Abstract
A method for electronically servo-assisting a bicycle gearshift, including the steps of: a) 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; b) receiving information on the desired alignment between the chain and a predetermined sprocket of the gearshift group; and c) setting a biunique correspondence between the physical position of the actuator at step b) and a logic value associated with the gear ratio relative to the predetermined sprocket.
