Abstract
A bicycle hub includes a hub axle, a hub body and a sprocket support member. The hub axle has first and second portions releasably coupled together. The hub body has an outer tubular portion, a first engagement portion coupled to the outertubular portion and an interior passageway. The first portion of the hub axle is rotatably supported in the interior passageway. The first engagement portion is formed with a first meshing surface. The sprocket support member is mounted on the second portion of the hub axle and has a second engagement portion formed with a second meshing surface non-rotatably engaged with the first meshing surface. The first and second meshing surfaces are so dimensioned to overlap to prevent axial separation without relative rotation occurring between the first and second engagement portions.
