The OSPW System for SRAM is compatible with SRAM eTap groupsets. Developed and designed entirely by CeramicSpeed, the Oversized Pulley Wheel System for Shimano 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 coated CeramicSpeed Bearings, which reduce friction to the minimum. The overall power savings of the OSPW System for SRAM eTap 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.
IMPORTANT: When travelling, please remember to dismount your entire rear derailleur with an Allen key, as the OSPW System will not fit in most bike travel bags and could be damaged if left on.
