with the front wheel? If so

Some. It's only ever an issue for tight manoeuvres at walking pace.

How would you describe the steering? Was it lively Lively.

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

It offers a great ride whether you're going uphill, downhill or on the flat. It's a well-balanced bike that feels like it can cope with pretty much anything.

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

The seatmast and seatmast cap take some of the credit here, along with Bontrager's saddle.

You can swap to 28mm wide tyres if you want to run lower pressures for more comfort.

The drivetrain

Wheels and tyres

I have to take into account that several spokes came loose almost immediately. The rims are tubeless ready, if you want to go down that route.

After an initial scare they were fine.

Anything else you want to say about the componentry? Comment on any other components (good or bad)

The Shimano 105 groupset put in an excellent performance.

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

Use this box to explain your overall score

The Trek Emonda SL 5 puts in a really strong performance. You'd be hard-pressed to tell from riding it alone that this wasn't a considerably more expensive bike. You're getting an exceptionally good bike for the money, and that equates to a 9.

Overall rating: 9 /10

I share similar thoughts on Emonda SL 5. Bought new in 2019 as 2018 model for only 1.200 € and it seemed like a great deal. But wheels almost fell appart after 30 km, most of the spokes were totaly loosened. I was lucky to find that out just before the fast descent. Both wheels, front and rear! I took it to dealer and they said I was just unlucky, one in a million. Then I waited more than 2 months for new pair of wheels, replaced under guarantee. Got Bontrager Affinity TLR wheels. They were fine but bearings seem to be totaly destroyed after about 7000 km. So I did upgrade to Mavic Cosmic.

What do I think about the bike now? It is a great bike, with perfect geometry for me, very responsive and good for climbing. Not super light but good enough. Not aero at all but new wheels are doing the job much much better. It's a climber not a TT bike. Would I recommend the bike to anybody? Probably not, due to the serious issue with wheels that could affect safety. 

I still cannot understand how can a company like Trek put so awfull wheels on a nice carbon bike like Emonda 5. In my eyes this was a recall situation and obviously not a one in a million case.

I might be corrected but up to last year or perhaps this, the model was fitted with lighter 'Race' wheels.  They kept the price at £1800 and put cheaper wheels on it.  It's a shame as the frame and groupset is excellent, in my opinion.

  "Coming in at 8.55kg (18.8lb), the Emonda SL 5 is light...

   Don't get too hung up on weight, though. I only really bring it up because Trek makes such a big         deal of it when talking about the Emonda".

How does a carbon bike which sells for £1800 and weighs over eight and a half kilos get described as LIGHT ?

For comparison at £1800:  the Canyon Endurace CF8.0 is size Medium is 7.2 kilos.

The £1800 Rose GF Team 4 Ultegra is 7.1 kilos.

Both bikes have a complete Ultegra groupset - no sneaky substitutions, both have excellent DT Swiss wheels and are well equipped right down to Conti's top tyres.

What they seem to lack (apart from a kilo and a half) is the word Trek written down the side.

If the original article was from 2014 when the SL5 was launched, then 8.55 Kg would have been viewed as somewhat light for a fast endurance bike back then.

"If the original article was from 2014 when the SL5 was launched, then 8.55 Kg would have been viewed as somewhat light for a fast endurance bike back then".

     All true, although the article is bylined:

                   by Mat Brett May 25 2018  

    and a quick check of the Evans website suggests the bike is still nearly eight and a half kilos.

Unlike the German bikes this bike does come with boat anchors for wheels and wire bead tyres. Along with the 105 groupset that would explain most of the weight difference.

The review suggests though that the frame is fantatsic so a wheel + tyre upgrade would leave you wth a fantastic bike. Sure it would cost more than the German bikes but there's more to a bike than just it's weight.

European reviews of the Rose & UK and European reviews of the Canyon suggest the frames on both those bikes are excellent too. So the question is: do you want a lightweight bike with an excellent frame, a complete Ultegra groupset, highly regarded DT Swiss wheels and top drawer finishing kit... or do you want the Trek.

Or you could take the view that a bike is more than just a frame, a groupset, wheels, tyres and finishing kit in which case the big American brands with their overweight, under specced and overpriced offerings are for you.

"Updated May 25th  2018". It was a recycled article, hence my comment......

Why is this bike being compared to the  Boardman SLR Endurance Disc 9.0? The calliper version comes in at 7.6kg and gives you an almost complete Dura-Ace groupset and a better wheelset for only £99 more.  https://www.boardmanbikes.com/gb_en/products/242-slr-9.2-endurance.html

Did a few hundred KMs on a rented SL5 in Mallorca earlier this year.

Nice machine, although the most impressive element was the 105 groupset (especially the brakes), which is easy to find on other makes/models.

