Helmet position for time trialists

Joe Friel has an interesting article about the optimization of aerodynamics for time trialists. He has been testing different setups of head position (aero helmet, head position, etc.) and saved 77 seconds. I can strongly recommend time trialists to have a closer look at that article and notice Joe Friel’s final comments: “I’m afraid many helmets on the market that are marketed as “aerodynamic” are actually less aerodynamic than a standard road helmet. And even wearing a decent helmet with the front down close to the eyebrows, while it may look good, is actually slower than with the helmet’s leading-edge worn closer to the hairline in front.”
