The invention relates to an actuation device (10) for actuating the front derailleur of a bicycle, comprising a control pin (12), configured to be set in rotation by a control lever, rotatable about a rotation axis (X) in a first angular direction (A) between a first angular position and a last angular position and in a second angular direction (B) between the last angular position and the first angular position, a cable-winding bush (13) angularly rotatable about the rotation axis (X) to wind a control cable between a first winding position and a last winding position and vice-versa, an indexer (11) configured to define a plurality of stop areas (20) for the rotation of the control pin (12), each area (20) corresponding to an angular position comprised between the first angular position and the last angular position of the control pin (12). Elastic members (21) are active between the control pin (12) and the cable-winding bush (13) and are configured to make the control pin (12) form a unit with the cable-winding bush (13) during rotations of the latter between the first winding position and the last winding position and between the last winding position and the first winding position and to make the control pin (12) rotatable with respect to the cable-winding bush (13) between the last winding position of the cable-winding bush (13) and the last angular position of the control pin (12).
