Rear hub Bubba X 32T XD

The SUNRinglé Bubba X 12x148 28T Micro Spline hub is the perfect hub for your wheel assembly. The ratchet ring is mounted on the hub body using keys rather than threads to facilitate maintenance and improve reliability, especially when the hub is subjected to heavy pedaling torque. With only 4 degrees of engagement, the Sun Ringlé Bubba X hub reduces pedaling dead travel for faster relaunching.
