ABSTRACT:
The present invention refers to improvements in a free-wheeling mechanism for bicycles of the kind including two fixed cones and one movable cone, mounted on an axle and so constituted as partially to provide races in which balls run; furthermore, the movable cone includes at one of its end portions a slotted head in which there rest rollers which are guided by a suitable device, which is also connected to the axle; and there is a hub in which the foregoing parts are housed with the exception of the end of the movable cone opposite the end having the slotted head; the improvements are holding means of the guide device which enable same to force the rollers into contact with the hub or prevent their contact therewith, depending on whether the wheel is to run under engagement or to turn freely without pedalling.
