The invention relates to an actuation device (10) of the control cable of a bicycle gearshift comprising a casing (11), a cable-winding bush (13) mounted in the casing (11) rotatable about a rotation axis (X) in a first angular direction (A) between a first and a last angular position and in a second angular direction (B) between the last and the first angular position, a rotary member (14) mounted in the casing in a rotary manner about the rotation axis (X) and a stationary member (18) mounted in a non-rotary manner in the casing (11), wherein one from the two members is provided with at least one first pointer (15) engaged on a fastening track (19) formed on the other member, the fastening track (19) extending along a closed loop path and comprising at least one first plurality of stop positions (20) engageable in sequence by the pointer (15), the cable-winding bush (13) passing from one angular position to an adjacent angular position following the passage of the pointer (15) from one stop position to an adjacent stop position, each stop position being angularly spaced from an adjacent stop position by a respective indexing angle (C), a first stop position (20a) that determines the first angular position of the cable-winding bush (13) being angularly spaced from the next stop position (20b) by an indexing angle (C) equal to the indexing angle (C) necessary to make the cable-winding bush (13) rotate from the penultimate angular position to the last angular position.
