Abstract
A twist-grip switch for the actuation of bicycle gears is arranged in the grip region of a handlebar is fixed thereto by a clamping clip. The switch components, such as the grip end piece, twist-grip part, winding reel and switch housing, are arranged around the central bearing tube and form a complete grip unit. The bearing tube fits tautly on the handlebar and on one side is rigidly connected to the grip end piece by an overmolding connection and on the other side is fixed to the switch housing by means of a snap connection. The clamping clip prevents the snap connection from being opened in the mounted state. Furthermore, the grip end piece reliably assumes the intended position on the handlebar tube in relation to the switch housing, and it cannot be removed from this position by forces acting on it.

- a shifter housing secured to the handlebar tube;
- a bearing tube connected to said shifter housing such that said bearing tube is fixed with respect to rotation and axially nondisplaceable relative to said shifter housing;
- a winding reel rotatably arranged in said shifter housing and on said bearing tube for actuating the cable assembly;
- a twist-grip part rotatably arranged on said bearing tube and actuatable for rotation about said bearing tube, said twist-grip pan being connected to said winding reel such that said winding reel rotates with said twist-grip part;
- and
- a grip end piece fixedly connectable relative to the handlebar rube, at least a portion of said grip end piece directly mounted to said bearing rube such that said grip end piece is axially and rotatably nondisplaceable relative to said shifter housing.
