CeramicSpeed OSPW System R9250-R8150

Chosen by World Champions and top athletes around the world, the CeramicSpeed Oversized Pulley Wheels System has been proven to be the fastest pulley system in the world. Featuring an industry-leading design, this limited edition model is for Shimano Dura Ace 9200 and Ultegra 8100 systems with an integrated stop tower for simple installation and durability.

This OSPW System has hand built CeramicSpeed Bearings installed in each pulley and it comes with a four year CeramicSpeed warranty as standard and a lifetime CeramicSpeed warranty when choosing coated bearings (please choose option from the menu).

Limited Edition Shimano R9250/R8150 OSPW System

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.

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