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.

Control device for a bicycle derailleur, comprising a control member which is to be rotatably mounted on a handlebar of the bicycle adjacent to a handgrip fixed to one end of the handlebar and connected to a reel for winding a flexible cable for controlling the derailleur, and indexing means able to provide a reference of the various operative positions of the rotatable control member corresponding to respective operative positions of the derailleur,
- wherein said indexing means are constituted by a toothed wheel rigidly connected to the rotatable control member and cooperating with a resilient engagement member carried by a supporting body fixed to the handlebar and able to selectively engage the vanes between the teeth of said toothed wheel to provide a snap-type reference of the operative positions of the rotatable member,
- wherein said supporting body freely rotatably supports a pulley on which said flexible control cable is engaged, wherein said supporting body has a general C-shaped configuration, to clamp the handlebar, with two wings engaged by a clamping screw, said screw being also used to rotatably support said pulley.
