A silent chain and sprocket combination includes a silent chain having a plurality of interleaved links (2), each link having a pair of teeth (21), with each tooth having an inner flank (23) and an outer flank (24). The links of the chain engage the sprocket teeth on their inside flanks (23) during initial engagement and full engagement. The sprocket tooth (t) has a flank shape with a first part that matches the lower portion of the shape of the inside flank (23) of the link tooth and a sprocket tooth flank shape with a second part that matches the upper part of the link tooth shape. <IMAGE>
