Abstract

A crossbow may include a main beam; a compound bow assembly mounted to the main beam; and, a trigger mechanism mounted to the main beam for use in holding a bowstring in a cocked position. The crossbow may include wheels at opposite ends of the bow that operatively receive the bowstring. The wheels may be separated by a wheel distance (WD) when the crossbow is in an un-cocked position. The crossbow may also have a power stroke distance (PD) and the ratio WD/PD may be less than 2.0.
