An actuator device for a bicycle gearshift includes an actuation linkage, a drive member configured to control the deformation of the actuation linkage and comprising a motion transmission element having a rotation axis (X), and a fastening/release mechanism operatively arranged between the motion transmission element and a connection rod of the actuation linkage. The fastening/release mechanism has a first member rotatable about the rotation axis (X) as a unit with said motion transmission element, a second member rotatable about the rotation axis (X) together with said connection rod, an elastic element operatively arranged between the first member and the second member and that exerts a predetermined pre-load stress on the first member and on the second member.
