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

The CeramicSpeed Oversized Pulley Wheels System has been proven to be the fastest in the world.

CeramicSpeed OSPW Systems are an industry-leading product chosen by World Champions and top athletes worldwide.

This OSPW System has handbuilt CeramicSpeed Bearings installed in each pulley and comes with a four-year warranty as standard and a lifetime warranty when choosing coated or SLT bearings.

They feature a 13-tooth upper pulley wheel and a 19-tooth lower pulley wheel to optimize the rear derailleur. The upper and lower oversized aluminum pulley wheels come with standard or coated CeramicSpeed Bearings.

Please note that 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 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. Nine thousand two hundred derailleurs will require the new included derailleur body washer.

In The Box

• A complete 13-tooth/19-tooth OSPW System
• CeramicSpeed Oil for Pulley Wheel Bearings, 15ml. Dropper bottle.

Maintenance of CeramicSpeed OSPW Systems
Regarding the maintenance of your OSPW System, it is essential that you properly lubricate your bearings to ensure optimal performance and maximum longevity. Add oil by using the lubrication points on the back cage plate so that oil can penetrate the bearing. Do this when you lubricate your chain, if you have washed your bike or after riding in wet or muddy conditions.
