Following the accident involving Movistar rider Fran Ventoso at Paris-Roubaix, the UCI will suspend the use of disc brakes in professional road racing amid safety fears

The UCI has officially suspended testing of disc brakes due to the risk of injuries suffered by riders in races.

In a press release on Thursday, the sport’s governing body suspended testing with immediate effect, following a request by the AIGCP – which represents all professional cycling teams – which was supported by the Cyclistes Professionnels Associés (CPA).

CPA calls for a suspension of disc brake use in pro racing

“The UCI will now continue its extensive consultations on this subject by way of its Equipment Commission, which is made up of representatives of teams, riders, mechanics, fans, commissaires and the bicycle industry – via the World Federation of the Sporting Goods Industry (WFSGI) –, all the while reaffirming that rider security has always been and will always remain its absolute priority,” the UCI said in its press release.


Watch: What do the pros really think of disc brakes?


During last Sunday’s Paris-Roubaix, Movistar rider Fran Ventoso was reported to have suffered a serious injury which he said was caused by a disc brake on a fellow rider’s bike, a claim that was questioned by Lampre-Merida, one of two teams using disc brakes at Paris-Roubaix.

The 33-year-old’s injuries to his lower left leg required surgery on Monday. Following on from this incident Ventoso wrote an open letter in which he said “disc brakes should never have arrived in the peloton.”


More on this story


Speaking to Cycling Weekly on Wednesday, the CPA told us it had contacted the UCI over suspending the use of disc brakes.

“We have written a letter, with the Equipment Commission, to the UCI to formally request that disc brake tests should be suspended,” the CPA said.

    As a consumer I want the latest fad but I like to be mechanically efficient and beautiful. The argument is about the front hub and its disc brake. Why not incorporate the disc within the hub and hide its cutting edge? Bring back the drumbrake? We consumer cyclists are looking for the elegant solution, invent it and even the UCI will step into line. We are retreating from using the wheel rim as a braking surface as we have retreated from using mechanical pull brakes working on the underside of the rim. We have gone through side pull, centre pull, cantilever and v- brakes. Now we want braking on the hub.

  • Tim Williams

    Yes some day. They want them. Would like to try them. But they are not ready yet. All are comments from the link provided.

    Also included were concerns about how it would be done and the safety of said brakes.

    Do you not believe that a pro would understand that discs could have a benefit but would need to be changed so that they are safer before they are introduced. Also note that they understand that if one person has them then for safety sake all should be riding them.

    I still see no one championing the cause to have them on their bike. I read that some are interested and would like to try them but no demanding that they have them now and as is.

    In the near future sure but there are still issues that need to be worked out and their safety is the first and most important concern. Even in your link there are safety concerns presented and getting cut is right there. Predicted before it happened.

    Thank you for showing me that there are a few pros who would like to use them. However, the majoity have been vocal against them being used in pro races..

  • Tim Williams

    Google search is great. You’ll find video of pro riders stating that they were not given a choice but told to ride disc equipped bikes. Yep it is there. Hmmm. How about taking your own advice genius!

  • RobTM

    You ignore completely the issue of carbon rim heat dissipation. Secondly stopping to clean a bike whilst out in the rain on a ride is NOT practical, I’ve had Alu rims go due to grit very quickly. Thirdly it’s an answer to the question posed about how consumers lose.. no-one is saying you have to buy a new bike. However, I do NOTICE that even out here in dry Mallorca very many riders out training have opted for dics already

  • Tim Williams

    Not if you clean and maintain them. Yes they stop better however, how much stopping power do you need to stop a 25mm road tire. I can lock up the tires on a wet and rainy day riding on a bike circa 1993. With the original wheels brakes and pads. Come on now just because they have more power does not mean they are needed. Let the consumer choose. Quit with the propaganda. On my gravel bike, sure hydrolic discs, on a touring, sporting, or tandem yes to discs, but on my road bike I will pass so quit trying to push on me and other roadies what we do not want.

