Abstract
A control device for the gear change of a bicycle comprises a single operating lever, preferably provided with two distinct arms for the gear change up shifting and down shifting, respectively, to which a ratchet mechanism is associated. The ratchet mechanism comprises a pair of opposed teeth adapted to cooperate with a ratchet wheel which is associated to a control rotor. In the application on a racing bicycle, the control rotor is rotatably mounted around an axis parallel to the longitudinal direction of the bicycle.
