Abstract
An electronically servo-assisted gearshift actuates a multiple gear-shifting that moves a chain from a current toothed wheel to a target toothed wheel not immediately adjacent to the current toothed wheel in a gearshift group having at least three toothed wheels. Actuating the multiple gear-shifting takes several steps (i) actuating a single gear-shifting to move the chain to a toothed wheel immediately adjacent to the current toothed wheel in the gear-shifting direction, and (ii) repeating step (i) until the immediately adjacent toothed wheel is the target toothed wheel.
