WS6 A33 is a series of wheelsets built around alloy ISO 406 mm rims. They are available with two different hubs (rim and disc brake options) and four rim colors.
HF1 and HF2 hubs include 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.
