ABSTRACT:
A method for electronically servo-assisting a bicycle gearshift to allow compensation for misalignments between the chain of a bicycle gearshift and one or more sprockets of the gearshift, the method including the steps of: driving an actuator of a bicycle gearshift to displace a chain of the gearshift in an axial direction with respect to a gearshift group comprising at least two sprockets; receiving information on the desired alignment between the chain and a predetermined sprocket of the gearshift group; and setting an adjustment variable, of a logic value associated with the gear ratio relative to the predetermined sprocket, to a value corresponding to the displacement carried out in the step of driving the actuator.
