A bicycle gearshift including a first body associated with a bicycle frame, a second body connected to, and moveable relative to, the first body, a rocker arm rotatably connected to the second body at a rotation axis, and a shaft extending coaxially to this axis and fixedly associated with the rocker arm. A unidirectional rotation device is arranged between the shaft and second body to allow rotation of the shaft relative to the second body only in a first rotation direction. An elastic element is associated with the second body and the rocker arm to push the rocker arm in rotation about the axis in the first rotation direction. A damping device is arranged between the shaft and unidirectional rotation device to generate a friction force when the rocker arm is rotated in a second, opposite rotation direction, and has a friction surface in contact with the unidirectional rotation device.
