Great question, I don’t have an answer however. I bet the answer relates to my post on aerodynamic helmets. I have noticed that when I am drafting in a peloton and tucked down my visor is a bit of a problem. Perhaps that is changing the way you hold your head and causing the helmet to dig in.

But like I said I am not sure. Very interested in what other will say about this. Hope there are folks out there smarter than me with all the answers!
