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.Locally reduces drag by an average of 40% compared to stock derailleurs
Developed in coordination with Drag2Zero
Refines aerodynamics by focusing on frontal area impact as well as smoothing and controlling the trailing wind
Features 13-tooth upper and 19-tooth lower aluminum pulley wheels with Grade 3 Silicon Nitride balls
Robust cage crafted from polyamide and carbon fiber for durability and light weight
Coated bearing races increase bearing service life by increasing hardness of race and reducing corrosion

Not compatible with Ultegra 8000-GS or 8050-GS (medium cage) nor with the clutch equipped Ultegra RD RX800/RX805
