Abstract
An archery bow comprises a riser and a pair of bow limbs. The riser has a central portion and first and second end portions, each including a corresponding forward pivotable connection point and rearward bearing point substantially rigidly positioned on the corresponding end portion. A bearing member is positioned at each corresponding rearward bearing point. Each bow limb has a riser connection point and a pulley connection point, and is (i) pivotably connected at its riser connection point to the corresponding riser end portion at its pivotable connection point, (ii) positioned against the corresponding bearing member at a point along the bow limb between its riser and pulley connection points that is displaced from the riser connection point by at least one third of the distance between the riser and pulley connection points, and (iii) arranged at its pulley connection point to receive a pulley member pivotably connected thereto.
