OK, this is a bit off-topic, but there are a few racers here, and I found this very interesting, and a little disturbing... CAMS is talking about introducing the snell standard for helmets. This article (and test) is a loooong read, but very interesting. Seems that rather than the old "$50 helmet for a $50 head" adage being true, it's actually more a case of "more dollars then sense"
