CERAMICSPEED – OSPW X – SHIMANO GRX 810/815 + RX800/805

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).
