Description

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. Ceramic Speed OSPW Systems reduces friction 35-40% over stock pulley configuration.

Only compatible with the '2X-specific' GRX 810, GRX 815, as well as the RX800, and RX805 derailleurs. If you are using a 1x you can use a 36T cassette maximum.
