Abstract

A bicycle chain ring having a plurality of teeth extending radially about an axis of the chain ring, the plurality of teeth including a first group of teeth and a second group of teeth. The first group of teeth has a first width at a tooth base that is sized to be received within a chain cavity defined between parallel links of a bicycle chain. The second group of teeth has a second width at the tooth base, the second width being different from the first width. Further, the first group of teeth have a tooth tip that is substantially centered on a plane defined between an inner surface and an outer surface of the chain ring and the second group of teeth is at least partially offset from the plane.
