Abstract
A twist-grip shifter for bicycles having a twist grip or grip part which is actuated by the rider's hand to change the gears of the bicycle, and a cable winding mechanism or coil wind-up mechanism. The twist grip and the cable winding mechanism of the twist-grip shifter can be connected to one another by providing claws or projections on a tubular extension of the cable winding mechanism, and by providing corresponding recesses inside the twist grip, in which recesses the claws can be engaged. One of the claws and one of the recesses can be configured differently from the other claws and recesses, in order to simplify the assembly of the two parts with respect to one another.
