Abstract
A bicycle gearshift comprising first and second moveable bodies, a rocker arm rotatably connected to the second body on a rotation axis, an elastic element that rotates the rocker arm about the rotation axis, and a unidirectional damping device operatively arranged between the rocker arm and the second body. The unidirectional damping device comprises a first ring nut arranged coaxially to the rotation axis and rotatable with the rocker arm and a second coaxially arranged positioned axially adjacent to the first ring nut. The first and second ring nuts have matching saw-toothings. An actuator for the unidirectional damping device acts on one of said ring nuts to axially push that ring nut towards the other ring nut so as to mutually engage the saw-toothings when the rocker arm is moved about the rotation axis in a second direction of rotation. A first friction surface is associated with the second ring nut and a second friction surface is associated with the second body and is configured to slide on the first friction surface when the rocker arm is moved around the rotation axis the second direction of rotation.
