Pedal link for bicycles composed of a central hub of lightweight alloy or equivalent material, to which are connected through openings the pedal supporting link and the sprocket shaft. The link has a threaded extension which is secured ultimately by a nut and the shaft has a terminal, normal opening to allow passage therethrough of the threaded extension of the link. Bevelled surfaces on the link and in the shaft's opening ensure precision fitting of the pedal link components. |
