Abstract
The device permits the control of a derailleur by means of a lever (9) with the use of indexation means which ensure a precise positioning of the lever in the various positions corresponding to the various gear ratios. It also permits the adjustment of the indexation pitch, so as to adapt it to freewheels having a different spacings or pitches between different sprocket pinions. For this purpose, positioning elements (19) may be shifted by a pitch selection element (21) so that the pitch between the various positions of the lever is modified.
