PROBLEM TO BE SOLVED: To provide brake shoe for a bicycle having braking performance improved in wet conditions, preventing a rim, when decelerated or stopped, from being excessively worn by the brake shoe for a bicycle while maintaining good performance in the wet conditions. SOLUTION: The brake shoe for a bicycle, which has a rim contact portion with a braking face formed out of a non-sulfur crosslinked polymeric compound crosslinked by zinc methacrylate, is provided for solving means, and the brake shoe for a bicycle, which has a rim contact portion with a braking face formed of one polymeric compound selected from the group consisting of a butadiene rubber crosslinked by peroxide and metallic ion crosslinking structure and an acrylonitrile butadiene rubber, is provided for solving means.
