Abstract
A bicycle wheel rim includes a unitary integrally formed rim body which has annular left and right tire retaining walls that are spaced apart from each other, and an annular bridging portion. Each of the tire retaining walls has a radial inner section proximate to a central point of the wheel rim, a radial outer section distal to the central point of the wheel rim, and an intermediate section between the radial inner and radial outer sections. The radial outer sections of the tire retaining walls are adapted for retaining a bicycle tire therebetween. The bridging portion interconnects the intermediate sections of the tire retaining walls, and cooperates with the tire retaining walls to provide the rim body with a generally H-shaped cross-section.
