Abstract
An index shifter for a bicycle transmission, which index shifter is mounted on a part of a bicycle and has a casing, a locking element with notches which is connected to a rotary hand grip, and a winding drum for actuating a cable pull. The casing has a ring-shaped recess disposed therein, in which recess a detent spring is arranged. The detent spring is braced by two feet against the casing and has a lug which engages with the locking ring. Inside the casing is a casing projection with which one foot of the detent spring can be fixed to achieve a small amount of shift play. This permits small amounts of shift play, in particular for shifting hub gears on bicycles.
