The present invention relates to a bicycle dual control device (1) hydraulically operated, so that using one single device the cyclist may operate, by applying different hand pressures or taps from the handlebar (0), two unidirectional control mechanisms, preferably a brake and a bicycle gear-shifting mechanisms. Said control device comprises two unidirectional control units (10, 20) within a single lever or handgrip attached to the handlebar, wherein each one of them comprises an acting member (11, 21), an operating member (16, 26) connected to a control circuit and a coupling element which links the two previous members. In a preferred embodiment of the invention, the operating member related to the gear shifting is hydraulic and comprises a piston and a cylinder mounted integrated inside the brake acting member. |
