1. A cycling airfoil system comprising:
a wheel rim having;
a tire engaging portion; and
an inner periphery having uniform width;
a plurality of spokes positioned around the inner periphery of the wheel rim, and the wheel rim is configured to receive a tire at the tire engaging portion;
a plurality of air foils configured in a series solely around the inner periphery of the wheel rim;
wherein each of the plurality of airfoils comprises a convex aerodynamic shape having a leading edge and a trailing edge;
wherein the plurality of airfoils are angled to force wind past the airfoils while a bicycle on which the wheel rim is mounted is in forward motion.
