Specialized Rockhopper 27.5 Inch Hardtail Mountain Bike in Black

Shimano and MicroSHIFT team up for drivetrain duties with a robust 2x8 drivetrain that can handle everything you’re throw down while confident braking from Radius CX7 mechanical disc brakes seals the deal of the century.
Key Features:
- A heart of gold, presented in 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, Specialized have 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.
- With Rx Tune on Rockhopper, the SR Suntour XCE brings size-specific travel and spring rates to the show in a performance that’s sure to impress while also ensuring consistent geometry, handling and suspension performance, regardless of frame size.
- Radius CX-7 disc brakes offer confident, consistent braking in any trail condition.
- A durable Formula freehub and SunRace 8-speed cassette keep you rolling smoothly without putting up a fuss.
