Abstract

The invention concerns a gear-shift device (1) for a cycle (2) with chain (5) sprocket and chainwheel (4a) transmission, said device consisting of a control element for actuating a mobile gear-shift member (8) which co-operates with the transmission chain (5) to shift it from one sprocket wheel or chainwheel (4a) to another sprocket wheel or chainwheel (4a). The invention is characterised in that the mobile gear-shifting member is pivotably mobile about a pivot pin.
