Apparatus for the control by a cable of a speed change device comprising an articulated parallelogram including a fixed upper support, a laterally movable lower support and two parallel levers pivotably connected to the supports. A chain guide is secured to the lower support and is laterally movable therewith for derailing a chain on pinions of a free wheel cluster. The parallelogram is subject to an elastic member which deforms the parallelogram in one direction, the cable acting on the parallelogram to deform it in the other direction against the action of the elastic member. The sheath of the cable is secured to the upper support of the parallelogram and the cable itself is secured to the lower support of the parallelogram such that application of external force to the cable produces deformation of the parallelogram. The upper support has a projection which can be integral therewith or attached thereto for carrying the sheath stop and disposing the same in an offset position laterally in the direction of the free wheel cluster and vertically in the direction of the lower support. The projection can have a groove in which the cable is received.
Apparatus for the control by a cable of a speed change device comprising an articulated parallelogram including a fixed upper support, a laterally movable lower support, two parallel levers pivotably connected to said support, a chain guide secured to said lower support and laterally movable therewith for derailing a chain on pinions of a free wheel cluster, elastic means acting on the parallelogram to deform the same in one direction, the cable acting on the parallelogram to deform the same in the other direction against the action of the elastic means, means securing said cable to said parallelogram at first and second spaced locations such that application of external force to said cable produces deformation of said parallelogram, and projection means on said parallelogram, carrying said means for securing said cable at said first location, said projection means offsetting said first location both laterally in the direction of the free wheel cluster and vertically in the direction of the lower support to reduce the angle of the cable connected at said first and second locations with respect to the direction of lateral movement of the chain guide.
