Abstract:
A bicycle wheel rim comprising an annular rim body with a central axis, said rim body having:annular left and right tire retaining walls which are spaced apart from each other, each of said tire retaining walls having a radial inner edge proximate to the central axis of said rim body, and a radial outer edge distal to the central axis of said rim body, each of said tire retaining walls further having an intermediate portion between said radial inner edge and said radial outer edge; an annular spoke mounting wall interconnecting said radial inner edges of said tire retaining walls and formed with a set of spoke mounting holes adapted for retaining spoke fasteners therein; and an annular connecting wall disposed around said spoke mounting wall and extending between said intermediate portions of said tire retaining walls, said connecting wall cooperating with said tire retaining walls to define a tire retaining cavity that opens in a radial outward direction, said connecting wall having a pair of lateral sections formed adjacent to said tire retaining walls, and an intermediate section formed between and interconnecting said lateral sections, said intermediate section projecting radially and outwardly relative to said lateral sections so as to configure said tire retaining cavity to have two opposite lateral cavity parts proximate to said tire retaining walls, respectively, and an intermediate cavity part between said lateral cavity parts, said lateral cavity parts being disposed on opposite sides of said intermediate section of said connecting wall and being deeper than said intermediate cavity part with respect to said radial outer edges of said tire retaining walls.
