The Overdrive Comp is a classic hardtail mountain bike in the tradition of cross-country trail bikes, made for riders who relish all-around speed. Its aluminum frame features butted and formed tubes in a neutral geometry, making it lightweight and responsive on trail. This year we’ve outfitted the Overdrives with 27.5” wheels, making them easier to control in tighter spots without sacrificing too much traction and speed. They’re still the fastest mountain bikes we sell, able to rocket through rolling terrain and fly up climbs. With Shimano hydraulic disc brakes (180/160mm rotors), 2×10 drivetrain, and a smooth Rockshox fork, the Overdrive Comp has a component group that matches its performance.
