Ceramic Speed OSPW Derailleur for Shimano Dura Ace 9250 and Ultegra 8150

The oversized pulley wheel system for Shimano Dura Ace 9200 and Ultegra 8100 with an integrated stop tower for easy installation and durability.

The CeramicSpeed oversized pulley wheel system has been proven to be the fastest pulley wheel system in the world.

CeramicSpeed OSPW systems are an industry-leading product, chosen by world champions and top athletes around the world.

This OSPW system has hand-built CeramicSpeed bearings installed in each pulley wheel and comes with a standard 4-year warranty and a lifetime warranty when choosing coated bearings or SLT.

Equipped with a 13-tooth upper pulley wheel and a 19-tooth lower pulley wheel for complete optimisation of the rear derailleur. The oversized upper and lower aluminium pulley wheels feature standard or coated CeramicSpeed bearings.

Please note that although the 9100 OSPW series and the 9200 OSPW series look similar, the spring tension settings, rotation stop tower position and mounting pin depth are slightly repositioned, so the systems are not compatible with each other. The Shimano R-7150 105 12-speed is not currently supported.

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

In the box:

• One complete 13 denti/19-tooth OSPW system
• CeramicSpeed pulley wheel bearing oil, 15 ml dropper bottle
