bridgtown cona testa tri team - proudly finishing at the back
most disturbing in lycra award, 2010, 2012, 2013
I'd be more worried about looking like an idiot.....with an aero helmet and still really slow.
The greatest trick the devil ever pulled was to convice the world that triathlon was easy
As Mark Cote of the MIT cycling team put it, “Most people don't realize that a nonaero helmet creates four times the drag of a nonaero wheelset. So you can spend two thousand dollars on a wheelset, or spend two hundred on a helmet and be faster.”
If you can stay down and stay aero then get one - you'll get a benefit from it. And if you're compfortable.
