Abstract
A variable sprocket, particularly suitable for a bicycle transmission, comprising a drive flange and an indexing flange mounted on an axle with a pair of sprocket-segment-planets and at least two idler-planets sandwiched between said flanges forming a relatively rigid variable-sprocket, the planets adapted to expand and contract in response to a relative rotation of the flanges and thereby change the effective diameter of the variable-sprocket.
