Abstract
The invention relates to a twist grip shift which is arranged preferably in the grip region of a handle bar, is secured with a clip and has the purpose of activating bicycle transmissions. The shift components such as the grip end part, the twist grip part, the take-up reel and the shift housing are arranged about a central bearing tube and form one complete grip unit. The clip prevents a releasable connection between the bearing tube and the shift housing from opening in the mounted state. The advantage of this shift design lies in the increase in protection against undesired release of the releasable connection. The components which are joined in the premounted state are securely lined up on the bearing tube.
