ABSTRACT:
A brake control device for a bicycle is disclosed having main and auxiliary levers which are pivoted to a bracket fixed to the handle bar of a bicycle. The levers are mounted to be swingable independently of one another to swingingly move a wire hook which is integral with the auxiliary lever and which anchors one end of a brake control wire. The main lever is provided with an engaging member for swinging the wire hook upon main lever operation and between the engaging member and wire is provided an adjusting bolt for adjusting the relative position of the wire hook and engaging member. Adjustment of the adjusting bolt controls the distance between the grip portion of the auxiliary lever and the portion of the handle bar opposite thereto. An adjustment of the distance between the main lever and the portion of the handle bar opposite it can also be effected through the provision of an adjustable ratchet mechanism provided in association with the main lever.
