  • Patent number: 4930843
    Abstract: A bicycle wheel is disclosed having no more than five airfoil shaped spokes linking a central hub to a peripheral rim in a blown and hollow fiber reinforced construction with resulting improvements of wheel spoke windage, overall wheel weight and rim inertia. The bicycle wheel includes a central hub and preferably three or four radially extending spokes. The radially extending spokes all have airfoil shapes. Adjacent spokes extend from the central hub and with the central hub form a spoke arch with each spoke forming one end of the spoke arch and the hub forming a central portion of the spoke arch. The distal ends of this spoke arch form the base support points for segments of the rim extending between the spokes. The segments of the rim extending between the spokes form an opposed rim arch to the spoke arch between the spoke ends.