It was definitely comfortable, and reasonably light - although I couldn't say I noticed a huge improvement on my 725-framed Equilibrium. May be my own frame which means a couple of KG off the bike doesn't make much obvious difference, of course...

So certainly not a bad option but I'd be tempted to look around a bit more before splashing that sort of cash.

Decent / good frame with full 105, own brand everything else (bars, stem, seatpost, wheels, tyres, may be ok stuff) inc wheels which look very spokey. 

giant tcr advanced pro 2 would be a potentially better bike

in a sale at £1800 it has giant tcr frame (one of stiffest on market) giant slr carbon wheels and 105.

beaut bike would reccomend. Its weight is also 7kg

Well that's very reassuring.

Incredibly generous considering the wheel supplied was in a dangerous condition.

An ordinary person may not have noticed the odd feeling and ridden it until it collapsed under them, throwing them under a car. It’s pretty serious.

Well that really depends, for most people that would have been picked up by the shop you purchased the bike from. For everyone who orders it direct I would expect them to check the wheel before riding it

Really? They'd notice the wheel not fitting between the brake pads a long time before collapsing.

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.

Now With Aero

The new Émonda gets a major drag reduction with a tiny weight gain.

Simple Seat Mast

The seat mast has lots of adjustment range, and an easy-to-use saddle clamp.

Light and Slippery

The new Bontrager Aeolus RSL 37 wheels are light, sleek, and stable.

Wide and Threaded

The T47 bottom bracket has a wide stance, and user-friendly threads.

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

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’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.

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.

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.

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.

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.

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.

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.”

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.”

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.

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.

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.

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).

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.

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.

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.

2021 Trek Emonda SL 6 Pro review

Trek's climbing specialist has been re-imagined as a do-it-all race bike.

Felix Smith / Immediate Media

Amazingly stiff ride; race-ready long and low fit; exceptionally fun to ride.

25mm tyres exaggerate harsh ride and harm performance on imperfect road surfaces; weight isn't competitive for price.

The new 2021 Trek Emonda sees a shift away from a purely climber-focussed bike to a more all-round package with the de-rigueur aero shaping to match.

We have two bikes in for review. My colleague, Warren, has the top-end 6.9kg Emonda SLR 9 model with all of the bells and whistles, and an outrageous £9,700 price tag .

I have been testing the Ultegra R8000-equipped 2021 Trek Emonda SL 6 Pro.

The SL-level Emonda is based on Trek’s OCLV 500 carbon layup, which adds roughly 445g to an unpainted frameset in an unspecified size compared to the top-end model.

You do, however, get the exact same geometry and frame shape as the SLR-level Emonda, so the differences should largely boil down to weight alone.

More on the new Trek Emonda

• Trek Emonda SLR 9 eTap first ride review

At £3,350 ($3,799 / €3,799 / AU$5,499), the SL6 Pro is by no means cheap, but represents fairly good value for money in the context of the wider market

For that cash, you get a full Ultegra R8020 groupset , a Bontrager Aelous Elite 35 carbon wheelset, a perfectly inoffensive alloy cockpit and a very plush Bontrager saddle. The bike weighs 8.13kg on the nose with no pedals.

Picking two comparable bikes, the Giant TCR Advanced Pro 2 Disc costs roughly the same (£3,499) for a broadly similar build, as does the Rose X-Lite 6 (~£3,450).

Trek has significantly altered the geometry of the Emonda for 2021, and it is now only available in the brand’s middle-of-the-road H1.5 fit.

H1.5 sits pretty much in the middle of Trek’s super aggressive H1 geometry and its endurance-focussed H2 fit.

The resulting shape strikes a nice balance between real-world usability while allowing the sportier riders among us to get a low and fast setup should they so wish.

The stack for the new Emonda is on the lower end of the spectrum for a 56cm bike at 563mm. The reach is fairly average, at 391mm for a 56cm bike. The 56cm bike ships with a 100mm stem.

While the reach of the frameset is fairly average, when matched with the 42cm-wide Bontrager Elite VR-C bars, which have a hefty 100mm reach, the fit of the bike feels suitably long and low.

I really like the overall profile of these bars – there’s loads of room in the drops so you can actually spend some time down there comfortably without your hands getting smooshed up, and the extra reach offers additional useful hand positions.

Adding reach to the bars (rather than increasing the length of the stem) also means the tops stay a touch closer to you, giving a really comfortable position for seated climbing.

The ride of the bike is exceptionally stiff and incredibly fun in the way that a proper race bike can be.

It’s got that addictive ultra-efficient feel with a totally unyielding pedal response that is amazing on the climbs – you are giving up nothing to the frame when mashing yourself into a lactic oblivion.

I dare say the overall feel is almost a little old school, with a super stiff ride that’s reminiscent of early carbon bikes.

