1. A crossbow comprising a stock situated at a medial plane of the crossbow and having a proximal end and a distal end, a recurve bow mounted at a distal end of the stock, the bow including pair of spring limbs disposed one at each side of the stock;

  • wherein a bowstring is anchored at each end to an anchor point on each of the respective limbs and is adapted to accelerate a projectile when released from a full brace position;

    at least one strut member extending to right and left sides of the stock and having mounted thereon left and right distal re-directing wheels positioned proximally of the bow and having also mounted thereon left and right proximal re-directing wheels positioned proximally of the aforementioned distal re-directing wheels and distally of the proximal end of the stock;

    wherein the distal re-directing wheels are adapted to contact the bowstring between a partial draw and full release position of the crossbow, and the proximal re-directing wheels are adapted to contact the bowstring between a partial draw and full brace position, so that the bowstring achieves an increased transfer of kinetic energy to the projectile.
