Abstract
A device for operating the gear change of a bicycle comprises a main body mounted rotatably on a support pin and provided with an operating lever. A member driven by the main body and whose rotation is prevented by friction coupling means is also mounted rotatably on the support pin. Interposed between the driven member and the main body are one-way engagement means for coupling the driven member to the main body for rotation only when the operating lever is rotated in the direction of return of the derailer spring. These one-way engagement means are controlled directly by the same operating lever, which is constituted by an element separate from the main body and articulated to this body.
