Documents showed last week Trek’s 2021/2022 Emonda SLR and 2022 Speed Concept SLR bikes, and aftermarket carbon handlebar/stems, can potentially crack. Now, the brand makes the recall official in the U.S.

Trek is voluntarily recalling every existing 2021 and 2022 Emonda SLR and 2022 Speed Concept SLR bike, in conjunctionwith the U.S. Consumer Product Safety Commission (CPSC). The recall results from concerns that the various carbon components could fracture if overloaded.

It follows a recall for the same problem for bikes sold in Australia. To date, Trek has received 37 reports of broken carbon handlebars, and one report of injury resulting in scrapes and bruises, according to the recall.

The recall impacts about 3,730 bikes and 1,015 cockpit setups in the U.S. and Canada. Trek is offering free repairs and store credit for those impacted, per its recall .

Trek Recall: Carbon Bikes, Components

Affected parts include the base bar on the Speed Concept SLR   aero bike and the Bontrager Aeolus RSL VR-C integrated cockpit on the high-end Emonda SLR road bike.

Affected bikes sold at stores nationwide and online at trekbikes.com , and other online retailers from May 2020 through June 2022. Speed Concept SLR bikes retailed for $8,800-13,500, while Emonda SLR bikes cost $6,700-13,000.

Notably, Trek also made the integrated cockpit available as an aftermarket option in the lineup from model years 2020-2022. The Bontrager Aeolus RSL VR-C handlebar/stem retailed for about $680.

Trek said that if the carbon cracks during a ride, the rider could lose control of the bicycle and fall . If your bike is part of this recall, Trek advises customers to immediately stop using the affected bikes, or any bike with the affected Bontrager Aeolus RSL VR-C handlebar and stem, and bring it into an authorized Trek dealer for a free repair (details below).

Affected models reportedly include:

• All model year 2022 Speed Concept SLR bicycles, including Project One and stock bicycles in any colorway
• All model year 2021 and 2022 Emonda SLR bicycles, including Project One and stock bicycles in any colorway
• Aftermarket Bontrager Aeolus RSL VR-C handlebars/stems

If you’re not sure whether your bike falls under the recall, Trek’s advice is to take it to a Trek retailer for a free inspection.

Recall Repair Details

In its recall , Trek said it will provide customers — through an authorized Trek retailer — the following:

• For Speed Concept SLR bicycles, Trek will provide a replacement base bar, new bar tape, and installation.
• Trek will provide an individual handlebar and stem until an updated handlebar/stem combo is available and new bar tape. These are free and are the customer’s to keep.
• The retailer will notify customers when the updated handlebar/stem combo is available for installation.

In addition, when owners bring their bicycles to a Trek retailer for repair, Trek will furnish a $100 in-store credit that can be used toward any Trek or Bontrager merchandise. The credit is good through December 31, 2022, and has no cash value.

Trek advises Emonda and SpeedConcept SLR owners to stop use immediately amid Aelous RSL VR-C bar recall

The American manufacturer issues a recall of various 2021 and 2022 models following crack fault in Aelous carbon base bar

Trek Bicycle announced yesterday afternoon an immediate recall of all 2022 Speed Concept SLR bicycles, 2021-2022 Emonda SLR bicycles, and aftermarket Bontrager Aeolus RSL VR-C handlebars/stems.

These top-tier models are among those used by the Trek-Segafredo racing team. Women's road World Champion Elisa Balsamo rides a bespoke Emonda SLR with rainbow detail, while the men's team, including Mads Pedersen and Toms Skujiņš, used SpeedConcept bikes for the individual time trials at this year's Tour de France . 

The recall advice, issued from the manufacturer's communications department yesterday, is voluntary, in line with the U.S. Consumer Product Safety Commission.

It has been issued following information regarding the Aeolus RSL VR-C carbon base bar and handlebar/stem, which have reportedly been found liable to cracks if they are overloaded. This represents a danger to riders as if it were to occur during a ride, it could lead to a loss of control and subsequent accidents.

Trek have advised customers to stop using these bicycles – or any bicycles equipped with the Aeolus RSL VR-C handlebars/stems – with immediate effect. 

"Customers should immediately stop using these bicycles or bicycles equipped with the Aeolus RSL VR-C handlebars/stems," the recall advise stated. They are further advised to contact their local Trek retailer. 

