Rockhopper Sport
2021 Rockhopper Sport
All barn-burner and no benchwarmer, the Rockhopper Sport throws out the playbook when it comes to putting performance points on the board while playing some serious defense on behalf of your wallet.
Game-ready with Tektro hydraulic disc brakes, Altus shifting from Shimano and an SR SunTour XCM fork that’s built to hustle, the Rockhopper Sport can tack up the win on any given Sunday—and the rest of the week too for that matter.