This will be polarising for some riders, but I personally really like it. It feels properly rapid and responsive, and going fast is never not fun.

While perhaps divisive, this super stiff ride also goes some way to differentiate the bike from the others in Trek’s lineup.

The line between the Emonda and Madone – and to a certain degree, the Domane – is now fairly blurred with this new bike.

But by keeping it simple, with no ISOSpeed squashiness, a racy ride and a lighter overall package, the Emonda stands out in the range.

That stiffness also translates into a really engaging and fun ride on the descents. The bike shrugs at irresponsibly heavy braking into corners, remaining accurate and giving – yes, I really am going to say it – a really feedback-rich ride. It’s a total hoot.

It’s no surprise that this stiffness results in a firm ride.

It’s not a rough ride, per se – the bike still provides that pleasingly damped feel that any quality carbon bike gives on imperfect surfaces, and the integrated seat mast brings a degree of rear end comfort.

However, on larger bumps, the front end can feel quite jarring. The alloy bars will contribute to this, but the stock 25mm tyres are the main culprit.

25mm wide tyres were considered progressive a few short years ago, but the majority of new road bikes these days ship with 28mm tyres (or even larger) and not without good reason.

Wider tyres have consistently been shown in testing to have lower rolling resistance than narrower tyres and, as they can be run at lower pressures, they also improve comfort. Being more comfortable means less fatigue, which means increased speed.

This is well-trodden ground, so to see 25mm tyres here is a little bit disappointing – other bikes in the Emonda range feature 28s, and I’ve always admired Trek for boldly speccing 32mm tyres on the Domane, so to see narrower rubber here feel like a bit of a cop-out.

Trek is clearly trying to pander to the hill climb kids with the tiny reduction in weight 25s will offer, but 28s would be better for the majority of riders in nearly all situations.

Keen to see how much of a difference wider tyres would actually make, I swapped the stock Bontrager R2 Hard-Case Lite tyres in favour of a pair of Panaracer Race D Evo tyres. These measure bang on 28mm when inflated to 70psi on the Bontrager Aeolus Elite 35 wheels.

Unsurprisingly, the wider tyres smoothed out the ride of the bike significantly without making the ride feel mushy – you can focus on getting the most out of the bike’s stiff frameset without having to worry so much about potholes or broken road surfaces. The larger tyres also improve grip on descents.

They also make very light gravel detours a more appealing possibility.

Gravel riding is absolutely one bazillion per cent not within the intended remit of this bike, but the larger volume tyres make short stretches along smooth unsealed rail trails or rough access roads a much less hateful experience.

On a similar theme, I was also a little disappointed to see the bike come set up with tubes.

The likes of Giant are now shipping complete bikes tubeless out of the box and, regardless of which side of the tubeless vs. tubed debate you sit on, including tubeless tech as stock adds value to a bike.

Given the new Aeolus 35 Elite wheels are tubeless-compatible, it’s disappointing that the included tyres aren’t at least tubeless-ready.

As mentioned, the bike has been doused in a liberal helping of aero sauce, and the new bike is claimed to sit between the outgoing Emonda and the Madone in terms of aero performance.

There’s no way I can quantify these claims, but the bike does feel fast on the flats. I suspect that has more to do with the fact the bike’s geometry means it’s possible to get into a properly long and low position, so I’ll leave it up to you to decide whether you believe Trek’s claims – or whether you care.

Not that it has any bearing on performance, but the aero shaping has resulted in a bike that looks fast. I’m fond of the overall shape of the bike and I’m glad to not see dropped seat stays here. The lines are classic and the traditional cockpit doesn’t look out of place either.

Trek clearly doesn’t want you to forget you’re riding one of its bikes judging by the sheer size of the logo on the down tube. It is so over the top and a bit daft, but I kind of dig it – it’s like a postmodern statement, the David Byrne big suit of bicycle logos .

I also think the paint job looks really nice for what is, in the context of this model range, a ‘budget’ bike.

A surprising standout from the bike is the Bontrager Aeolus Comp saddle.

Every man and his dog has thrown his hat into the short nose and stubby saddle game, and I’ve tried a fair few now, but I think it’s a toss-up between this and the Pro Stealth Superlight for my all-time favourite .

Trust me when I say this is very high praise because I love the Pro Stealth. The Aeolus is squashy, comfortable and perfect for my peach. I can’t believe it has taken this long for saddles to get this good.

The bike is built around a full Shimano Ultegra R8020 groupset . It’s nigh-on impossible to level criticism at R8000, offering nearly all of the performance of Dura-Ace at a considerably lower price point.

The 52/36 crankset is paired with an 11-30 cassette. For a go-fast all-round climb-friendly bike, this is perfect.

