A power transmission chain and sprocket drive comprising a toothed sprocket and a chain composed of a plurality of sets of links with pivot means joining successive sets of links to permit articulation of one set of links relative to an adjacent set of links, each of said links being defined by a pair of spaced toes each formed by a pair of diverging flanks, each pair of diverging flanks comprising an outside flank and an inside flank, the inside flanks of the toes of each link being joined by a crotch, the improvement comprising that each inside flank is defined by a curve of a predetermined radius with the center of said curve for some sets of links being located differently than that for other sets of links, each link in each set drivingly contacting said sprocket teeth only with their inside flanks whereby the time interval of driving contact with said sprocket teeth for some sets of links is different than that of other sets of links.
