A adjusting device includes arms extending out of the brake assembly and each arm having an abutting surface formed on a free end of the arm and a threaded hole defined in the abutting surface. Threaded bolts each has a spherical head and a threaded rod extending out of the spherical head to be threadingly inserted into a corresponding one of the threaded holes of the arms after passing through a corresponding one of the holes of the connector. A connector is adapted to be formed on an outer periphery of the bicycle frame and having holes so configured that after the spherical head of each of the threaded bolts and the abutting surface of the arms are respectively and oppositely received in the holes, position of the brake assembly is adjustable before firmly connecting the brake assembly to the bicycle frame via the threaded bolts.
