The OneUp Rear Hub is a 220 g Boost rear hub with a 44 point ratchet drive. The drive ring is machined into the hub shell, so there is no threaded ring to fail.

What it's for

A rear hub for custom trail and enduro wheel builds.

How it works

Ratchet drive: two 44 tooth ratchet rings engage every 8.2 degrees.

Wide spaced ABEC 5 cartridge bearings reduce wear and side loading.
