CeramicSpeed OSPW Aero Coated derailleur arm, Shimano 9100/8000, black
The world's fastest pulley wheel system just got faster. The OSPW Aero has a lifetime warranty and is wind tunnel tested to have 40% less friction compared to a derailleur, making it ideal for time trials or triathlons. OSPW Aero is a cutting-edge product developed in collaboration with one of the world's leading aerodynamicists; Simon Smart and is chosen by world champions and top athletes from around the world. This OSPW system has hand-crafted CeramicSpeed bearings installed, and its unique design and craftsmanship will captivate you from the first use. The system features a 13-tooth upper pulley and a 19-tooth lower pulley, providing absolute rear derailleur optimization, and the upper and lower oversized aluminum pulleys are equipped with coated CeramicSpeed ceramic bearings that have been perfected through years of experience. The OSPW Aero for Shimano 9100 and 8000 has an integrated stop tower for easier assembly. This is an updated version of the oversized pulley system for Shimano 9100/9150 and 8000 SS/8050 SS. Note: The OSPW Aero system for 9100/9150 and 8000 SS/8050 SS is NOT compatible with Ultegra 8000-GS or 8050-GS (middle cage) derailleurs, nor with the Ultegra RD RX800 & RX805 clutch.
