Generally I don't wear a helmet when I ride. There I've said it. In the winter I do for warmth and in case I hit a patch of ice, but rarely in the summer. (Feel free to chastise me as you see fit)
However as I train for my first tri I know I will need to wear one. I also know I should probably get used to it before the event also.
Does anyone know which helmet is the smallest, lightest, least obtrusive, lowest profile (ok I think I've made my point) helmet that is still within the legal standards? I figure if I get something like that and get used to wearing it, it will be like a seatbelt- more of an automatic thing. Thanks.
