摘要： A bicycle sprocket includes a sprocket body and a plurality of sprocket teeth. The sprocket teeth extend radially outwardly from an outer periphery of the sprocket body. The sprocket body 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. 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. At least one of the second and third layered members has at least one concavo-convex portion.