Retailers are advised that Trek will provide replacement base bars and free installation for Speed Concept SLR bicycles, and an individual handlebar and stem for Emonda SLR bicycles and aftermarket Bontrager Aeolus RSL VC-R handlebars/stems, until an updated handlebar/stem combo is available.

Check out Trek-Segafredo’s Trek Emonda for 2023

First Published Jan 31, 2023

The Trek-Segafredo men’s and women’s teams will be dividing the vast majority of their time between the Trek Madone SLR aero road bike and this lightweight Trek Émonda SLR in 2023. Let’s take a closer look at the Émonda…

The current Émonda has been around for over two years now – doesn’t time fly? – with Trek calling this incarnation its fastest-climbing bike ever.

> Check out our story from when the current Trek Emonda was launched

The Émonda has always been the lightweight road bike in Trek’s range, but the US brand also focused on aerodynamics in the development of the latest model. 

> Trek releases radical Madone SLR, its “fastest road race bike ever”

The designers say they spent most time working on the front end of the bike – the bar/stem, head tube and down tube – because that’s where you can make most aero gains, testing both with and without a water bottle in place.

Trek says that the flagship Émonda SLR platform is 60 seconds per hour faster than its predecessor on flat roads – in other words, on the older bike it would take you 61 minutes to ride as far as you could in 60 minutes on the newer one – and 18 seconds per hour faster on an 8% gradient (Trek’s notional rider upon which these figures are based is 70kg and puts out 350 watts for the hour). 

Trek says that the Émonda SLR isn’t as aerodynamically efficient as its Madone platform but that it's marginally ahead of the Domane endurance bike.

Using deep-section tubes adds weight over round tubes so the current Émonda SLR that Trek-Segafredo riders use is slightly heavier than the previous model, but the frame still comes in under 700g. The designers say that the slight weight penalty is still worth it for the net gain in speed in most circumstances thanks to improved aero efficiency.

In order to hit its weight, strength and stiffness targets for this bike, Trek says it had to use a new kind of carbon fibre within the layup – which it calls 800 Series OCLV carbon.

Trek isn’t keen on giving away too many secrets but says that from a fibre-type perspective, OCLV 800 is 30% stronger than the material it uses for its OCLV 700.

Trek-Segafredo riders use handlebars, stems, seat posts and saddles from Trek’s in-house Bontrager brand.

The bar and stem are separate units here and the hoses for the hydraulic disc brakes run externally before entering the frame at the top of the head tube.

There are no gear cables or wires to worry about because Trek-Segafredo riders use SRAM Red eTap AXS groupsets with wireless shifting. They also use Quarq SRAM Red AXS Power Meters.

Team riders can choose between 48/35, 50/37, 52/39 and 54/41-tooth chainsets and 10-28 or 10-33 12-speed cassettes.

> Check out our SRAM Red eTap AXS First Ride Review

The wheels are from Bontrager: RSL37, RSL51 or RSL62, depending on the terrain, conditions, and rider preference. The number in the name refers to the rim depth in millimetres. All of these wheels use DT Swiss 240s internals with Ratchet EXP 36-point engagement.

The wheels are fitted with Pirelli P-Zero tyres. The team uses tubeless, clinchers, and tubulars.

The team use Time XPro-10 pedals, Time being a brand that’s now owned by SRAM, and Wahoo Elemnt Bolt and Roam bike computers.

Interesting to see the pro team bikes are sans integrated bars. I know people who have started to get replacement bars from trek after the recall. I decided to keep mine instead of getting the temp replacement but to see the team with a different set up raises eyebrows.

It's possible that the reason is that many pros will use 150-170mm stems with narrow bars, it's not worth tooling up to manufacture the whole assembly for that size, which hardly anyone will buy, whereas it's possibly cheaper/easier to do smaller runs of longer stem & narrow bars separately.

Trek bikes range: which model is right for you?

• Sign up to our newsletter Newsletter

The humble beginning of Trek bicycles took place in the "red barn" - once a carpet warehouse - in Waterloo, USA. The first bikes were steel touring frames , but within three years the brand had expanded substantially.

Eventually outgrowing the barn, Trek moved into a much larger headquarters - still in Waterloo - in the year 1980. From there it began to manufacture road racing bikes, then in 1983 created its first mountain bike before moving into accessories come 1984.

Having started out in steel, Trek moved into developing aluminium bikes in 1985. The first Trek branded full carbon frame came in 1989 - the Trek 5000 had a frame weight of 1.5kg. It was built by an outside manufacturer and discontinued after a year. Trek made its own efforts at carbon, with an in-house production, in 1992 to much greater success.

