Abstract
A hub assembly for a bicycle wheel comprises a tubular body part having two spaced flanges for connection to the spokes of the wheel. A tubular sprocket carrier support extends from one end of the body part, and surrounding the sprocket carrier support is a carrier on which axially spaced toothed sprockets are mounted. The carrier is rotatable in one direction relatively to the hub to provide a free-wheel. The bearing between the carrier and the support is a plain bearing to minimise the diameter of the carrier and support, and thus permit smaller sprocket wheels to be employed. The hub bearing sets are so dimensioned that they may both be inserted from the same end of the body part.
