Pedals featuring a back-side hexagon broach are now standard on many modern bicycles in 6 and 8mm sizes. Crank bolts are also commonly 8mm and often require high torque. This 8mm hex pedal/crank driver was specifically designed for quick-and-easy pedal and crank installation and removal. Features include an ergonomic dual-density screw driver handle for comfort and control, an extra long hex key for exceptional leverage, a second ball end for quick and easy installation or removal, and heat-treated S2 tool steel construction for the ultimate in strength and long-lasting performance. Backed by Pedro's lifetime warranty.
