The Diamondback Overdrive Sport mountain bike is a classic hardtail that takes advantage of years of development and refinement, delivering a final product that outperforms bikes twice its price. Beautifully formed tubes add strength to the aluminum frame and keep it stiff and lightweight. In true hardtail fashion the Diamondback Overdrive Sport transfers power to the ground immediately: the slightest force on the pedals travels through a 27-speed Shimano drivetrain and straight to the knobby tires, ready for quick accelerations and long singletrack grinds. A 100mm fork (with lockout) and powerful hydraulic disc brakes help you maintain control on descents and bumpy terrain. With so many features for the price the Overdrive Sport looks better than ever.
