Abstract

An archery bow system incorporating a bow riser and dual limbs supporting cams or a cam and wheel mounted for rotation about respective axles. The dual limbs are independently adjustable to correct for cam lean and are individually supported in pockets that incorporate variable limb angle attachments to the bow riser. The limbs extend from the riser to flex, when at full draw, to positions that cause the respective axles to initially travel rearward toward the archer upon release of the bowstring. The limbs are adjustably attached to the riser to permit the limb angle with respect to the riser to be changed.

Claims (5)

1. In an archery bow having:

(a) a riser having first and second ends;

(b) a pair of flexible limbs secured to said first and second ends, respectively, each having a pivot axis about which the respective limb flexes; and

(c) an axle secured to each of said flexible limbs and a cam or wheel mounted on each axle, the improvement comprising:

a limb riser ratio of substantially 0.22 or less wherein said ratio is defined by the length of the limb measured from a limb pivot to an axle divided by the length of the riser measured from a limb pivot axis of a first limb to a limb pivot axis of a second limb.