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

Now, Trek offers the Madone (aero bike), Domane (endurance bike), Emonda (lightweight race bike) and Checkpoint (gravel bike) as well as the Boone cyclocross and Speed Concept time trial machine.

Trek's OCLV Carbon

You can trust Cycling Weekly. Our team of experts put in hard miles testing cycling tech and will always share honest, unbiased advice to help you choose. Find out more about how we test.

Trek's carbon bikes have always used their own patented 'OCLV carbon' - this stands for Optimum Compaction Low Void. It believes this carbon creates the best compromise between low weight and high strength and stiffness.

Optimum Compaction refers to the way sheets of carbon are layered into the mould, and optimised via heat and pressure - in Trek's opinion the two treatments are administered to the perfect ratio. Low Void refers to the minimisation of space between the layers of carbon, which might otherwise reduce strength and durability.

In 1995, Trek opened an independent facility inWhitewater, Wisconsin. The idea being that the Waterloo factory would work in frame development only. For those who want to customise their ride, the'Project One' custom paint programme arrived in 2001.

Trek's pro cycling support

Trek supported now disgraced American cyclist, Lance Armstrong, through his peak years. In 1997, it helped him sign with their sponsored team, US Postal Service Pro Cycling. He won his seven editions of the Tour de Frances on bikes bearing the brand name, but all of said wins were later taken from him following doping violations.

In 2014, the brand sponsored the Trek Factory Racing Team, now calledTrek–Segafredo. In that role, it provided bikes for high profile winners such as Fabian Cancellara and Alberto Contador,as well as Jens Voigt, and notably his Hour Record in September 2014.

In 2020, Trek continued to support the Trek-Segafredo men's and women's race outfits, two highly successful teams.

Trek's acquisitions

Over the years, Trek has made a number of high profile acquisitions. The most famous, perhaps, Gary Fisher bicycles - the mountain bike brand which it took over in 1993.

Later came Bontrager Cycles in 1995 and Electra Bicycle Company in 2014. Bontrager, now Trek's component and apparel brand, maintains the same name as does Electra, the creator of leisure bikes and accessories.

Trek's road bike models

Trek is able to offer a wide range of different bikes, each tuned to a slightly different purpose. Some model families are available in a selection of standards (SLR premium carbon, SL carbon, ALR premium aluminium and AL aluminium), and then these come with assorted levels of componentry to suit your price bracket.

To add even more depth to the range, Trek offers many models in two different 'fits'. The Madone and Émonda come as standard in an H2 (traditional) fit, but there are versions in what it calls 'H1' fit. This is more aggressive, shaving off about 30mm on the head tube to create a longer, lower ride. The Domane comes in an H2 'Endurance' fit, with a few models in 'Pro Endurance', again with a longer and lower stance on offer.

Here's a look at the key model families...

Trek Domane

Our expert review:

Reasons to buy

Reasons to avoid.

The Trek Domane was introduced in 2012. It was created to offer a comfortable ride, the key feature being an IsoSpeed decoupler which separated the seat tube from the top tube, thus reducing vibrations and fatigue.

In 2016 it gained theFront IsoSpeed, which helps to reduce vibrations at the front end without impacting handling. This came alongside a new slider, which alters the level of dampening offered by the rear.

In its most recent update , the Domane took notes from the Madone with an aero fork profile, whilst becoming more versatile thanks to clearance for 38mm tyres (without mudguards, 35mm with). It also gained a downtube compartment for stashing tools (or snacks!).

Though comfort is important to the Trek Domane, it's still a racing frame, and its prowess has been demonstrated by UCI WorldTour riders at major one-day Classics, such as Strade Bianche and the Tour of Flanders. The top Domane bikes come with an H1.5 fit, which was developed with the Trek-Segafredo teams to offer the optimal balance between aerodynamics and endurance.

The Trek Domane - available as a men's build or with women's specific componentry - is a fast selling model, which comes in a range of frame materials.

The Domane SLR uses the lightest carbon Trek offers, the SL is one step down, whilst the AL uses aluminium and is the cheapest of the range.

Trek Madone

The Trek Madone is quite another beast, and the bikes come built for men and women; the latter's models with women's saddles and narrower handlebars . With an aggressive geometry and stiffness to boot, it's a road race hero, and aerodynamics have become part of its lifeblood. When we tested five aero bikes , head to head, the Trek Madone came out fastest.

