Abstract: A bicycle sprocket includes a sprocket body, and a plurality of sprocket teeth. At least one of the sprocket teeth includes a first layered member, a second layered member and a third layered member. The first layered member has a first axial surface and a second axial surface. The second layered member is attached to the first axial surface such that the first and second layered members overlap each other in an axial direction as viewed parallel to a rotational axis of the sprocket body. The third layered member is attached to the second axial surface such that the first and third layered members overlap each other in the axial direction as viewed parallel to the rotational axis of the sprocket body. The first layered member has a specific gravity that is less than those of the second layered member and the third layered member.

Abstract: A composite bicycle component comprises a first member, a second member, a bonding member, and an inner holding member. The first member is made of metallic material. The second member is made of non-metallic material. The first and second members are configured to form an interior cavity therebetween in a state where the first and second members are attached to each other. The bonding member is configured to attach the first and second members to each other. The inner holding member is configured to be disposed within the interior cavity so as to prevent the first and second members from being separated from each other until completion of attaching the first and second members to each other.
