This OSPW System has handbuilt CeramicSpeed Bearings installed in each pulley and it comes with a four-year manufacturer's warranty as standard. Featuring a 13-tooth upper pulley wheel and a 19-tooth lower pulley wheel to provide absolute optimisation of the rear derailleur.

The CeramicSpeed Oversized Pulley Wheels System has been proven to be the fastest pulley system in the world. With an industry-leading design, the CeramicSpeed OSPW System is the choice of World Champions and top athletes around the world.
The overall power savings of the OSPW System for Shimano 9200 reach 30%-60%, or more in some cases, over a stock setup. The oversized pulley wheels have a 3-5 times longer lifetime than the commonly used standard pulleys on the market.
Regarding the maintenance of your OSPW System, it is important that you properly lubricate your bearings in order 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.
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.
