A mountain bike that has all the features for outstanding riding fun: modern geometry, Ground Control tires, hydraulic disc brakes, internally routed cables. And last but not least, we have installed a drivetrain with a wider gear range so that young riders can climb higher and enjoy longer descents with the Riprock 20. Kids can only ride confidently when they sit well on their bike. Therefore, child-friendly components are a priority with the Riprock.
