Abstract: A metal spoke for a cycle wheel having a tapered body and two ends respectively for the fastening to a hub and a rim. The tapered portion of the spoke is smooth and exempt from threading over its entire length; the spoke has at each of its ends an enlarged head; and a recessed fastening screw is mounted in free rotation between the two enlarged heads. The spoke is made from a light alloy shaped in the annealed state, then heat treated by tempering. The invention also relates to a wheel having a rim, a hub and spokes.

Abstract: An inflation valve provided to inflate a cycle tire assembled without an air tube on a rim. The valve has a body crossed by a conduit, with a first part being designed to cross the casing of the rim, and a second part adapted to connect an inflating means. The valve has an injection nozzle located in the extension of the first part, a sealing joint located around the injection nozzle, and in that the first part or nozzle has an assembly device designed to cooperate with the complementary assembly device of the rim.

Abstract: A display device provided to be associated, on the one hand, with an electric gearshift, and, on the other hand, with at least one sensor of at least one performance parameter of the bicycle or the cyclist. The gearshift is provided to emit a confirmation signal that a requested displacement did occur. This signal is sent to a processing circuit which elaborates information relative to the sprocket called, then sends this information to a display manager. During a period predetermined by a time delay, the display manager blackouts one of the current displays from the display unit and sends the information relative to the sprocket called to the display.

Abstract: A quick-locking pin including a longitudinal rod, a first tightening stop at one end of the rod and a second tightening stop at the second end of the rod. The second tightening stop includes a second tightening ring, a lever mounted and journalled at the second end of the rod beyond the second tightening ring, the lever having a tightening cam off-centered with respect to its axis of rotation. The axle of the lever is borne by a cap located at the end of the rod between two arms. A transversely movable beam located between the arms of the cap is situated between the periphery of the cam and the external surface of the second tightening ring.

Abstract: A rim for cycle wheel, provided to receive a tire and having in transverse cross-section two lateral wings forming the two lateral sides of the rim. The two lateral sides are joined at their base by a lower bridge and in their median portion by an upper bridge, so as to produce towards the tip of the wings an annular groove for receiving the tire. The rim has a rectangular global shape in cross-section. The lower bridge has a thickness less than about 0.7 millimeters.

Abstract: Free wheel hub for cycles, in which the wheel hub is driven by the free wheel, by means of a unidirectional connection constituted by the cooperation of at least one movable ratchet acted upon by a spring so as to move toward an operative projecting position, in which it cooperates with teeth, this ratchet being free to pivot on a support piece fastened to the hub body, while the teeth are produced on a free wheel body. The ratchet-support piece is made of a material whose mechanical properties and/or density are similar to those of the material used to make the hub body, this ratchet being mounted so as to pivot on a gauge rod attached to the support piece, this gauge rod being made of a material whose mechanical properties and/or density are similar to those of the material used to manufacture the free wheel body.
