Abstract
A bicycle hub includs a hub axle, a hub body, a sprocket support member and a spacer. The hub axle has first and second portions threadedly coupled together via a first threaded connection. The hub body has an outer tubular portion and an interior passageway with the first portion of the hub axle rotatably supported therein. The sprocket support member is releasably and non-rotatably coupled to the outer tubular portion and is mounted on the second portion of the hub axle. The spacer is non-rotatably and axially movably supported on the first portion of the hub axle and is threadedly coupled to the hub body via a second threaded connection. The first and second threaded connections are configured such that rotation of the hub axle to release the first and second portions causes the spacer to move axially toward the hub body.
