Campagnolo OS Freehub Body

Compatible with the classic ball-bearing hubs of Campagnolo wheelsets featuring a 17 mm axle and a 30 mm diameter pawl housing.

This freehub body is also compatible with Fulcrum hubs with a 17 mm axle

These freehub bodies are designed for 17 mm diameter axles and are therefore not suitable for Campagnolo wheelsets with industrial bearings. These require freehub bodies for 12 mm axles. The new Campagnolo WTO and Shamal Carbon Disc wheelsets have a larger pawl housing (33 mm). These freehub bodies are not suitable for these either.
