ABSTRACT:
A bicycle wheel rim includes an annular frame formed from a metal strip with opposite end portions and having spaced left and right annular tire retaining walls with brake pad contacting surfaces, an annular inner spoke mounting wall interconnecting inner edges of the tire retaining walls, and an annular outer connecting wall disposed around the spoke mounting wall and interconnecting the tire retaining walls. The tire retaining walls, the spoke mounting wall and the outer connecting wall cooperatively confine an annular channel. Each of the left and right annular tire retaining walls, the spoke mounting wall and the outer connecting wall has two confronting end faces that are disposed respectively at the end portions of the metal strip and that are in close contact with each other. A connecting member is fitted in the channel and extends into the end portions of the metal strip. A weld connection is provided on the annular frame to strengthen connection between the end portions of the metal strip. The brake pad contacting surfaces of the tire retaining walls are free of any weld flash.