Modern Trek Madone's feature a high level of integration, with the cables tucked away yet reachable via an access point at the top of the down tube.Wind tunnel testing has helped Trek to create theirKVF (Kammtail Virtual Foil) tube shapes, used on the frame and fork. These unconventional tube shapes are designed to further reduce drag, helping the rider/bike unit to slice through the air efficiently.

Because being bumped around doesn't make you faster, the Madone also features an IsoSpeed decoupler at the seat tube and more recently an adjustable one at the head tube, which offers greater compliance whilst still being integrated to prevent adding drag.

The newest model, according to Trek, can offer 17 per cent more compliance through to 21 per cent more stiffness, depending upon your chosen setting. A damper at the seatpost is also said to cut rebound by 13 per cent. All of these stats add up to a bike that can be comfortable and stiff at the same time - and one that earned a place in our 2018 Editor's Choice awards.

The majority of the bikes come in a more relaxed 'H2' geometry, save for the Madone SLR, which is in an 'H1.5' fit - this is designed to allow riders to achieve an H1 fit or an H2, depending upon their set up.

Trek Émonda

Adding more depth to the Trek family is the Trek Émonda, launched in 2014. Designed to be a climbing bike, newer adaptations are capable of negotiating mixed terrains - with disc brakes available and tyre clearance to 28mm.

>>> Trek Émonda range explained

Trek continues to work on developing the Émonda, dropping the weight of the top end Trek Émonda SLR to 640g in a size 56cm (665g with discs) and 1091g for the Trek Émonda SL (1149g with discs). The weight difference is largely achieved by the use of700 Series OCLV carbon on the SLR, as opposed to 500 series on the SL.

The aluminium model has seen some major work and the result earned it a place in the Editor's Choice 2019 awards. The key characteristic we loved was the way it simply didn't look, or ride, like aluminium. A lot of this is down to Trek's 'Invisible Weld Technology' which increases the surface area of the frame, adding to strength and reducing weight. The ALR model's frame weight comes in at a competitive 1112g, or 1131g with discs, and it uses the brand's 300 Series Alpha Aluminium.

The carbon models are available in 'SLR' build or 'SL', the former being the lightest and the latter more affordable. The majority of Trek Émonda bikes cone in an 'H2' fit, but they can be purchased in an 'H1' geometry, if you choose the top end 'Race Shop' version.

There are a few nods to neatness and integration around, such as the use of 'Blendr Integration' which seamlessly mounts Bontrager’s cycling computer, Ionbike lights or even Garmin computers directly to the handlebars. On SLR versions there's ‘Control Freak Cable Management’ which allows for shifter and brake cables to be housed through the frame.

Trek Checkpoint

With gravel and adventure bikes a fast growing category, the Checkpoint is Trek's offering to fill that sector. The crucial element here is that both the SL and ALR frame options come fitted out with 35c gravel tyres, and can accommodate rubber up to 45c. They've all got internal cable routing, to ensure much stays out, whilst the higher end models use 'Control Freak' routing which is neater.

>>> Best gravel bikes: the top models reviewed

If you opt for the carbon SL model, you get vibration dampening from an IsoSpeed decoupler at the rear, too.  To provide stability and confidence on light trails as well as comfort on all-day adventures, the geometry is not as aggressive as the road bikes elsewhere in the range. Such all-day rides warrant plenty of kit, so there's mounts for racks and mounts. Similar to elsewhere in the range, there's AL, ALR and SL models.

Trek Speed Concept

Trek's Speed Concept time trial bike has been raced by the pros yet is still seen on the amateur race scene as a popular option.

>>> Check out Fabian Cancellara's 2016 Speed Concept

The frames use 500 Series OCLV Carbon, boasting the KVF (Kammtail Virtual Foil) tube shapes described in the Madone, plus a carbon fork with integrated brake and stem - the key goal being cutting through the air quickly.There's space to fit Trek's SC Draft Box and SC Sped Box, largely used by triathletes carrying snacks.

Trek Boone 5

Trek's got plenty of experience in the muddy realm of off-road cycling - and they've got a selection of cyclocross bikes. The Trek Boone 7 model comes with hydraulic disc brakes, a one-by crank and 12-speed cassette and they've all got Bontrager's own 33c cyclocross tyres.

