Rockhopper Comp 2x
2021 Rockhopper Comp 2x
Strut your stuff high and low with the two-stepping Shimano 2x9 drivetrain on the Rockhopper Comp 2x. The size-specific Premium A1 Aluminum frame makes for the perfect dance partner with geometry that lets you attack twists and turns with sharp, responsive handling and tackle descents with confidence-inspiring stability.
An SR SunTour XCM fork gets our RxTune treatment and hydraulic disc brakes keep up with whatever rhythm you throw at them, while a killer wheelset with Shimano hubs means you’ve got plenty of options when it comes to lacing up your dancing shoes.
