Compatibility & fit

Rear-specific hub for a 157x12mm Super Boost frame only – check your frame's rear-end spacing before ordering. This build takes a MicroSpline cassette; SUNringlé also lists Shimano HG freehub bodies for the Bubba X, sold separately so you can swap standards later. 32-hole flange for building to a 32-hole rim. The Tune workshop can build it into a wheel or fit it to an existing rim.
