What is Coated?

Our coated products have a 6 years warranty. The unique coating formula is a metallic layer that covers the bearing races and makes them 75% harder than steel. Thanks to this, they are highly resistant to corrosion and the coating provides an even lower friction than our standard bearings. Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible if you choose the coated version.


OSPW X for Shimano GRX/RX 2x11

This 13-tooth lower and 19-tooth upper OSPW System has been platform proven at races like Paris Robaix, Strada Bianche and CX World Cups. The system is built for gravel and cross disciplines and meets the needs for durability, low friction and longevity.

The four spring tension settings allow customised setup based on ride conditions, and the handbuilt OSPW System offers custom molded carbon fiber cage for lightweight and durability. CeramicSpeed OSPW Systems reduces friction 35-40% over stock pulley configuration.

Only compatible with 2X systems. Not compaitble with 42-tooth cassettes.

Maintenance of CeramicSpeed OSPW Systems

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.
