An apparatus for operating a bicycle transmission shifting device having an operating component (10) for mounting to a bicycle in close proximity to a brake operating unit for alternately pulling and releasing a transmission element, a first lever (26) is mounted to the operating component (10) for movement which causes the operating component (10) to pull the transmission element and second lever (34) is mounted to the operating component (10) for movement which causes the operating component (10) to release the transmission element. The first lever (26) and the second lever (34) are mounted to the operating component (10) so that the brake operating unit is disposed between the first lever (26) and the second lever (34) when the shifting device is mounted to the bicycle. In order to be able to construct the shifting device with only a single pawl (98) for the release mechanism the takeup element for the transmission element includes a control member (72) having a plurality of large and small position retaining teeth (80a-80c) and (82a-82f) for engaging the single release pawl (98). <IMAGE> |
