Yes, a nose strake at an angle to the ground was used on road racers such as the Lola T-70. As to the cross section, an aircraft or glider fuselage may have circular or elliptical shaped bulkheads. I am working on egg shaped bulkheads with the smaller end toward the ground. The overall shape of the body is based on a glider design shorted to a 3:1 ratio. (The SZD-9 bis Bocian 1E, nose to bulkhead #6). The bicycle builders at Specialized have settled on a design for their aero frame tubing as a truncated 5:1 shape that is also low drag in 15 degree cross winds.
