A roller chain sprocket includes a number of sprocket teeth each having an engaging flank and a disengaging flank. An engaging flank of a first tooth of the sprocket cooperates with a disengaging flank of a second tooth to define a tooth space having a root surface extending between the engaging flank and the disengaging flank. The root surface has a first root surface portion defined by a first radius extending from an arc center of the first root surface portion. A cushion ring is mounted to a first face of the sprocket and has a number of alternating compression pads and grooves. A first groove has a first groove portion defined by a second radius extending from an arc center of the first groove portion. The arc center of the first groove portion being positioned at least proximate a radial line extending between a center of the sprocket and the arc center of the first root surface portion. A first compression pad having an inclined outer surface defined by a leading edge that is spaced radially inward relative to a trailing edge. The leading edge is also positioned radially inward from the engaging flank of the first tooth, and the trailing edge is positioned radially inward from a disengaging flank of the first tooth.
