Abstract (en)

[origin: WO9937529A1] The invention relates to a device for automatically actuating a bicycle derailleur with multiple gear shifting. The inventive device comprises a mechanism which regulates centrifugal force. Said regulating mechanism is rotationally arranged on the wheel axle (8), is coupled to the wheel hub on the entry side, and is coupled on the exit side to an actuating element (6) provided for multiple gear shifting. A reduction gear is arranged between the wheel hub (4) and the drive element (12) of the regulating mechanism, said drive element being located on the entry side. The movement of the regulating mechanism (16) located on the exit side is moved outward via a regulating element (76) which is arranged in the wheel axle and which can be longitudinally displaced. Said regulating element sits closely against the regulating mechanism (16) by means of a drive pin (74).
