A tension-type belt/pulley system provides an improved concept for retaining the bands of the drive belt within the pulley cones while increasing the maximum operating pitch radius of the belt for a given pulley radius, thereby increasing the ratio range of the system. The pulley flanges are chamfered at their outer ends to provide smooth re-entry of the bands into the cones in the event the bands drift laterally during a half revolution of the belt.
