A single rear bicycle brake control cable core is employed to operate the rear brake of a freestyle bicycle that employs a rotatable coupling that allows the handlebars, front wheel, and front wheel fork of a bicycle to be rotated through a complete revolution about the axis of the head tube of the bicycle frame. The single brake control cable core is looped about a roller which may be a pulley attached to the cable-engaging end of the handlebar-mounted rear brake lever, so that the point of contact between the control cable loop relative to the brake lever is not fixed. Cable sheaths surround portions of the cable core and are seated in a cable segment connector that in turn is rotatably mounted in a cable coupler attached to a handlebar-mounted brake lever assembly body. The coupler rotates about its own axis to maintain the unsheathed, proximal portions of the loop adjacent the pulley in coplanar alignment with the pulley. The brake lever rotates relative to the brake lever assembly body so as to move the pulley closer to or further from the cable coupler. Because the control cable loop passes about the pulley, tension on the cable brake line allows the gyroscopic system to self-adjust the balance of its bearing unit. Preferably, a toggle link is provided between the cable-engaging end of the brake lever and the cable core loop. The pulley is mounted at the end of the toggle link, remote from the brake lever.
