[QUOTE=carleton;16399564]I wonder how a $50 Skate helmet ranks among Sprint helmets in aero tests. I wish someone would put them in a wind tunnel./QUOTE]
Wind tunnel won't do much for sprint helmets as the head position changes too much to get "clean" data- too many things moving around.
An ERO setup could probably do it, but roll down/Aerolab/tunnel set ups? Probably not.
that said, a round skate lid might test well-trick it to test it, I come out differently than several teammates who ride similar-ish positions, helmets seem to be the most individual bits of gear.
