CeramicSpeed OSPW derailleur arm, Shimano 9100/9150 and 8000 SS/8050 SS, gold
This is an updated version of the oversized pulley system for Shimano 9100/9150 and 8000 SS/8050 SS. This new design has an integrated stop tower for easier assembly. The CeramicSpeed Oversized Pulley Wheels System has proven to be the fastest pulley system in the world, providing energy savings of as little as 2.4 watts compared to standard Shimano systems. The OSPW system for Shimano 9100/9150 and 8000 SS/8050 SS is an industry-leading product, chosen by many of the world's leading teams and professional athletes. It features a 13-tooth upper pulley and a 19-tooth lower pulley, providing absolute rear derailleur optimization. The upper and lower oversized aluminum pulley wheels are equipped with either standard or coated CeramicSpeed ceramic bearings. Note: The OSPW 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. You can find a compatible version of the RX800 and RX805 in our OSPW X for Shimano RX800/805. A compatible upgrade for Ultegra 8000-GS or 8050-GS can be found in our Shimano, 11s NW pulley wheels. While there are similarities in design, this OSPW is not compatible with Shimano 9200 or 8100 series 12-speed derailleurs. The Shimano 9100/8000 OSPW system is compatible with up to a 32-tooth cassette for both Dura Ace and Ultegra derailleurs. Included: Complete OSPW for Shimano 9100/9150 and 8000 SS/8050 SS CeramicSpeed Oilings for roller bearings. 15 ml dropper bottle
