<p>A shifter operating device (5) includes a control body (70) for mounting to a bicycle in close proximity to a handlebar (1) for controlling a pulling and releasing of the transmission element (4). A first lever (20, 20') is mounted to the control body (70) for movement which causes the control body (70) to effect pulling of the transmission element (4), and a second lever (30, 30') is mounted to the control body (70) for movement which causes the control body (70) to effect releasing of the transmission element (4). The first lever (20, 20') and the second lever (30, 30') are preferably mounted to the control body (70) so that the handlebar (1) is disposed between the first lever (20, 20') and the second lever (30, 30') when the shifter operating device (5) is mounted to the bicycle. In a first embodiment both levers (20, 20'; 30, 30') may be pivotally coupled to the control body (70) for movement in a common plane, and the first lever (20, 20') may be adapted to move in a direction opposite to the movement in the second lever (30, 30'). In a second embodiment one lever (30) may be pivotally coupled to the control body and the other lever (20) may be coupled for linear movement relative to the control body (70). <IMAGE></p> |