The frame material is Trek's 600 series OCLV carbon, and there's front and rear IsoSpeed decouplers to help riders negotiate the mud without excess transfer of vibration. Combining the mud ready tyres, disc brakes, 'cross focused cable routing and geo into an aluminium package is the Trek Crockett family.

They key differentiation is the frame material, which is300 Series Alpha Aluminium, and there's no decoupler. However, it's still a performance bike that's ready to race.

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.

Trek Émonda SLR 9 eTap road bike in review

With the Émonda SLR 9 eTap, Trek send a climbing specialist into our group test. The current model has been given some aerodynamic upgrades for which the Madone aero bike served as inspiration. Is this enough to take on the four fastest race bikes of the 2021 season?

Get an overview of the grouptest here: The best race bike of 2021 – 5 high-end models on test

The Trek Émonda SLR 9 proved that it is a capable racing machine not only with a stage win at this year’s Tour de France. The Émonda has always been lightweight, so the focus for the current model was on improving aerodynamics in order to increase performance across its whole spectrum of uses. In addition to adapted tube profiles, the Bontrager Aeolus RSL 37 wheels, which were specially developed for the Émonda, and the one-piece Bontrager Aeolus RSL cockpit should also contribute to this. On our size 56 test bike the stem is 100 mm and the handlebar is 420 mm wide. The 700 x 25C Bontrager R4 320 tires mounted on the 37 mm deep, 21 mm internal width rims, measure 26 mm wide.

This bike needs speed – then the concept works. However, it can do little at half throttle. Are you looking for a race bike? Here it is!

On our test bike, Trek spec a SRAM RED eTap AXS groupset with 48/35 t chainrings and a 10–33 t cassette. Together with the Specialized S-Works Tarmac SL7, this bike has the widest gear range in the group test, offering sufficient reserves for very demanding climbs and less ambitious riders. However, the gaps between gears are somewhat larger than the BMC Teammachine SLR01 ONE with its 10–28 t cassette. With the factory-fitted dual-sided power meter, you can keep an eye on your performance at all times and keep things under control. Thanks to the powerful and easy to modulate SRAM AXS HRD brakes with 160 mm discs at the front and rear, the Émonda is extremely well equipped for the descents that usually follow demanding climbs. Here too, the rattling brake levers are a nuisance, especially on rough, poorly surfaced roads. The Trek Émonda SLR 9 eTap costs € 12,999 in the standard version. The € 800 Project One paint job on our test bike brings that to €13,799. In size 56, the bike weighs 6.86 kg.

If you win a Tour de France stage, you no longer have anything to prove – this applies to both the riders and their bikes. The Trek Émonda has already fulfilled its duty, yet it has to deign to show what it’s capable of, and that it does! Thanks to its low weight and high stiffness, it accelerates willingly in any situation. However, on the flats and undulating terrain, it doesn’t hold its speed quite as efficiently as the Specialized or BMC.

On climbs, it always offers enough reserves and happily hangs with the other bikes in the pack. However, it falls somewhat short of our expectations of a dedicated climbing bike. On the downhills, it is also in the middle of the pack over our timed section – faster times are prevented by a lack of confidence in the Bontrager R4 320 tires, which tend to lock up too easily at the rear when braking. In terms of speed, the Trek doesn’t show any particular weaknesses on any terrain. However, its problem is that it doesn’t outperform its competitors either. Thus, it takes the longest time for our calculated 150 km test route with almost 2,000 metres of ascending, covering it with an average speed of 25.7 km/h and taking 5 h 49m 56 s to complete it.

The bike’s handling is purpose-built for racing and very agile. For experienced riders, this is a real pleasure and makes for great manoeuvrability, especially in technical sections. However, for newcomers, it can seem nervous, especially when riding slowly. Comfort is also subordinated to its racing bent: vibrations are sufficiently damped but overall, the Émonda is very stiff. Those who race with it will celebrate the direct feedback from the road, all others will perceive it as too firm. However, it is noticeable that the bike’s comfort increases the harder you push it – a real race bike! In terms of safety, we have to mention the Bontrager R4 320 tires, which struggle to offer optimal grip when braking at the rear. Especially in the wet, we recommend changing the tires for something that generates more confidence and a greater sense of safety. Otherwise, there are no complaints thanks to great brakes and high precision. By the way, this very bike will be at the start of the Ötztaler Radmarathon at the end of August!