  • Tim Williams

    The UCI has nothing to do with what is offered by manufacturers. Manufacturers Taylor what they put out based on possible sales not on UCI guidelines. Road racers for the most part do not want them. They increase the time it takes to do a wheel change, look horrible, are not aerodynamic and increase the cost of racing by making riders who switch have to spend an enormous amount of money. I already have 4 wheelsets and could not afford to replace them all with the purchase of a new bike with discs. What is available is actually quite a selection of both disc and non disc bikes. A road bike with Shimano 105 will cost about $1000 and with Shimano Ultegra would begin about $1800 and from there the price goes up. If you are looking for a bike for less then there are several 8, 9, and 10 speed options. Quality depends on what you pay and that is across the board. Still not seeing how the UCI has anything to do with the offerings coming from the manufacturers. Next is the decisions of the shops as to what to offer which is different from shop to shop and city to city. Still not seeing the UCI influence. Roadies are very set in their ways and have specific parameters for their bikes. This is more of an influence than the UCI. If I can make one sale for $5000 or a $700 bike which one makes more sense for a time strapped shop owner, with both requiring me to spend 2 hours with the customer, which would you choose?

  • Retrovirus

    The only losers here are the Peleton. Disc brakes are the reality in mountain bikes and are quickly becoming the reality in commuter and now road bikes. At this point it’s hard to imagine the manufacturers going back to rim brakes for their high end bikes. There are simply too many high end carbon and aluminum bikes out there that use rim brakes. To me discs are the only reason to upgrade. I feel that people who judge disc brakes should remember that you can make a very cheap as well as a very powerful disc brake. Just because a manufacturer choses to equip a bike with disc doesn’t mean that company has to use good ones. Likewise with the hydraulic versus mechanical brake the a BB7 mechanical brake is far better than a cheap hydraulic brake system , the technology is only better if you build it with the right components.

    However one area where disc brakes have an absolute advantage will be safety on long descents, no more rim meltdowns will occur with disc brakes. Disc brakes are here to stay in road and mountain biking and the Peleton forgoes a potentially huge advantage when faced with sustained descents and inclement whether.

  • Doxxes

    So a spiky metal chainring is fine, but a smooth disc brake isn’t?
    One rider claims to be injured by a disc and discs are banned, but multiple *televised* crashes with vehicles including fatalities and vehicles are still welcome?
    Sounds like they just wanted to ban discs. Which sucks for consumers as we have to now rely on inferior braking technology, just because the UCI don’t like change.

  • Michael

    Well yeah specialized are pricey. Genesis datum seems better priced then the diverge carbon comp.

    Finishing kit perhaps not as good though.

  • Ziggy Tomcich

    I had a budget for buying a bike. Like most bicycle geeks, I broke it! I wanted an endurance road bike that I can race in Triathlons with. The selling point for me for the Diverge was that I can do anything with it. Attaching panniers to a carbon frame is huge for me, because wearing a backpack on long ride sucks. Most of my long rides I’m going someplace to do something. Carbon frame + disc brakes + cargo + race worthy = Diverge. Trek looked promising, but the stack and reach numbers are very close to what I’ve been fitted for and I was told I couldn’t put cargo on a Trek. Plus the closest bike shop that I know and trust gave me a good deal on the Diverge.

  • Ziggy Tomcich

    Yes, but my argument is that if the UCI didn’t exist, we’d probably have disc brakes on all bicycles by now because they offer superior performance and reliability. People shouldn’t have to spend $2000+ just to get a bicycle with working brakes. The manufacturing costs aren’t that different. The UCI should not have that much control over what consumers can buy.

  • UCI should not have suspended them immediately after just one accident between team riders. They should remain as an option for each rider to choose freely. Like Cancellara said it should be technical and personal decision. But still, i do not like the fact that sponsors and manufacturers are pushing teams to use disc brakes, even when their riders won’t use them.

