ABSTRACT:
The bow has a first arm and a second arm, the first arm flexing more than the second arm during drawing movements of the bow, and a pulley on at least one of the arms. A bowstring with a nocking point extends between the arms. The pulley and the bowstring are arranged on the bow so as to maintain the nocking point in substantially the same plane as the arrow shelf in all drawing movements of the bowstring.
