Abstract An endless power transmission belt construction, a rotatable pulley therefor, a combination of the belt construction and pulley and methods of making the same are provided. The belt construction (20) comprises a plurality of longitudinally disposed and alternately spaced apart like V-shaped projections (38) and grooves (39) for meshing with an outer peripheral ribbed surface (40) of a rotatable pulley (41). The projections (38) are defined by two substantially straight side edges (44) which form an angle (A) of approximately 60° therebetween with the thickness (T) of the belt construction (20) being substantially the same as the thickness of a similar belt construction wherein the angle is approximately 40°, and with the distance (P) between the center lines (CL) of those grooves (39) of the belt construction (20) that are on opposite sides of that projection 138) being larger than such distance of the similar belt construction.
