ABSTRACT:
A speed-changing device for a bicycle, comprising a derailleur, a control lever and a transmitting device formed of an outer cable and a less flexible inner wire. One end of the outer cable is fixed to the derailleur and the other end is fixed to the control lever. The lever is reciprocally operable to push or pull the inner wire for allowing a movable member of the derailleur to be reciprocated, whereby a single wire can, without a return spring, lightly effect the bicycle's speed change.
