摘要： A bicycle wheel basically has a hub, a plurality of spokes extending outwardly from the hub and an annular rim coupled to the outer ends of the spokes for supporting a tire. The annular rim has a spoke attachment portion with a plurality of openings and radially extending recesses for receiving the outer end portions of the spokes therein. The outer end portions of the spokes are at least partially recessed within the radially extending recesses to provide an aerodynamic design. The outer end portions of the spokes are preferably bent such that first sections of the spokes are offset from sections of the spokes. These bends are positioned in the openings of the rims to retain the outer ends of the spokes in the openings of the rim. In selected embodiments, the offset section between the first and second sections is either thicker or corrugated.

摘要： A bicycle wheel basically has a hub, a plurality of spokes extending outwardly from the hub and an annular rim coupled to the outer ends of the spokes for supporting a tire. The annular rim has a spoke attachment portion with a plurality of openings for receiving the outer ends of the spokes therein. The outer ends of the spokes are bent such that first sections of the spokes are offset from sections of the spokes. These bends are positioned in the openings of the rims to retain the outer ends of the spokes in the openings of the rim. Optionally, an adhesive may be used to more securely retain the outer ends of the spokes in the openings of the rim. In certain embodiments, the spoke attachment portion of the rim can be constructed of individually spaced elements which can be either fastened to the rim or unitary part of the rim.
