This 13-tooth upper and 19-tooth lower 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 reduce friction by 35-40% over the stock pulley configuration.

Only compatible with the ‘2X-specific’ GRX 810 and GRX 815 derailleurs, as well as RX800 and RX805 derailleurs.

You may setup the derailleur as a 1X or 2X system, to be used with up to a 36-tooth cassette.

This OSPW System is developed and designed in Denmark and comes with a 4 year warranty (standard) and a lifetime warranty (coated).

 The Coated Advantage

The coating is a metallic layer, which is 75% harder than the hardened steel races. The coating is applied in a very thin and even layer of 3 microns (0,003 mm) on the entire surface of the bearing race. Both the inside and the outside are treated to achieve optimal results.

Within our comprehensive R&D program, the special coating has been developed in cooperation with a European coating specialist. Applied to the bearing’s steel races, through an advanced process that ensures an even, smooth and homogeneous surface, the coating formula improves even further the high quality of CeramicSpeed Bearings.

Thanks to the coating’s high resistance to corrosion – even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible. We recommend choosing CeramicSpeed Coated Bearings for unmatched longevity and incredibly low friction.
