Product Details

The Overdrive Sport 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 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. Now with 27.5” wheels, the Overdrive Sport is quicker than ever.

Hand built 6061-T6 aluminum alloy hardtail frame for classic simplicity
Custom formed and butted tubing balances stiffness and weight savings
SR Suntour 100mm fork gives just the right amount of suspension
SRAM 8-speed drivetrain offers gears for any terrain
27.5” wheels roll well over obstacles and offer quick handling
