Specialized Rockhopper Sport 29 Features
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 Radius mechanical disc brakes, shifting from microSHIFT 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.
At a Glance
- 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 Radius's BR-CX7 mechanical disc brakes.
- 2x microSHIFT 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.
