Egads..that's a Canadian helmet.
Where is this going to go next?
One major issue with aero helmets is that they only work well in one position, and they make a huge difference. But if you look down, it's like throwing up a sail.
It's really hard to un-learn this, you have to learn not to look at your gearing, and the instinct that head down is faster. Zabriskie does this very well, he locks his head facing forward.
