CeramicSpeed OSPW Aero for Shimano 9100 and 8000 - Black

The fastest derailleur pulley system in the world has become even faster. OSPW Aero comes with a lifetime warranty and is wind tunnel tested – it reduces friction compared to a stock derailleur by 40% and is therefore ideal for time trials and triathlons.

The OSPW Aero is an industry-leading product developed in collaboration with one of the world's leading aerodynamics experts, Simon Smart. It is used by world champions and top athletes worldwide. This OSPW system features handcrafted CeramicSpeed bearings and boasts unique design and craftsmanship.

The system includes a 13-tooth upper jockey and a 19-tooth lower jockey pulley for absolute optimisation of the derailleur. The oversized aluminium pulleys are equipped with coated CeramicSpeed bearings, perfected through years of experience.

The OSPW Aero for Shimano 9100 and 8000 features an integrated stop tower for easier installation.

Note: The OSPW Aero system for 9100/9150 and 8000 SS/8050 SS is NOT compatible with Ultegra 8000-GS or 8050-GS (medium cage) derailleurs, nor with the clutch-equipped Ultegra RD RX800 & RX805.
