Rockhopper Comp 29

2021 Rockhopper Comp 29

A summer blockbuster with an eye for adventure, the Rockhopper Comp lives for high action and fast-paced plot twists and features an all-new, Premium A1 Aluminum frame making its singletrack debut.

Roll the credits to discover an SR SunTour XCM fork with a custom two-way damping circuit, Stout wheelset, Shimano MT-200 hydraulic stoppers and MicroSHIFT’s wide-range 1x9 drivetrain and you have backup provided by a supporting cast that’s all thriller and no filler, but will never leave you hanging.
