The disclosed device controls a cable associated with a bicycle gearshift and is particularity configured for securing the body of the device on the forward-facing end of racing bicycle handlebars. A cable winding bobbin, having an internally toothed crown, is provided in the device's body and a drive mechanism rotates the bobbin in the chosen direction to achieve predetermined angular positions. A ratchet mechanism, located between the lever and the toothed crown, includes opposite rocker arms with cam profiles curved away from each other, and a toothed sector for engaging the toothed crown. A pointer is located to be selectively engaged with at least one of the rocker arms so that engagement results in the rocker arm's toothed section being away from the toothed crown, and disengagement results in the rocker arm's toothed section being engaged with the toothed crown.
