CeramicSpeed OSPW Aero Shimano 9250/8150 coated black

The Oversized Pulley Wheel System for Shimano Dura Ace 9200 and Ultegra 8100 with integrated stop tower for simple installation and durability.

The world's fastest pulley wheel system just got faster...
Our winning mentality and innovative DNA make us constantly strive to further develop and perfect our products. It's this relentless approach that has seen the new CeramicSpeed OSPW Aero come to fruition.



Featuring a 13-tooth upper pulley wheel and a 19-tooth lower pulley wheel to provide absolute optimisation of the rear derailleur. The upper and lower oversized aluminium pulley wheels come fitted with either standard or coated CeramicSpeed Bearings.

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.
