Abstract
A bicycle sprocket has a rotational center axis. The bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, and at least one chain-supporting portion. The plurality of sprocket teeth are circumferentially arranged on an outer periphery of the sprocket body. The at least one chain-supporting portion is configured to contact one of inner link plates of a bicycle chain without engaging with the bicycle chain at inner link spaces each defined between a pair of inner link plates that face each other in an axial direction parallel to the rotational center axis. The at least one chain-supporting portion is offset from the sprocket teeth in the axial direction.
