Speaking for the US bike brand Cannondale, Murray Washburn told Business Insider in no uncertain terms,

"Disc brakes are the future — period."

Specialized founder and CEO Mike Sinyard has said that, 

"In the future we won't look at road bikes that don't have disc brakes. They all will."

“Disc brakes I think are the future of the sport and we’re really fortunate to be on them this year...,” Craddock said. “A course like today, the descents are pretty sketchy with turns and fast descents. I’m...fortunate enough to be running discs today.”
