description 1. Field of the Invention A bicycle wheel rim has an integrally formed annular rim body with left and right tire retaining walls, and a base wall interconnecting the tire retaining walls. The base wall has a radial inner face facing a central axis of the rim body, a radial outer face, a left section connected to the left tire retaining wall, a right section connected to the right tire retaining wall, and a vaulted portion interconnecting the left and right sections. The vaulted portion is vaulted in a radial outward direction relative to the left and right sections so as to define an annular recess in the radial inner face and an annular protrusion on the radial outer face. The annular recess is adapted for retaining a peripheral portion of a circular disc therein. Optionally, the base wall is formed with a plurality of spoke mounting holes distributed in the left and right sections and adapted for retaining spoke fasteners therein.
