摘要： A bicycle rim is basically provided with an annular metallic rim member and a reinforcing member. The annular metallic rim member includes a plurality of spoke attachment areas with at least one spoke attachment opening in each of the spoke attachment areas. The reinforcing member overlies an exterior surface of the annular metallic rim member. The reinforcing member includes a plurality of spoke attachment sections individually arranged in a circumferential direction to overlie the spoke attachment openings. The spoke attachment sections include a plurality of discrete first reinforcing parts and a plurality of discrete second reinforcing parts. The first reinforcing parts are attached to the spoke attachment areas around the spoke attachment openings. The second reinforcing parts are attached to the spoke attachment areas to overlie the first reinforcing parts, with the second reinforcing parts being larger than the first reinforcing parts.
