In this dual control of bicycle brakes the main or racing lever and the auxiliary or sports lever are rigidly interconnected through a common fulcrum pin. The main lever and the auxiliary lever each comprise, in the portion connected to the brake lever fulcrum bracket, a polygonal hole or eye adapted to receive therethrough a fulcrum pin having a matching cross-sectional polygonal contour, so that the levers and pin are rotatably rigid with one another, rings also formed with a corresponding polygonal hole being adapted to be fitted on the fulcrum pin and having a cylindrical outer peripheral contour such that the fulcrum pin is pivotally mounted therethrough in a bearing provided to this end in the brake lever fulcrum bracket.
