As with most 1x front chainrings the pulley wheels are designed
with a wide/narrow pattern of alternating tooth profiles, so that
they mesh perfectly with the chain, further increasing chain
retention on the roughest surfaces.
A carbon fibre pulley cage keeps things strong, light, and most
importantly super stiff, to ensure precise shifting.
Each OSPW is handbuilt by CeramicSpeed in Denmark.
The OSPW X is available now, with a choice of standard or coated
bearings. To check compatibility and order contact us - we can also arrange fitting and setup
in our workshop.
