Everything from bearings to the cage is made from the highest quality materials. The 17-tooth aluminium pulley wheels are fitted with standard or coated CeramicSpeed bearings, which reduce friction to the minimum. The overall power savings of the OSPW System for Shimano reach 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.
