Overview
About this bike
GT's Avalanche Comp is ready, willing, and able on the dirt. Boasting GT's light aluminum frame and a super-smooth 100mm-travel suspension fork from Suntour, this bike is a nimble machine that loves trails, scenic singletrack, and cruising on the bike path. Plus, it sports the awesome speed control of Tektro disc brakes, a quick-shifting 27-speed Shimano drivetrain, and easy-rolling, 27.5-inch aluminum wheels with grippy Continental tires.
