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.
- A heart of gold, presented in our lightweight yet durable Premium A1 Aluminum, the Rockhopper features butted aluminum tubes in order to keep weight low and strength high, all while providing increased standover clearance, slick internal cable routing and dropper-post compatibility. With the goal of making sure that the Rockhopper offers both the best fit and best performance for every person, no matter their measure, we’ve paired each Rockhopper frame size with the optimal wheel size. The result is a Rockhopper to fit every rider and the assurance that every Rockhopper is rolling on the best-handling wheel for its frame size.
- Reign in speed and dial up your confidence with powerful braking from Tektro's M275 hydraulic disc brakes.
- 2x Shimano Altus shifting handles drivetrain duties while you focus on the ride.
- A durable Formula freehub and SunRace 9-speed cassette keep you rolling smoothly and promise countless miles of fuss-free performance.
