The Cyclistes Professionnels Associés (CPA) and Equipment Commission have called upon the UCI to suspend testing of disc brakes following the Ventoso injury at Paris-Roubaix

Following the incident at Paris-Roubaix in which Movistar’s Fran Ventoso suffered a serious injury to his left leg, reportedly from a disc brake, the Cyclistes Professionnels Associés (CPA) or Association of Professional Cyclists has formally called for the UCI to suspend the testing of disc brakes.

Since the time of writing, a UCI spokesperson has confirmed there will be a suspension on the use of disc brakes.

Cycling Weekly spoke to the CPA, who said: “we sent several letters to race organisers and the UCI and organisers before Paris-Roubaix, not to undergo disc brake tests, because we knew that many riders didn’t agree about the use of discs.”

The CPA also explained, that in these letters “we underlined all of the risks of using disc brakes.”

Despite the warnings from the CPA and concerns from pro riders “the UCI didn’t want to go back” on its decision to test the brakes. Following the the fallout and reaction from the horrific Ventoso injury, CW understands that the CPA has been in contact with both the Equipment Commission and the UCI.

“Today we had a big discussion with the Equipment Commission and we all agreed that testing of disc brakes should be suspended,” the CPA continued.

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


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


The CPA was firm to stress that it was not against disc brakes replacing standard callipers long-term, but that in the current form, there were safety issues.

The CPA said it also believes the UCI will suspend the use of disc brakes.

“Following this [Ventoso incident] we think the UCI will suspend the use of disc brakes. It doesn’t mean they will say no to disc brakes in the future, but just for now. We don’t want to stop the progress of disc brakes, but we don’t want to risk rider safety.”

    Cross country mountain bikers don’t race round in 200+ compact racing pelotons.

    .. I think the difference is that in mountain biking you don’t have a peleton of 100+ riders racing so close at such high speed…. The chance of landing on someone else’s disc brake is far higher in road racing. There have been quite nasty injuries from chain rings in the pro peleton and this just adds another risk.. A mountain biker is not that likely to land on his own disc brake in a crash and they also wear more protection in competition.

    Disc brakes have been used on mountain bikes for many years now and work 10 times better than rim based brakes. I’m not sure what could have happened to make them stop using them. They work much better with very little work at the lever like rim brakes. Maybe they aren’t used to the efficiency??

    I’m a disc proponent but it seems reasonnable to me to wait for manufacturers to present solutions / guards before proceeding with more testing. Rider’s safety should still be a priority after all.

    perhaps discs are better for the consumer not the racer – I certainly like the sound of improved wet braking and improved wheel lifespan. I know that the pros are limited by tyres more than brakes when it comes to stopping power, but it’s pretty hard to lock the wheels with sora, so the disks would be an improvement. but spinning hot discs are perhaps a little risky in the madness of the peloton, and any advantage regarding wheel life would be pretty useless to a pro who gets new kit every year.

    Oh dear, this incident sounded very odd from the start and as pointed out on another post that he injured his left leg and the discs are mounted on the left side, he also stated he didn’t crash and so I wonder how he just “touched the bike” and this happened. I think its an excuse to stop the progress of discs and looking at the comments from Ventoso its more about compatibility than rider safety.
