Note; While there are visual similarities with the SRAM RED/Force AXS derailleurs, this OSPW system is not compatible with the SRAM Rival AXS derailleur.

Shimano R9250 / R8250

The system features a 13-tooth upper Pulley Wheel and a 19-tooth lower Pulley Wheel to provide absolute optimisation 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.

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

Please note while there are visual similarities in the 9100 Series OSPW and 9200 Series OSPW, the spring tension settings, rotation stop tower placement, and mounting pin depth are slightly repositioned, and as such the systems are not cross-compatible. The 12spd Shimano R-7150 105 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.
