Hot Disc Brake Concerns Raised in the Pro Peloton
Pro cyclist posts video of how hot disc brakes can get under extreme braking
A dutch professional rider Reinier Honig from posted a video saying “How about this aspect of disc brakes? #hot #ridersafety #nostitchesneeded”
The introduction of disc brakes into the professional peloton has been a high contraversal issue. The UCI originally trialled disc brakes in professional road cycling at the end of the 2015 season, and allowed widespread use in 2016, but they were banned after Francisco Ventoso suffered a deep gash to his leg at Paris-Roubaix.
Ventoso said that Nikolas Maes also suffered a similar injury during the same race. Ventoso’s concerns prompted the UCI to suspend the use of disc brakes in road races.
In that time both the French and Spanish federations stated that disc brakes were not allowed to be used in amateur events. The French Cycling Federation (FFC) banned the use of disc brakes in all of its events, including L'Etape du Tour and the Marmotte Gran Fondo - due to safety reasons.
However in October last year, the sport’s governing body announced that the trial of disc brakes in the peloton would resume and subsequently the FFC and RFEC federations removed the ban allowing amatuer rides to use disc brakes in Sportives and Gran Fondos.
June’s restart of the disc brake trial included one key modification to existing equipment in order to address at least one of those issues — rounded edges on rotors, so as to minimize the chance of laceration.
UCI Equipment Commission did acknowledge athletes’ lingering concerns of sharp edges on disc rotors, the possibility of contact burns from rotors that have become hot after braking on long descents, and the effects of a ‘two-tiered peloton’ where some riders are on rim brakes and others on discs.
It seems that the second concern regarding contact burns from hot discs hasn't yet been addressed.
Other professionals including Wout Poels of Team Sky who tagged the UCI in his retweet and Lotto-Soudal’s Louis Vervaeke who said: “nice, so now we can fry our eggs on training.”
