    If you do it, make sure you do a better job than Bozic.

    Certainly, but you may make it less aerodynamic rather than more. Aero helmets are wind tunnel tested and aerodynamics is a funny old business. Just covering your helmet with clingfilm may create an area of low pressure behind it if it has a high back and that would increase drag.

    How much faster do you think you will go covering them?

    A friend of mine who is now chief of aerodynamics at BC did this - bought a cheap helmet from halfords and carefully cling filmed it. He really believes in small aero improvements such as helmet, shoe covers, wheels etc. They all add up.

    If he believed in small aero improvements surely he would get a proper aero helmet?

    Is would assume the cheap helmet and clingfilm was to test the theory rather than to use instead of a proper aero helmet.

    Would be interesting to know if anyone has quantified the benefits of these small things as as an amateur, you could make the best choice based on what you can afford. Like a post above said - you could make things worse.

    Added benefit: avoid wasps entering your helmet and stinging you on the head!

    Winning is winning, whether its by an inch or a mile ;)

    Sometimes its the tiny little things that clinch an event :D
