Abstract: 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 openings of the annular rim have reinforcement members or washers located between the spokes and annular rim. The outer ends of the spokes have bent sections located within the spoke holes of the reinforcement members or washers and head section that engage the inner surface of the reinforcement members or washers. The rim is provided with a reinforcing rib or bend above each of the spoke holes. The reinforcing rib or bend can be continuous or discontinuous. The spoke attachment portions of the rim are divided into an outer circumferential section, a middle circumferential section with the spoke openings formed therein and an inner circumferential section. At least parts of the middle circumferential sections of the spoke attachment portions have a first predetermined wall thickness located above and below the spoke openings. The first predetermined wall thicknesses of these parts are greater than a second predetermined wall thickness of the inner circumferential sections of the spoke attachment portions.

Abstract: 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.

Abstract: 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.
