Joe Friel has an interesting article about optimization of aerodynamics for time trialists. He has been doing some testing with differents setups of head position (aero helmet, head position etc.) and saved 77seconds. 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.”
I found this link via PowerTap Geek that publishes a lot of interesting articles for PowerTap freaks.
