Abstract: A compound bow includes a pair of improved pivotally mounted cam assemblies having separate, specification profiled string cable segments and power cable segments constructed and arranged to produce a draw force curve representing a greater area of stored energy than that obtained with most existing compound bows. The draw length of the bow, among other parameters, is readily altered without compressing and dismantling the bow cable components by removing and replacing differently configured draw length cam modules associated with the power cable segments. Attachment and subsequent turning of each of the timing, string and power cables is easily accomplished by means of cable adjusters carried by each cam assembly.
