SIGNAL TRANSMITTER FOR A GEAR CHANGING APPARATUS FOR A BICYCLE

Abstract: a signal transmitter for a shifter apparatus for a bicycle. the signal transmitter includes an annular transmitter base, a sensor which generates transmitter signals, and an annular operating element which can be joined to the annular transmitter base to jointly form a feed-through opening which accommodate a bicycle handlebar. the annular operating element includes a magnet and can be held in a neutral position on the annular transmitter base by the magnet so that, starting therefrom, the annular operating element is operatable to perform a rotational movement relative to the annular transmitter base in any direction about a longitudinal axis of the feed-through opening, and to perform a tilting movement relative to the annular transmitter base. the transmitter signals generated by the sensor correspond to a specific rotational movement or to a specific tilting movement of the annular operating element.
