Abstract
A shift mechanism for a bicycle gear assembly that includes an actuating part that may be moved by an actuating lever or a release lever to shift between the gears of the gear assembly. The actuating and release levers operate independently from each other. The actuating part has a winding groove for receiving a cable connected to the gear assembly and first and second toothed segments. The release lever controls a detent element having first and second detent noses that are alternately engageable with the first and second toothed segments, respectively. The release lever may also have a cam contour that allows at least two gears to be shifted upon actuation of the release lever.
