ABSTRACT:
A bicycle unit hub incorporates a hub shell rotatably supported on a hub shaft, a core mounted to one end of the hub shell for co-rotation therewith, a sprocket carrier supported around the core to rotate relative thereto only in one direction, and a hollow bolt inserted into the hub shell from the other end thereof. The bolt has a head engageable with an annular step formed on the hub shell. The bolt also has a threaded tip portion for engagement with an internally threaded portion of the core or a nut, so that the hub shell is clamped between the bolt head and the core with resultant fixation of the core.
