CeramicSpeed adds Shimano-compatible version to its OSPW-X off-road pulley system

CeramicSpeed's oversize pulleys offer 30% to 40% lower friction in the rear mech than standard jockey wheels

Back in January, low friction bearing specialist CeramicSpeed launched its OSPW-X off-road pulley system. As well as CeramicSpeed’s bearings, this also features oversized jockey wheels with a wide/narrow tooth profile to mesh more closely with the two link widths in the chain. There’s also a new lightweight carbon fibre mech cage.

Now there’s a new version, compatible with Shimano’s Ultegra RX mechanical and Di2 clutched rear mechs, alongside the SRAM Force 1 and Rival 1 compatible versions announced in January. All are hand built in Denmark.
