CeramicSpeed OWSPX GRX Coated 11spd 2by

This 13-tooth upper and 19-tooth lower OSPW System has been tried and tested in races such as Paris-Roubaix, Strada Bianche and the CX World Cups.

The system is designed for gravel and cyclo-cross disciplines and meets the requirements for durability, low friction and longevity.

The four spring tension settings allow for a customised setup based on riding conditions, and the hand-built OSPW System features a custom-moulded carbon fibre cage for lightness and durability.

CeramicSpeed OSPW Systems reduce friction by 35–40 per cent compared with the standard pulley configuration.

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