Diamondback's Overdrive Sport features a light, nimble aluminum frame that soars up the climbs. The SR Suntour suspension fork helps out, too. It smooths out the bumps up front for superior control. Add large 29-inch wheels that increase cornering traction and hold momentum over trail obstacles and the result is a bike that doesn't back down. The Overdrive's reliable components won't back down either. The sure-shifting 24-speed SRAM drivetrain, the powerful Tektro hydraulic disc brakes and the excellent WTB tires are ready for the trails. Diamondback built one of the first 29er production mountain bikes. Building on that experience, the Overdrive is a finely tuned mountain rig you'll love.
