Abstract: A spoked bicycle wheel is presented having at least one intraspoke zone with a reduced average wall thickness to reduce or eliminate the dynamic imbalance of the wheel resulting from localized mass increases at the valve and at a possible joint.

Abstract: A spoked bicycle wheel is presented where the masses of a set of spoke connections for connection of a hub and a rim as a whole are imbalanced with respect to the rotational axis. In such a way the dynamic imbalance of the wheel due to localized mass increases at the valve and at a possible joint is reduced or eliminated.

Abstract: A bicycle wheel, comprising a hub, a rim, and a plurality of spokes extending between the hub and the rim is provided. Each spoke comprises a first end portion coupled with the hub and a second end portion coupled with the rim. The first end portion comprises an abutment surface in contact with a first stop surface of the hub in a tensioning condition of the spoke. A surface substantially opposite the aforementioned abutment surface, on the other hand, does not make contact with the hub. The wheel further comprises locking means of the spoke with respect to the hub adapted to prevent or to limit a displacement of the abutment surface away from the first stop surface in a detensioning condition of the spoke, as in, for example, that which occurs for a violent impact against uneven or rough ground.

Abstract: A hub for a bicycle wheel, comprises a substantially tubular body having, at the opposite free end portions thereof, a plurality of spoke attachment elements projecting radially from the body and provided with seats for housing the spokes of the bicycle wheel is provided. The seats are formed on at least one front surface of the spoke attachment elements. The mounting of the spokes in a hub having such seats is simpler and quicker than in conventional hubs.

Abstract: A rim for a spoked bicycle wheel is disclosed that has a change of radial section of the side walls. Through changes of symmetry/asymmetry with respect to a middle plane and/or changes of radial extent, it is possible to improve the performance of the rim in terms of balance, camber angles and/or strength. Preferably, the radial section is variable, still of constant area along the circumference, apart from apertures for the attachment of spokes and possible openings for the passage of nipples. A process for manufacturing a rim for a bicycle wheel is also described, comprising hydroforming a tubular extruded piece to locally change the section of the side walls.

Abstract: A rim for a spoked bicycle wheel is disclosed, comprising spoke attachment areas and infra-spoke areas, wherein the radial section of the rim in a central part of the infra-spoke areas has a greater moment of inertia than the radial section of the rim in lateral parts of the infra-spoke areas. It is thus possible to increase the stiffness of the rim to counteract the daisy effect.

Abstract: An element for the attachment of a spoke in a bicycle wheel at a seat hole has a body, an axial hole, and can engage a tool. The body is of greater transverse size than a seat hole, and abuts the seat hole at a first end of the body. The axial hole extends from the first end in the body and engages a spoke. The element engages a tool at a second end of the body opposite the first end. Finally, the maximum transverse size of said body is defined by side surface portions of said body other than the area of the second end that engages the tool.
