Abstract: A bicycle handlebar that terminates in two rearwardly extending horizontal ends, these ends terminating forwardly in first upwardly curved portions having a first radius of curvature. These first upwardly curved portions terminate forwardly in forwardly and upwardly inclined rectilinear portions, these rectilinear portions terminating forwardly and upwardly in second upwardly curved portions having a second radius of curvature substantially smaller than the first radius of curvature. These second curved portions in turn terminate in upwardly and rearwardly inclined portions which terminate in a common crosspiece by which the handlebar is adapted to be secured to a stem of a bicycle.

Abstract: A bicycle brake actuating device includes a brake lever (21) hinged in such a way to turn around an axis (X) substantially parallel to the supporting axis (Y) of a cyclist's hand. The brake lever can be supported by two tabs (17) placed on the hand's supporting handle (14). A holding cavity (40) is preferably utilized to receive the transmission of the brake lever and the mechanism (30, 32) that is part of the actuating device.

Abstract: Brake block fastening device for bicycle, made up of a body and a resilient element, which combined together form a cavity capable of receiving and retaining the brake block, the resilient element being kept close to the body by a shifting cam device, capable of selectively locking or unlocking the block.
