CeramicSpeed OSPW System – Shimano 9100

This CeramicSpeed Oversized Pulley Wheel System is developed for performance optimisation, and the watt savings start at 2.4 watts. The cage is made from carbon fibre and reinforced PA while the pulley wheels are made from aluminium and mounted with high-quality CeramicSpeed bearings. Specifically designed for Shimano 9100/91500, and suited to both training and racing, this Oversized Pulley Wheel system will perform better for longer, lasting three to five times longer than standard pulleys.

Shimano Specific Pulley Wheels

Because of the design of the 9100 derailleur, the R&D team at CeramicSpeed tested and concluded that the best performing combination of oversized pulleys for the Shimano 9100 series is a 13-tooth upper and 19-tooth lower pulley. The design of this Shimano-specific OSPW System is very strong and stiff to ensure a high durability factor. In-house tests show that the higher the tooth count, the longer pulley wheel lasts.

Optimum Performance

This revolutionary OSPW System is developed, produced and assembled by hand in Denmark. Designed to be a plug-and-play fit, it’s the result of an in-depth development process and has been finely tuned to provide optimal performance. Created to answer the need for less friction (as much as 60%), increased speed and a more efficient drivetrain, the OSPW System gives back what other drivetrains take: watts.

It?s important that you properly lubricate your bearings in order to ensure optimal performance and maximum longevity. Add oil to the outside of the bearing seal, so that oil can penetrate the bearing. Do this when you lubricate your chain, or if you have washed your bike or have been riding in wet or muddy conditions.
