Abstract
A draw length adjustment system including a draw stop, an adjustment element and a fastener that joins the draw stop and/or adjustment element with a cam or pulley of an archery bow. The draw length adjustment system is micro-adjustable so that an archer can make minute and/or incremental adjustments to the draw stop, and thus the draw length of the archery bow. The draw stop can be of an eccentric construction that is eccentrically rotatable relative to the cam or pulley to alter the draw length. Alternatively, the draw stop can be selectively moveable relative to the cam assembly via a rack and pinion gear to alter the draw length.
