ABSTRACT:
A device for controlling a bicycle derailleur comprises a control member which is rotatably mounted on the handlebar adjacent to a fixed handgrip. The various operative positions of the rotatable control member are defined by indexing means comprising a toothed wheel which is rigidly connected to said rotatable control member and a plurality of resilient engagement members carried by said supporting body and able to selectively engage the vanes between the teeth of the toothed wheel. The supporting body has a C-shaped configuration with two wings which can be clamped by a screw which is also used to rotatably support a pulley on which the flexible control cable actuated by the rotatable control member is engaged.
