Bow

Abstract

A bow having an increased powerstroke allowing for reduced draw weight and increased speed. The bow is provided with a riser and a pair of limbs. A pulley is coupled to one limb and a cam is coupled to the other at a first journal point and second journal point respectively. The powerstroke is increased by locating the bowstring on the pulley and cam between the riser and the journal points.
