You know what it's about: money & all the rest of that crap! (racisim, opportunity, education, culture, etc)
I wear a $30 helmet, made by Bell and sold at Walmart. It is a good as any helmet at any price. Any helmet that can legally be sold in America is good enough to prevent a TBI (Traumatic Brain Injury) from the great majority of falls.
I know what I'm talking about ;o)
