A power transmission chain having a plurality of pin connected articulating arid guide ranks wherein each rank may include plain links having a thickness that may vary from rank to rank. A group of plain links having a pre-selected thickness is disposed in articulating ranks through-out the chain. Other groups of plain links having a different preselected thickness axe disposed in nonarticulating ranks of the chain. The combination of different thickness plain links disposed in a preselected manner coupled with elastic guide links throughout the chain is effective to minimize wear. The groups of plain links having preselected but different thicknesses cooperate with different thickness guide links therein so as to improve load distribution thereacross, achieve equal deformation between the plain links and the guide links and maintain the transverse connecting pins substantially parallel to each other. The plain links in this chain which are of the two tae variety are characterized by having nonidentical toes. As a result of this difference, the dimensions from the center of the pins to the working surfaces of each toe vary with the result being that the timing between successive link and sprocket tooth engagements can be varied.
