Super Boost Rear Hub

Product Description

Bigger riders, loaded bikes, and rough terrain put greater demands on a rear wheel. This heavy-duty rear hub offers 12 × 157 mm Super Boost spacing for downhill mountain biking and demanding 32-inch-wheel mountain bike, gravel bike, and e-bike builds.

An aluminum hub body, steel axle, and four-bearing design form the core of the hub. Choose 32- or 36-hole drilling for 14-gauge J-bend spokes, with a 6-bolt disc brake mount and 58 mm flange pitch circle diameters on both sides.

For a downhill setup or a loaded large-wheel build, select the drilling that matches your wheel and confirm your frame accepts the 12 × 157 mm axle configuration.
