Abstract
This invention relates to a latching shifter for bicycle transmissions, such as hub transmissions or derailleurs, with a housing, a latch element with notches, a latching spring with a latching lug and two projections, as well as a slide with different bias stages which interact with the projections of the latching spring. By changing the position of the slide, the projections of the latching spring are brought together with different bias stages of the slide, whereupon the latching spring is pressed with varying degrees of pressure by means of its latching lug into the notches of the latching element. The advantage of the externally adjustable bias is that the shifter can be individually adjusted in terms of the retention force which prevents unintentional shifting when the bicycle is in motion.
