Abstract
A compound bow comprising a handle portion having a first limb and a second limb extending outwardly therefrom, a wide body cam assembly pivotally coupled to the first limb near an outer end thereof, and a dual wheel assembly pivotally coupled to the second limb near an outer end thereof. The wide body cam assembly comprises a main sheave and a collector sheave located on opposite sides of a cable sheave. The main sheave is spaced apart from the cable sheave by a first distance sufficient to permit arrows to be fired from the bow free from interference by a cable without the use of a cable guard. The dual wheel assembly comprises a feed out sheave and a take in sheave separated by a second distance which is larger than the first distance. The feed out sheave is positioned substantially within a plane defined by the main sheave.
