Abstract
An eccentric for a compound bow includes two sheaves for the bowstring and tension runs, respectively. The sheaves carry nonparallel tracks of noncircular configuration which are oriented so that the cam ratio of the eccentric increases rapidly during the initial stages of draw. The track for the tension run includes a ramp which urges the terminal end of the tension run down towards the axis of the eccentric and away from the plane of the bowstring.
