CERAMICSPEED OSPW AERO CARBON 12S REAR DERAILLEUR CAGE SHIMANO DA9250+ULT8150

The world's fastest pulley system just got faster. It has been wind tunnel tested to have 40% less friction than a stock derailleur, making it perfect for time trials or triathlons.

OSPW Aero is an industry-leading product, developed in collaboration with one of the world's top aerodynamicists, Simon Smart, and is chosen by world champions and top athletes worldwide. This OSPW system features handcrafted CeramicSpeed bearings and its unique design and craftsmanship will win you over from the first use.

The system features a 13-tooth upper pulley and a 19-tooth lower pulley to absolutely optimize the rear derailleur. The oversized upper and lower pulleys are made of aluminum and feature CeramicSpeed coated bearings, perfected over years of experience.

The OSPW Aero for Shimano Dura Ace 9200 and Ultegra 8100 comes with an integrated stop tower for simple and durable installation.

While there are visual similarities between the OSPW series 9100 and OSPW series 9200, the spring tension settings, stop tower rotation positioning, and mounting pin depth are slightly different, therefore the systems are not compatible with each other. The Shimano R-7150 105 12-speed derailleur is not currently supported.

For 8100 derailleurs, the cage uses the factory derailleur body washer. 9200 derailleurs require the new derailleur body washer included.
