CeramicSpeed's OSPW Aero system has been developed in close collaboration with one of the world's 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. Only compatible with Dura Ace 9100/9150 and Ultegra 8000-SS/8050-SS. Not compatible with Ultegra 8000-GS or 8050-GS (medium cage) nor with the clutch equipped Ultegra RD RX800/RX805. CeramicSpeed products with coated bearings include a lifetime warranty
