A belt construction having opposed inner and outer surfaces with each surface defining a plurality of longitudinally disposed and alternately spaced apart like projections and grooves that are adapted to mesh with a ribbed surface of a pulley, the depth of the grooves of each of the surfaces of the belt construction being substantially less than the approximately 2.4 mm depth of the grooves of a similar belt construction that is adapted to have one of the opposed surfaces thereof mesh with the ribbed surface of the pulley in the same manner as the first mentioned belt construction, the belt construction having a tension section comprising a cushion section and cord member, the cushion section being initially disposed on only one side of the cord member with the cord member thereafter being embedded therein.
