The evolutionary Oversized Pulley Wheel System delivers maximum drivetrain performance and enhances power transfer from rider to the road. This easy to install system boosts your cycling enjoyment and effectiveness at all speeds thanks to its smooth and consistent function with mechanical SRAM rear derailleurs.
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 Oversized 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.