This is where you eat up the miles, setting a quick pace for a long time. Anything that is pan flat or includes short punchy climbs or slightly longer ones, albeit with limited elevation gain, falls into this category. If you want to be fast here, you need a bike that offers excellent aerodynamics and maximum efficiency – from 15 km/h on level ground, air resistance is the greatest force a cyclist needs to overcome. On the other hand, weight is comparatively insignificant, with no need to constantly change speed or fight earth’s gravity. However, the most aerodynamic package is no use if the rider ruins everything – after all, they are responsible for 75 % of the total drag on a bike. To blossom fully in this terrain, a bike needs to do well when it comes to ergonomics and comfort so that the rider can maintain a low and aerodynamic riding position for a long time. On top of aerodynamics, rolling resistance, comfort and smoothness play a key role. Thus, tire dimensions and pressure should be adjusted to suit the surface for maximum speed. A nervous bike will tire you out faster, because it requires constant work to hold your line. ↩

The steeper the hill, the more significant weight becomes. That’s because as your speed drops on ever steeper climbs, air resistance decreases too, meaning that gravity becomes an ever-larger proportion of the force acting against your progress. Stiffness in the right places, together with a sensibly chosen gear ratio, ensure maximum climbing efficiency. A good climbing bike delivers low weight and gearing that lets you maintain a smooth and comfortable cadence. However, it also takes aerodynamics into account, given that there’s usually a descent after every mountain – what good is the best time on the mountain if your whole advantage is wiped out by poor aerodynamics on the downhill? ↩

Descending a mountain quickly is possibly the most demanding task for both rider and bike. The steeper and more winding the descent, the greater the handling skills of the rider need to be and the larger the demands on the bike itself. A good downhill bike combines aerodynamics with balanced handling. It should be agile and yet offer sufficient security to master fast changes of direction and stay safely on track at high speeds. It needs to deliver the highest precision to hit your chosen line exactly and steer quickly without excessive input required. If you ride fast, you need good anchors too: powerful brakes that are easy to modulate are fundamental on every good downhill bike. To put that braking power on the ground, tires with good grip are needed and they’re just as indispensable for fast cornering. In addition to the tires, the frame itself helps generate grip through corners. If it’s stiff as a board, it can’t build up much grip before being shaken up by the smallest bumps. An appropriate amount of flex ensures optimum grip in bends, but it’s a narrow margin before the bike simply becomes spongy and imprecise. ↩

Trek Speed Concept Aerobars – keep breaking

I like to ride aerobars facing slightly upwards. The Speed concept bars allow a small degree of angle. I would like more, but this is about as far as it will go.

However, when keeping aerobars at this angle, seems to place great stress on one of the bolts.

Over time the bolt shears and breaks off.

This happened last year and I put it down to a bad angle of set up.

After getting a replacement bolt set, I took great care to place the bolt into the bracket at the right angle (not stressing it). It was very difficult to tighten this bolt as you have to hold the nut from underneath and then screw down. It’s one of those jobs, where you could do with a third pair of hands.

Unfortunately, I had same experience today, about 12 months after last aerobar failure. Again the bolt sheared away, leaving just one bolt holding everything in place.(at bottom, featured below).  Of course, the aerobars come loose and wobbly. I was 40 miles from home, but at least it wasn’t in a race.

Once might have been bad luck or poor set up. But, the second time around I tried everything to tighten up correctly. To happen a second time is a real problem. Also, I know it has happened to other riders.

Thanks for comments

Thanks for people who leave comments sharing their experience with the bolts shearing off. It shows it is a widespread problem and not just due to inadequate set up.

Also, it seems that Trek’s response is inadequate, with no-one able to get a satisfactory solution. Trek just seem to try and fob riders off.

I contacted Trek and they said:

“ What I believe could have happened is where you have adjusted the tilt of the bar, you have bottomed out the set screw on the top cradle, if this occurs, the force is put onto one bolt rather than spread between the two. please also make sure the bolts are not being over tightened, all torque settings can be found in your speed concept user manual.

I’m not sure what they mean by set screw, but a fellow rider suggested:

“Tightening the bottom bolt (closest to you when sitting) first. This should angle the bars all the way up. THEN tighten the other both (what looks like the broken one). There is also the extra smaller grub screw that you tighten LAST – this helps stop the bars moving once position is set.”

Try replacing the bolts with ordinary (but good quality) non-stainless ones. Assuming they are stainless steel bolts, they will be inherently weaker than non-stainless, hardened steel ones.

