Cam Adjustment Mechanism for Compound Bow

摘要

A cam adjustment mechanism is provided for both single and dual cam bows which enables excess cable length to be removed to re-sync the cams to restore performance of a bow which has experienced degradation due to unequal cable elongation. The cam adjustment mechanism can also be used to tune the bow to the archer's preferred characteristics.
