I just got done watching the first stage of the Nature Valley Grand Prix (http://www.naturevalleygrandprix.com/). The most popular helmets I saw were 1) Louis Garneau Prologue, 2) Rocket, 3) Rudy. T-Mobile (ladies) all had Uvexs… which I found interesting because I didn’t think they were US legal yet. If racers didn’t have one of these 3 types, they were maybe wearing something retro or a standard helmet.
