An improved link for a chain for use with a sprocket, the link comprising a body having a pair of apertures for receiving connecting pins and a pair of teeth having outside flanks, and inside flanks between the teeth defining a crotch. The improvement includes an effective outer flank angle between a line tangent to the outer flank of the link at 1.5P and a vertical line intersecting the tangent line of less than or equal to 29 degrees, an effective inner flank angle between a line tangent to the inner flank of the link at 0.5P and a vertical line intersecting the tangent line of less than or equal to 29 degrees, and a plurality ratios. The links may be assembled into a chain and connected by a plurality of pins.