  • RobTM

    Yes, I quite sympathise.. if a car overtakes me on lead into a narrow windy descent, I’ve learnt to back off; because every now and again a car brakes suddenly, surprised when oncoming traffic and/or climbing cyclists are there and they (incorrectly) fear the lanes are not wide enough to pass safely. If you follow close looking to pass, you run risk of going into the back of them or skidding off when they do this

  • RobTM

    Consumers lose because Carbon wheel rims, have to have expensive additives added to disipate the potential heat generated on a long alpine descent. Seperating braking to a specialist rotor, allows the wheel to remove one compromise. Aluminium rims suck because the metal is too soft, as soon as you get any grit on them from spray, or rain riding, you risk rapid wear and or dangerous sudden rim failure due to somethign caught in the brake block. Discs do have their downsides, mine have a fiddly cable adjustment for instance, pads can also wear quickly or become slippy due to contaminants; so for summer riding I went with the standard rim-brakes to be able to swap wheels

  • Aaron Paterson

    “No one cared who I was until I put on the mask” – Bane lol

  • Colin Faulkner

    Perhaps we should have a person walking in front of the peloton waving a red flag. All forms of racing is dangerous disc brakes or not. Why stifle progress and improvements because of one incident? This is typical of the knee-jerk reactions that happen everywhere these days. For example one kid gets hit by a car near a school and the rest of humanity has to drive 40kph near schools. Why not be responsible for your own actions? I don’t think anyone in the peloton has been forced into being there. If they think discs are too dangerous, go and do something else! There are thousands waiting in the wings to take their places.

  • BuffyzDead

    What’s happening with Roompot is the entire organization is working their chamois’ off, switching all their bikes and car racks, to support rim brakes. They need too be race ready by this Sunday

  • David Curran

    I saw a copy of his open letter and images on Cycling Tips. Might be able to find it there.

    Also in reply to Norfolk, that is not the story that happened, and not even his own story. It is full of vague accusations, from someone who has a hatred of something and is afraid to change, like yourself. Read his account, and tell me 100% that there is no other possible way, and that without doubt that it was a disc rotor, and I’ll retract my statement and agree with you.

  • Tim Williams

    The 105 equipped Diverge Comp ($2700) is overpriced. A Ridley X-Trail CR1 with Ultegra and hydrolic discs is only $2800. It is all about looking at all that is out there.

  • Tim Williams

    Also, there are not many hydrolic options due to the lack of hydrolic brifters. SRAM leads the way but is pricier than Shimano who only has 2 hydrolic mechanical options and both are pricey. Mechanical discs work decent but not that much better than Shimano’s direct mount rim calipers. I have a bike with 1993 Shimano 600 brakes on it and have never been in need of more braking power (even in the rain and snow).

  • Tim Williams

    If you don’t mind me asking what was your budget? The lack of disc brakes surprises me as a majority of manufacturers have gone disc on their endurance road bike line. It could be more the bike shops not ordering the disc options for fear of not selling them.

  • Ziggy Tomcich

    I just bought a Specialized Diverge carbon and I’m super happy with it. But the shopping process for a bike really sucked because most road bikes I looked at didn’t have adequate brakes. For riders in the Peleton they probably don’t need disc brakes. But as a consumer, because of the UCI I had far fewer choices and ended up spend way more money then I should have for a because the only road bikes with adequate brakes were the premium models. This sucks for consumers. Brakes that work reliably in all conditions shouldn’t be a premium feature. I live in San Francisco with really steep hills with lots of questionable fluids on them late at night! I have more stopping power driving a car then I do riding a bicycle with caliper brakes going down the same streets at the same speeds.

  • Sean

    Where can you see the injury ? I can’t find it

  • Simon Barnes

    Just my feedback on my data on my bike.

  • Tim Williams

    The riders Union and team association requested they be removed from the peleton. When the riders request them back, then they will return. If they do not request then what is all the fuss. It is ironic that non racers seem to believe they are the voice of the racers. I have yet to hear a single pro rider say they want discs and only disc brakes.

