The OSPW System for Shimano is compatible with Shimano 9100/9150 and Ultegra R8000 groupsets. Developed and designed entirely by CeramicSpeed, the Oversized Pulley Wheel System is advanced for the optimization of bike performance, where the watt savings start at 2.4 watts. Everything from bearings to the cage is made from the highest quality materials. The 17-tooth aluminium pulley wheels are fitted with CeramicSpeed Bearings, which reduce friction to the minimum. The overall power savings of the OSPW System reaches 60% or more in some cases. The OSPW System has a lifetime that lasts 3-5 times longer than the commonly used standard pulleys on the market.