Did you ever get this problem resolved? I have a friend that has the same problem and the Trek shop has not been able to fix it. He has had it in the shop five times in five weeks

Not to my satisfaction. I never know how long they are going to last.

I had this exact issue occur last weekend. Do you have a part number for the replacement bolts and T nuts?

sorry no. Trek were not particularly helpful when I enquired. Last summer I ordered a whole replacement set of nuts and bolts, but it never arrived.

Does anybody have an update on the top cradle bolts snapping? Mine have snapped/sheared 4 times. Each time, they have been replaced with the Trek replacement bolts and torqued to spec. I do not live near a Trek dealer so having trouble getting any useful information about this. Thanks.

Hello – I recently had this same issue occur during an Ironman event. I fortunately was not hurt/did not wreck as we approached speeds of over 50mph on the downhills but it did cause me to ride aero-less for a little less than half the distance. The design is on a very high shear point and the bolt’s flat out are failing as they are what i suspect the inappropriate grade for the tensile force applied. The bike is currently at my LBS and I am waiting to hear back the manufacture – if they simply replace the assembly with the same material I will conduct the proper testing to see what replacement hardware is needed to survive in this environment.

Hello, thanks for the reply. I have just had my 6th bolt shear and am beyond frustrated. If you have Found a good solution, kindly share here. I am at the point where I no longer feel safe on this bike. Thanks!

The manufacture replaced the entire assembly kit with the same bolt and T anchors. I am doing my own testing at this point on the bike as the original assembly was performed at the Trek dealership and not myself. I have completely disassembled and reassembled the system with the new provided anchors and bolts with Trek recommended specifications and locktite. If the bolt fails again I will than look further into a different clamping system and bolt material (IMO its a matter of when not “if”).

When designing the bolt and anchor they ovalized the allen bolts to act as a pivot based on where the base bar is set and Anchor angle. The shear rate I can only assume is so low as Trek has quite the warranty on Carbon Fiber components and with components such as this I only assume they designed a bolt to fail before a mono extension carbon failure.

When speaking directly to Trek the simple answer given was it was an isolated case and unsure of the exact failure. This is a very dangerous situation IMO and I am not 100% certain that a off the shelf bolt can appropriately work to solve the issue.

The best advice I can give to any hesitant or concerned athlete/owner at this time is to simply sell the bike and look for an alternative as at this point in time the issue does not seem to be resolved from the manufacture (Owner of 3 – 700 series carbon bikes)

ALSO – The set pressure screw does not support the rear bolt, only the front bolt

My bolts sheered off last Saturday while I was riding at 26mph. Luckily I only suffered a crushed helmet and fractured scapula. This sounds like an on-going problem for sure.

And again 11/07/2020 at mile 60 of Ironman Florida. Had to ride back to transition on my base bar into a headwind upright. Cost me at least an extra hour.

I’m pissed… Probably will see all three of my treks.

Omg that sucks! I had to ride my “backup bike” (QR) in Ironman Florida because my Speed Concept has been in the shop over a month due to the broken bolt issue, faulty Di2 wiring n a shitty Project One paint job on a bike I’ve had barely over a year. Trek said they wouldn’t cover any of it! Ugh!

My rear bolt sheared off on a downhill, 30 mph at Ironman Hawaii 2017. I keep my bars level to 1 degree upward tilt which probably increases the stress on the rear bolt, especially downhill with more weight on the front end. I hit a small transverse seam in the road and bang. The aerobar pitched forward and swivelled side to side. Nearlly crashed. Bike in the shop now.

Larry – sorry to hear this. I also suffered the same failure during Kona 17 which resulted in a DNF and a broken hand. Glad to hear you did not crash..!

I had the same problem last Saturday….Has anyone found a solution for this issue?

I may have found a solution, but like all of you have conveyed only time will tell.Hang in there with me as i describe what i have done… I have taken off the screw closest to you (the rider), and added a spacer so that the handle bars lay flat, and eliminate the angle that is the root of this design flaw.

So far it has accomplished two things. First, it allows us to be in a more aero position, and secondly it eliminates the stress put on the screw due to the incorrect angle.

Process: It involves removing the undercover of the handle bars (three screws), which allows for manipulation of the top side and addition of the spacer (which eliminates the challenge)

Again only time will tell if this will really work, but as my buddy(an engineer) and I evaluated it, this may be the ticket. Kind of a bummer that we have to collaborate like this given the bike we all own, but i don’t like reading about fellow triathletes getting injured, and possibly hurt much worse.

