A force compensation device is provided in a cable control for at least one chain derailleur secured to a bicycle frame for operating a chain ring or a chain gear. The control cable is secured at a first end to the derailleur and at a second end to a control member that may be a lever, a handle or rotating grip. The derailleur includes a return spring returning to a compressed state when the chain is on the largest chain ring or gear. The control member includes at least one counter-acting elastic restoring element that is in the relaxed state when the return spring of the derailleur is in the compressed state. The counter-acting elastic restoring element is disposed between a fixed stop secured to the bicycle frame and a fixed stop secured to the second end of the cable.
