ABSTRACT:
A control body is provided for mounting to a bicycle in close proximity to a handlebar for controlling a pulling and releasing of the transmission element. A first lever is mounted to the control body for movement which causes the control body to effect pulling of the transmission element, and a second lever is mounted to the control body for movement which causes the control body to effect releasing of the transmission element. The first lever and the second lever are mounted to the control body so that the handlebar is disposed between the first lever and the second lever when the shifter operating device is mounted to the bicycle. In a first embodiment both levers may be pivotally coupled to the control body for movement in a common plane, and the first lever may be adapted to move in a direction opposite to the movement in the second lever. In a second embodiment one lever may be pivotally coupled to the control body and the other lever may be coupled for linear movement relative to the control body.
