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.

Abstract: A reinforced booster for a bicycle brake is substantially U-shaped and attached to the pivot points of the bicycle brake to increase its braking power. The reinforced booster has a substantially U-shaped member with inner and outer peripheral edges which have high strength strands of fiber attached thereto for increasing the strength of the U-shaped member. The strands of fibers extend longitudinally along the peripheral edges of the U-shaped member. Preferably, the U-shaped member is constructed of a plurality of sheets of a non-metallic material. For example, a plurality of carbon sheets can be used to form the U-shaped member. The strands of fibers attached to the peripheral edges of the U-shaped member can be, for example, carbon fibers, polyamide fibers, glass fibers or other reinforced plastic fibers. The free ends of the booster has mounting holes which are preferably formed by strands of fibers.
