Rear hub Bubba 28T Micro Spline

The new SUNRinglé Bubba 12x148 28T Micro Spline hub features Clock'D double-ring ratchet technology. This technology allows the rider to easily modify the degree of wheel engagement, from 8° for intensive use in eMTB or DH practice, to 4° ultra rapide for more technical riding. The hub is forged and machined in 6061 aluminum for greater lightness, and the axle in 7075 aluminum for greater strength. Maintenance is simplified by the use of press-fit hub ends and one-size-fits-all wheel bearings (6902).