Wishing all of you a safe ride. Hope this helps.

Hi EM, Did this solution work? If yes, how did you create the spacer? Cheers,Quentin

I had the same failure. It was in a race but fortunately I stayed upright. I have the bars angled upwards but I don’t really understand why this overstresses that bolt or what I can do about it.

I’m about to switch over to the alternative aerobar setup (at great expense) which allows you to use generic poles and, therefore get far more upward adjustment. Will this fix the problem?

Hey to all of you; I‘ve had the same problem with my new Trek speedconcept during an ironman in Vichy (France) 8/2018. The aerobar untightens by itselfs after 25 Miles und i couldn‘t use the aeroposition during the race!!! I‘ll bring it to my bikedealer next week.

I don’t believe there’s a fix for this common issue of the bolts shearing. Mine broke at 32 mph going downhill and I was amazed I didn’t crash. As I wheeled my broken bike into the Trek store a woman was bringing hers in with the same broken bolts!! Mine had been serviced by experienced techs at a Trek store and was only one year old.

Do a Google search and you’ll find numerous examples. Not sure what to do about this with an expensive bike I like otherwise (except for the rear brake sticking).

I’m sure other companies have had a product recall for less.

https://forum.slowtwitch.com/forum/Slowtwitch_Forums_C1/Triathlon_Forum_F1/Speed_Concept_Aerobar_failures_P6601686-2/

This is very concerning. Had the same issue with the aerobar bolts becoming loose. Just recently crashed when the aerobar bolts sheered and during IM Chat had to stop twice to correct loose bolts. At LBS now. I will update post when I get bike back. I’m very concerned and frankly not confident riding the bike.

How about replacing the bolts a few times every season ?

How about Trek providing a solution? What if this was a car and the steering wheel randomly would fall off? I’ve have 3 snap in three years. And my bar is level, not in the praying position. I don’t feel like spending $8k on a new bike. Huge design flaw.

Companies do product recall for a lot less

It’s interesting to find that during 2019 Trek changed the design of the Mono bar (and the alternative Mono Plug-in) to accommodate 6mm bolts and T-nuts in place of the original 5mm bolts and T-nuts. Trek also changed the design of the Mono slider to suit the larger bolts. The replacements are referred to as ‘6mm hardware’ versions. Mono bar straight W582442 Mono bar long W582443 Mono bar short W582444 Mono bar S bend W582445 Mono Plugin – W582446 6mm bolts and T-nuts – 596164 Mono Slider – W582447 Officially, the only way to upgrade is to replace all three parts with the new parts although it might be possible to widen the slot in the original 5mm mono bar/mono plug-in and just replace the bolts, T nuts and slider?

Perhaps unsurprising that Trek appear to have never accepted that the original 5mm hardware was prone to break.

Apparently Trek revised the design after collecting the feedbacks on the previous one. If I were to just replace the whole set of basebar + extension bar with a different brand, do you have any suggestion of brands & models that can retrofit into the Speed Concept?

I have 2021 purchased SC and just recently got the issue in race. Bolt was not broken but got loose and could not ride on aerobars. Though I had messed it up myself but maybe not…

Anyone ever get a good answer to this? My rear bolt sheared during Ironman Waco this weekend going down a hill. Amazing I didn’t crash.

I have a 2020 speed concept. Had this issue last year (2022) and had it replaced to specs at a bike shop with locktight. It happened again, less than a year later in a race. All I’ve heard so far, is “use locktight” and it won’t happen again. I’m beyond frustrated.

I wish I had found this post and would have decided not to purchase this model/year of the speed concept. the bolts on mine snapped as well, and thankfully I was slow enough to land my forearms on the handlebars and control to avoid a fall. Now I will be looking for a model with 2 supports instead of the mono. too risky not knowing when the bolts can snap again

This is a thread I wish I found awhile ago. I came up with a simple solution. I placed a third bolt with washers in most front part of the bars. I don’t knownhow to explain this with out pictures but here goes. Imagine having a third bolt that when the bars are that the most prayer like angle and without the standard mono bolts tightened, the extra bolt stops the bars from leveling out. I consider this to be a support bolt. Then I tightened the standard bolts. This way there are 3 bolts that share the load and not just 2…happy to explain further if anyone needs more info. Hopefully this might help someone who still has this bike and suffers this issue.
