Rockhopper

2021 Rockhopper

Better performance. Better value. Better Rockhopper. By tapping the fit and handling advantages of pairing each rider with their ideal wheel size and suspension that works its hardest for everyone thanks to our size-specific Rx Tune, we’ve baked in added performance to the all-new Rockhopper without dialing up the price.

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.
