It was only a matter of time. Disc brakes on road bikes are a common sight as more manufacturers add disc versions of their bikes to their lineups. Disc brakes went through a controversial period, particularly for road racers. And in early 2018 the UCI finally approved disc brakes for use in UCI sanctioned events.
But triathlon has never been subject to the same sanctions and rules of the UCI. This includes frame design and scope. Disc brakes could have been in triathlon much earlier. But public opinion and skepticism about their benefits kept manufacturers from implementing the technology on triathlon bikes.
But that’s all changed.. Felt launched its 2019 Felt IA triathlon bike with disc brakes.
