ABSTRACT:
The described actuation device comprises a housing, intended for attachment to the handlebars or to the frame of a bicycle, a cable-winding bobbin, angularly mobile in the housing about a main axis (X) of the device, and support means of the bobbin in the housing. Such support means comprise a first support unit at an outer guide collar of the cable-winding bobbin, situated in an intermediate position of the bobbin in the direction of the main axis (X) of the device. An excellent distribution of the stresses between the bobbin and the housing is thus ensured, substantially reducing the risks of excessive deformation and breaking.
