Abstract
This invention relates to a shifter for the actuation of derailleurs on bicycles with an integrated transition distance for shifting the chain from a smaller sprocket to the next larger sprocket by means of a detent element. The detent element interacts with a detent spring which detent spring is permanently fastened to the housing. The return of the shifting system into the correct position of the derailleur over the desired larger sprocket is no longer left exclusively to the return spring of the derailleur by means of a Bowden cable, but is assisted by a transition spring which is coupled to the detent spring in the shifter.
