The CeramicSpeed OSPW Aero features a lifetime warranty and is wind-tunnel tested to have 40% less friction compared to a stock derailleur, making it perfect for time trials or triathlons, and this version for Shimano Dura Ace 9200 and Ultegra 8100 has an integrated stop tower for simple installation and durability.
The system features a 13-tooth upper Pulley Wheel and a 19-tooth lower Pulley Wheel to provide absolute optimization of the rear derailleur and the upper and lower oversized aluminum Pulley Wheels come fitted with coated CeramicSpeed Bearings that have been perfected through years of experience.
