WS5 C44 is a series of wheelsets built around carbon ISO 355 mm rims and Ridea HF2 hubs.
HF2 PARCA freehub is completely silent while coasting, providing quiet rides with instand engagement. HF2 (non-PARCA) includes the G72 ratchet mechanism present in Ridea road bike hubs.
These wheelsets are built with Ridea hubs specifically designed to fit Birdy bikes, but they may be also compatible with other brands that use the same OLD and hub system used by Birdy.
