Abstract
An archery bow is provided including a riser and cams configured to maintain alignment of the cams to decrease lateral or horizontal nock travel, and thereby increase overall accuracy. The riser can include a lower portion having a leg that flexes so that a lower cam of the bow moves laterally in a direction less than or equal to the amount an upper cam moves in the direction. The upper and lower cams can be sized differently, for example, with the upper cam including a longer bowstring payout track than the lower cam, to ensure consistent and appropriate nock travel. The riser and cams can facilitate placement of a center grip at the geometric center of the riser or between the limbs/cams. With such placement, the nocking point can be located above this geometric center. This can enhance the balance and feel of the bow. Related methods are also provided.
