Rolling on big 29-inch wheels, Diamondback's Overdrive Comp sails over roots and rocks that once stood in your way. This sweet 29er features a light, nimble aluminum frame with a tapered head tube that soars up the climbs and a RockShox 100mm-travel XC 30 fork that smooths the terrain for superior control. The big Diamondback wheels help in those regards, too. You'll also appreciate the Overdrive's reliable components, including the precise-shifting 30-speed SRAM/Shimano drivetrain, the powerful Shimano hydraulic-disc brakes and the excellent WTB tires. Diamondback built one of the first 29er production mountain bikes and the Overdrive Comp carries that heritage with pride.
