ABSTRACT:
A bicycle control device comprises a brake lever for attachment to a brake operating cable, a clamp member for attachment to a handlebar of the bicycle, and a lever bracket for pivotably supporting the brake lever. The lever bracket is supported by the clamp member for rotation about an axis of the handlebar. A winding member is mounted between the lever bracket and the clamp member. The winding member is capable of rotation about the axis of the handlebar for alternately winding and unwinding a transmission cable. A clutch for transferring rotational motion of the support member to the winding member so that rotation of the lever bracket from a first position to a second position causes the winding member to rotate from a corresponding first winding position to a second winding position.
