Abstract: A multi-speed free-wheel sprocket support ring having two ball races for connecting the ring to an interior starwheel, and ratchet teeth intended to interact with spring clicks supported by the starwheel, said support ring is formed by at least one thin-walled tubular member (2,3). The ball races (7,10) and the toothing (9) are formed by deformations of the wall of the member.

Abstract: Bicycle free-wheel ring (1) possessing an inner surface equipped with a ball race for a row of balls in the vicinity of each of its ends and with splines (9) in the form of ratchets in an approximately central zone, and an outer surface (11) intended to receive at least two sprockets. This outer surface is of circular section and possesses at least one smooth sprocket-reception zone. The sprockets (12) have a bore corresponding to the smooth zone of the outer surface of the ring, to which they are fixed by welding, soldering, bonding or expansion.
