Abstract
A shift device for actuating at least one gear mechanism on a bicycle, comprising a housing for securing the shift device on the bicycle, a grip element for actuating the shift device, a rotary element and a cable storage device, in particular a spool for winding up a cable to actuate the gear mechanism where the rotary element is connected to the spool and has at least one detent pawl which engages in detent toothing of the housing. It is advantageous that the drive feature on the grip element takes the rotary element along directly in one direction of rotation, whereas the movement of the rotary element in the opposite direction of rotation is effected by release of the detent pawl.
