OSPW AERO FOR Shimano 9250 and 8150

CeramicSpeed OSPW Aero Shimano Dura-Ace 9250 / Ultegra 8150 12-speed

The world's fastest pulley wheel system just got faster. OSPW Aero has a lifetime warranty and is wind tunnel tested to have 40% less friction than a stock derailleur, making it perfect for time trials or triathlons.

The OSPW Aero is an industry leading product co-developed with one of the world's foremost aerodynamicists; Simon Smart and is chosen by world champions and top athletes around the world. This OSPW system features handcrafted CeramicSpeed bearings and its unique design and craftsmanship will captivate you from the first use.

The system features a 13-tooth upper pulley and a 19-tooth lower pulley to provide absolute rear derailleur optimization and the oversized aluminum upper and lower pulleys feature coated CeramicSpeed bearings that have been perfected over years of experience. .

CeramicSpeed OSPW Aero for Shimano Dura Ace 9200 and Ultegra 8100 has an integrated stop tower for simple installation and durability.

Please note that while there are visual similarities between the 9100 series OSPW and the 9200 series OSPW, the spring tension settings, rotation stop tower placement and pin depth mounting brackets are slightly repositioned, and as such the systems are not compatible with each other. The Shimano R-7150 105 12 speed is not supported at this time.

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