Description
CeramicSpeed OSPW Pulley Wheel Aero System for Shimano 9100/9150 and 8000 SS/8050 SS - Coated Races Alloy Pulley Carbon Cage Black. CeramicSpeeds OSPW Aero system has been developed in close collaboration with one of the worlds leading aerodynamicists. The development process behind the OSPW Aero spanned over two years where extensive wind tunnel testing influenced multiple design iterations. The end result is an entirely new cage structure wrapped around our existing mechanically optimized design.