  • Tim Williams

    How are consumers losing. Every manufacturer produces bikes with disc brakes. If they are banned from road racing how does that stop a consumer from buying a bike with them. So should we put disc brakes on track bikes too? Then more people could get them!!!! Sarcasm abounds. Discs are good and have their place (Mountain, cyclocross, hybrids, and even gravel road bikes) just not in a peleton.

  • Declan Bowler

    Roompot are only using disc brake bikes? Whats happening with them then?

  • WhiteCatzs

    That’s outrageous ! Any moto driver hitting a cyclists should be banned for the entire season and fined a huge amount of money, that shouldn’t be covered by the driver’s insurance.

  • mikeq

    Yeah I thought it was subjective too, but Mr Norfolk stipulates it’s “Fact” even includes an exclamation mark to reinforce it. 😉

  • Sean

    So are you saying that you have conducted a survey, and you have proof that using disc brakes have cost you watts? How many watts have you lost? Is it enough for you to lose seconds of precious time in a grand tour?

  • Sean

    How things look are subjective. My favourite pro kit is AG2R.

  • Sean

    I know, they finally banned somewthing because a rider alledgedly got a cut from a disc rotor. Too bad nothing seems to be done about a rider being killed by a motorbike.

  • Claudio Pavan

    I really don’t think its important what any of us outside of the pro peloton think! If the pro’s dont want them then they don’t want them. It really doesn’t make a difference to your group ride on sunday where you all have shiny new disks.

  • harry

    Against slugs like yourself, I fly.

  • Leodis75

    Should have guest, I bet you wear Sky kit as well FPKW. No doubt blowing out of your rear on box lump each week. I’d bury you and still have time to pop around to your mothers.

  • Norfolk_n_Chance

    Now we both know you don’t fly past people. Thrush, Ducks and Hmmm other dickie birds yes, but not humans. Get your facts right!

  • Norfolk_n_Chance

    Can’t stand Brad!

    Team Froomey all the way.

  • Norfolk_n_Chance

    Alright Dazza!

    Actually did a bit of rugby at school, but was completely bored playing it so took up the Sport of the Gods (road racing) 15 years ago.

    If you’re a bit scared (Eek!) or racing and don’t want to test yourself on the weekends against pros, semi-pros and blokes who hold down full time jobs (but who are actually pretty good)… then you’re a fat old slow disc brake (dangerous as they slice you up!)(please see my original comment about them being guff) riding bumbag (sportive riding (i.e. not racing)) muppet.

  • harry

    No, I question why such fools are so arrogant in their lycra as I fly past them.

  • Darren

    Oh and im not middle aged im 29 just hate big headed people who think they own a sport….now go play with yourself over a picture of Brad.

  • RW

    Too bad SRAM, Shimano and the like think the only way to sell discs is to have pros riding them. I think they make a lot of sense for a lot of riders and I’m glad they’re available to wet weather commuters, tandem riders and anybody else who need or just want them. If they’re not appropriate in road racing, equipment suppliers shouldn’t be cramming them down the riders throats.

  • Darren

    This is why normal cyclists hate these so called think i am bradley wiggins type who would never have made it as a professional cyclists but are still childlike thinking they are. Now grow up you will never be a professional athlete cycling is for everyone, i bet you were the kid at school who use to cry when tackled in rugby or never done a contact sport in your life

  • Norfolk_n_Chance

    Do you get upset when a group of racing cyclists whizz by and you wave at them but they don’t wave back?

    That’s because racing cyclists HATE all other disciplines apart from the one they actually do and…. fat middle aged sportive disc brake riding cyclists are ignored by them with cherries on top!

  • harry

    Twonk, go race up your own chuff

  • harry

    What a gnob.

  • Norfolk_n_Chance

    Apart from when the bloke in front crashes and you slice him up with you front brake. Eeeugh!

