A chain ring for engaging a chain link of a chain, the chain ring including an inner edge fully circumscribing both an opening and an axis of rotation, an inner surface extending between the inner edge and an outer edge where a plurality of chain ring teeth emanate, and a plurality of ramps disposed about the inner surface, wherein at least one of the plurality of ramps includes a lifting surface for initiating lift of a chain without assistance from the plurality of chain ring teeth. The lifting surface extends radially along the inner surface toward the outer edge, and the at least one ramp has a first end proximate the inner edge and a second end proximate the outer edge. The second end of the at least one lifting surface terminates before reaching the bottom of a trough positioned between two or more of the plurality of chain ring teeth.
