ABSTRACT:
An incrementally variable transmission, particularly suitable for a bicycle, having a variable-sprocket which comprises: A drive-flange and an indexing-flange mounted on an axle with a pair of sprocket-segment-planets and at least a pair of idler-planets sandwiched between the flanges, the planets adapted to expand and contract in response to a relative rotation of the flanges and thereby increase and decrease, respectively, the effective diameter of the variable-sprocket.
