摘要： A bicycle wheel rim for mounting with two tire rim portions of a tire includes an outer ring wall surrounding a rotation axis of the wheel rim, and two annular flanges. Each annular flange has an inclined inner surface for abutting against a respective one of the tire rim portions. The outer ring wall has two retaining surfaces, each extending from the corresponding one of the annular flanges toward the central radial plane of the wheel rim and being inclined radially and outwardly with respect to the rotation axis. Each retaining surface and a corresponding inclined inner surface cooperatively form therebetween an included angle smaller than 90 degrees, and clamp the respective one of the tire rim portions.
