The invention relates to an actuation device for actuating the front derailleur of a bicycle, comprising a control pin, configured to be set in rotation by a control lever, rotatable about a rotation axis in a first angular direction between the first and last angular positions and in a second angular direction between the last and the first angular positions. A cable-winding bush rotates between the first and last winding positions. An indexer has a plurality of stop areas corresponding to angular positions between the first and the last angular positions. Elastic members makes the control pin form a unit with the cable-winding bush during rotations of the cable-winding bush between and among the various winding positions and to make the control pin rotatable with respect to the cable-winding bush between the last winding position of the cable-winding bush and the last angular position of the control pin.
