ABSTRACT:
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.