However, it’s worth noting that the bike is equipped with a short cage mech, which officially limits the drivetrain to a 30t cassette. This means you would have to go for a smaller set of chainrings if you require lighter gearing.

Even so, the gearing has more than enough range to climb comfortably in the saddle on most climbs.

The SL6 Pro is the ‘cheapest’ bike in the new Emonda range to feature carbon wheels.

At 35mm deep, the Aeolus Elite 35 should, in theory, give a bit of aero advantage without sacrificing too much on the climbs in terms of weight.

A 35mm wheel is unlikely to present serious problems in crosswinds, and they feel perfectly well-mannered and stiff. The wheels are based on DT Swiss’ Ratchet EXP freehub, which are easy-enough to service with widely-available spares.

Again, I’m a bit miffed these aren’t set up tubeless out of the box. It would allow you to run lower pressures, improving comfort and grip, which is never a bad thing.

2021 Trek Emonda SL 6 Pro conclusion

Make no mistake – the Emonda is an uncompromising race bike, and it’s all the better for it.

In a world of squashy do-it-all bikes, the Emonda’s wonderfully moreish super stiff ride stands out and I’ve really enjoyed my time testing it.

Speccing standard 25mm clincher tyres in 2020 is an odd move, and the weight for this particular build isn’t that competitive.

You also lose out on some (claimed) aero benefit with the standard cockpit versus the fancy new integrated Bontrager Aeolus RSL VR-C bar-stem combo. But, if you’re anything like me and enjoy endlessly tweaking your position and cockpit setup, this might not be such a bad thing.

Jumping up to the Emonda SL 7 (£4,850) would get you an Ultegra Di2 groupset, Bontrager Aeolus Pro 37 wheels and the integrated cockpit, but I’m not convinced the extra expense would be worth it.

A few small spec niggles aside, if you’re after a delightfully fun go-fast race bike, the 2021 Trek Emonda SL 6 Pro is very unlikely to leave you wanting.

That 52 looks too small to me.  

Legendary Member

The 52 looks too small for you by some distance. It would be a mistake, IMO, to buy it.  

Slippery scientist

You said the 54 had pedal reach issues - surely not with the saddle slammed to the frame? Obviously you wouldn’t want that anyway but I’d guess there would be enough seat post adjustment to get the leg length where you want it? Once that’s set then deal with reach, remembering you can adjust the saddle fore and aft as well as the height of the stem (assuming there are some spacers under it) and even a different stem if needs be. I wonder if the 52 uses shorter crank arms than the 54?  

sort of need a pic on the 54, but given you have a long body, you can cope / need with the extra top tube length, so my normal advice would be to size down if in bewteeen, but on this occasion i'd say size upto the 54. when you say your legs didnt seem long enough - as long as you can get the seat low enough (it has a sloping top tube) to suit your leg length then it will be fine. you just will have less seat post showing than a long legged short body person would  

Still rolling along

Arrowfoot said: Bike looks small. You are sitting more vertical rather than horizontal and your chin is already over the head tube. The stem extension is not the answer. The rider below has a more horizontal posture and notice where his chin is. I would go for the 54 due to longer top tube and lower the seat post. View attachment 596917 Click to expand...

All uphill said: My first thought too, is that you may need shorter cranks than standard. 170mm or even 165mm may help you with your relatively short legs. Click to expand...

• Size: 50, 52 - Shimano 105 R7000, 50/34 (compact), 170 mm length
• Size: 54, 56, 58 - Shimano 105 R7000, 50/34 (compact), 172.5 mm length

I’d steer clear of proprietary seat masts at all costs. Always seem to have potential for problems (like not being able to put the seat load enough!)  

vickster said: Can you try the 52 with the longer stem? Or get lifts in your shoes? or maybe it’s just not the right bike frame for you? Click to expand...

That’s pretty rubbish if they won’t given the spend and having suggested it. It’s a 5 minute job. I’ve certainly had bike shops change stems and saddles for test rides (and had no issue when I didn’t buy in the end!)

If you really want to be racey a 120mm stem on that could work. All the pros deliberately size down to save weight & you can still stretch out & get low.

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

'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.'

'It's an incredible update from Trek.'

'The updated Emonda packs one hell of a punch, and Trek has a winner on its hands. The integrated cockpit is nice and all, but the real win is the H1.5 fit, which makes the Emonda feel more stable while maintaining the aggression and responsiveness of previous Emondas. That, coupled with a lightweight construction, comfortable ride and aerodynamic shaping, brings Trek's top-of-the-line climber from a very good bike to an excellent one.'

'The Emonda is still light, and it’s still stiff, but now there’s an extra dose of free speed.'

'Overall, Trek has done a solid job here of updating the Emonda, infusing meaningful improvements in several key areas, but without breaking the basic formula that has made the bike so popular.'
