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.
microSHIFT's robust 2x8 drivetrain can handle everything you’re throwing down while confident braking from Radius CX7 mechanical disc brakes seals the deal of the century.
