The invention relates to an actuator device for a bicycle gearshift, comprising an actuation linkage, a drive member configured to control the deformation of the actuation linkage and comprising a motion transmission element (122) having a rotation axis (X), and a fastening/release mechanism (150) operatively arranged between the motion transmission element (122) and a connection rod (102) of the actuation linkage. The fastening/release mechanism (150) comprises a first member (160) rotatable about the rotation axis (X) as a unit with said motion transmission element (122), a second member (170) rotatable about the rotation axis (X) together with said connection rod (102), an elastic element (180) operatively arranged between the first member (160) and the second member (170) and that exerts a predetermined pre-load stress on the first member (160) and on the second member (170). The fastening/release mechanism (150) is selectively configurable in a fastening operative condition in which the first member (160) is rotatable about the rotation axis (X) as a unit with the second member (170), and in a release operative condition in which the first member (160) and the second member (170) can rotate with respect to one another about the rotation axis (X).
