ABSTRACT:
A method for carrying out gearshifting of a bicycle derailleur through an actuation device is described that utilizes a mobile mechanical member to control the derailler. Every gearshifting operation corresponds to a movement of predetermined amount of the mobile member. The method is carried out by the steps of an active initial movement of the mobile member for a first amount equal to only a portion of the amount of the movement corresponding to gearshifting; and an automatic final movement of the mobile member for a second amount equal to the remaining portion of the amount of the movement corresponding to gearshifting. Devices capable of implementing such a method are also described.
