A bicycle brake cable system has a brake cable coupling arrangement in which a plurality of branches are provided from a single brake lever force application lug. Splitting of the brake cable is performed within the structure of a brake barrel adjuster. The barrel adjuster is provided with a cylindrical cavity that receives a rotatable coupler therewithin. The interface ends of the force transmission cable segments are terminated in the coupler, which is free to rotate relative to the barrel adjuster. As a consequence, the barrel adjuster may be threadably advanced to either increase or decrease brake tension by rotation relative to its threaded connection to the brake lever assembly body. By providing a coupler that is rotatable relative to the barrel adjuster, the barrel adjuster can be rotated in both directions to increase or reduce brake tension. The relative rotation between the coupler and the threaded nipple of the barrel adjuster allows the force transmission segments of the brake cable to remain stationary relative to the handlebars, while still permitting tension adjustment on the brake cable.

[ I claim:] [1.] In a bicycle brake cable having a brake lever force application lug, a cable segment connector having opposing force application and force transmission ends and a common axis of alignment extending therebetween, and a plurality of force transmission segments, each having a central, flexible, inextensible core element and a surrounding sheath element within which said core element is movable in longitudinally reciprocal fashion, joined to said brake lever force application lug at said cable segment connector, the improvement wherein said cable segment connector is located adjacent to said brake lever force application lug and further comprising a coupler mounted in said cable segment connector so that said coupler and said cable segment connector are freely rotatable relative to each other about said common axis of alignment and said sheath elements of said plurality of force transmission segments are seated in said coupler at a fixed axial distance along said common axis of alignment between said force application end and said force transmission end of said cable segment connector, and said force transmission segments are rotatable relative to said cable segment connector together with said coupler and said core elements of said plurality of force transmission segments are all connected to said force application lug at said cable segment connector.
