The CeramicSpeed OSPW System for Shimano 9100/9150 and 8000 SS/8050 SS is designed to reduce drivetrain friction by 35–40% compared to stock pulley setups. This updated version includes an integrated stop tower, making installation smoother and improving shifting precision under demanding race conditions.
Oversized Pulleys for Proven Efficiency Gains: Featuring a 13-tooth upper pulley and a 19-tooth lower pulley, the system optimizes chain articulation for significant energy savings—starting from 2.4 watts over standard Shimano pulleys. Both wheels are machined from lightweight aluminium and fitted with CeramicSpeed Standard or Coated Bearings for enhanced longevity.
Customisable Spring Tension for Perfect Setup: The OSPW design allows riders to adjust spring tension based on terrain and riding style. This customisation improves chain stability during accelerations and descents, providing a personalised feel suited to racing, time trials and high-performance road riding.
Lightweight Carbon Cage for Strength and Durability: Built with a custom-moulded carbon fibre cage, the OSPW system achieves remarkable stiffness while keeping overall weight to a minimum. The carbon construction maintains alignment under load, ensuring crisp shifting and consistent chain engagement in all conditions.
Compatibility for Shimano 9100/9150 & 8000 SS Only: This OSPW system is compatible with Dura-Ace 9100/9150 and Ultegra 8000 SS/8050 SS derailleurs up to a 32T cassette.
Note: It is not compatible with Ultegra GS, RX800/805 clutch derailleurs, or Shimano 12-speed systems.
