<p>A bicycle speed control apparatus according to this invention comprises a wind-up control device including a take-up element (21) for winding a speed control cable, and a position maintaining mechanism (3) for maintaining the take-up element in position. The control device is operable to effect change speed by rotating the take-up element (21) for winding the cable. The present invention is characterized in that the position maintaining mechanism (3) is operable to maintain the take-up element (21) in a plurality of change speed positions and in overshift positions displaced from the change speed positions in a cable winding direction, respectively. The invention further provides a position maintenance canceling device (4) operable to release the take-up element (21) maintained in position by the position maintaining mechanism (3), and to limit an amount of rotation of the take-up element (21) in the rewinding direction to one change speed position when the take-up element (21) has been maintained in one overshift position associated therewith.</p> |
