A control device for a bicycle derailleur has a supporting body that can be fixed to the handlebar and which can be gripped by the cyclist and which has an internal side wall and an external side wall, which are substantially parallel to the plane of a respective curved end of the handlebar. The device has an actuator for actuating the derailleur towards higher or lower gear ratios, controlled by means of one a first and one a second control member. The two control members are both arranged on the internal side wall of the supporting body, in a position that can be reached by the cyclist's thumb when his hand is in its normal operating position.
