The UCI confirmed today that it would continue to "suspend the trial of disc brakes in road races" at the request of the Professional Teams' Association (AIGCP), and are not planning to resume allowing disc brake use in the peloton until the teams agree.

The UCI approved the widespread use of disc brakes this season after a short trial in 2015, and some teams such as Roompot-Oranje Peloton, were quick to adopt and convert their team's entire fleet to disc brake frames and wheels.
Riders' fears of the dangers of a peloton with mixed braking technology appeared to come true during a crash in Paris-Roubaix involving Francisco Ventoso (Movistar), where the Spaniard sustained a deep gash to his leg, which was the result, he says, of a disc brake rotor. The incident led the UCI to suspend the use of the brakes over safety concerns.
Roompot-Oranje Peloton had to quickly refit all of its riders with rim brake frames before the Amstel Gold Race.
"We decided to suspend the trial of disc brakes in road races following a request to do so made by the Association Internationale des Groupes Cyclistes Professionnels (AIGCP) – which represents all professional cycling teams," the UCI confirmed to our sister site Cyclingnews.
"We are continuing to evaluate the situation and the test will not restart unless we and those representative groups believe it should."
Changes to UCI's 3:1 tubing rule
The UCI is also poised to make some changes to the regulations for frame construction for the 2017 season — possibly doing away with the 3:1 ratio rule tubing, which limited how ovalised tubing could be made, therefore limiting how aerodynamic frames could become. Tubing was not allowed to be more than three times longer than it is wide.
"The UCI Management Committee recently approved the removal of the specific clause in its Regulations relating to profiles in frame construction entering into force in January 2017," the UCI stated.
