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.