  • Norfolk_n_Chance

    Glad you agree

  • Norfolk_n_Chance

    Why have UCI suspended disc brakes? Cos they cut people up… my other comment about them looking rubbish, is because they look complete guff. Fact!

  • Norfolk_n_Chance

    Are you middle aged (guessing you are as your [AddNameHere]75)?
    Do you ride Bumbags (aka Sportvies)?
    Do you own a disc brake bike?

    If you answered yes to any then your a hobby cyclist and have no clue.

  • Kim Moon

    Kind of like the NRA?

  • Leodis75

    “Fat middle aged sportive riders (i.e. not racers!)” haha you sound such a tool

  • mikeq

    Look rubbish? Have you seen AG2R and Lampre team kits, well, if we’re banning things that look rubbish.

  • mikeq

    So it cauterizes the wound. Sounds like a benefit

  • harry

    Look rubbish you say? Blimey, best ban them sharpish!

  • Simon Barnes

    I bought the focus izalco max disc on the back of the hype and its the most disappointing waste of money and more importantly watts ever. I suspect the latter is the real reason none of the real contenders have ridden disc brakes during the classics…..

  • David Curran

    Have you seen the injuries.
    There is no plausible way that the cut to his leg was caused by a brake disc.
    He even says he was not involved in the pileup, and merely put his leg down. Speaking from years of experience of bikes with discs, you CAN NOT cut your left leg on a disc rotor if the bike infront of you is facing forward.

  • llos25

    It is also the heat .

  • Norfolk_n_Chance

    The topic is about disc brakes (not motorbikes or spokes). And yes, they should be banned from UCI and BCF events as they look rubbish and cut racers up.

    Fat middle aged sportive riders (i.e. not racers!) don’t know the dangers associated with disc brakes so let’s leave it to them to buy, ride and injure
    themselves with.

  • Chris Mann

    What??? Ridiculous! And if in fact disc brakes caused the injury, manufactures could always radius the outer edges of the rotor round.

  • kees kroket

    so we can expect a stop on the use of motors? Really strange decision from the UCI. One guy tells them that his injury is caused by disc (no actual evidence) and there is actual evidence that a motor caused the death of a rider, but no suspension of motor’s

  • Ziggy Tomcich

    If the UCI didn’t exist, disc brakes would’ve become the standard on every bicycle a long time ago. Consumes loose. It sucks that the UCI had so much influence over most of the bicycles we buy yet most of us will never race with.

  • velocite

    You don’t know that he was injured by the disc. His story is impossible to reconstruct. How do you injure the outside of your left leg on a disc on the bike in front of you? I suspect Ventoso’s injury was caused by the buckle on the leading rider’s shoe. The UCI’s reaction is premature and reflects badly upon them.

  • Ciaran Carroll

    In pro racing when there is a mass pile up there are people and bikes EVERYWHERE. This incident may not have been through a mass pile up but Fran Ventoso was injured by the disc. Mass pileups tend to happen during fast racing on the big ring. Amputated fingers? I’ve never heard of people losing a finger because of aero spokes in the pro peloton. I had a look around and the only case I could find happened on the velodrome with a composite 3/5 spoke wheel not bladed spokes. If spokes are such a danger how come we don’t hear of more people being injured by them? I’m not anti-disc I just think more time should be spent on minimising the chance of people getting cut by disc brakes by adding fairing before discs are re-introduced.

  • Rob King

    A rider is killed by a moto and it’s business as usual but get a dubious cut from a disc brake and it’s the end of times!

  • Cory Ross

    If the guy did not fall down and the cut was on his left leg that makes it very difficult for a disc(mounted on the left side of the bike) from another persons bike to cut him. If they are going to ban disc brakes because of the potential injury they might want to take a look at chainrings, and aero spokes. They are just as dangerous, aero spokes have amputated fingers in the peleton.

  • WhiteCatzs

    Finally. Too bad it always takes an accident for logical decisions to be made.
