The evolutionary Over Sized Pulley Wheel ystem provides a massive increase in drivetrain efficiency, ensuring each pedal rotation of power that you put down is transferred directly to the road. This easy to install upgrade is a noticeable performance enhancer from the first pedal stroke and is sure to have you riding faster, for longer.
The CeramicSpeed OSPW system is the industry-leading upgrade that top-level cyclists demand and is equally suited to aspiring road racers who want more performance output during every ride.
This version of the Over Sized Pulley Wheel system features coated bearings, which means the bearings have been treated with a special, thin layer coating system. This coating ensures prolonged bearing life, lower friction and means the bearing race is exceptionally resistant to corrosion.
