Though I have gone down on black ice and been hit by two cars, the most potentially serious cycling-related head injury I have experienced was, like the story of the woman and the speed bump above, going lest than 10 mph. Long story. But the punch line is, I slammed the right side of my head hard on the pavement. It literally bounced off. DId not lose consciousness, no symptoms. I was fine. But had I not been wearing any helmet of any kind? I shudder to think of that.

That helmet had some little denting in it and, because of how I feel it performed, I replaced it with another just like it. It is a poc Octal. No SPIN, no MIPS, no WaveCel. Just a helmet. But it worked.

I am not a neurosurgeon, but I do have a whole lot of trauma experience. I am pretty sure in an afternoon on the phone, I could find you a small army of neurosurgeons with cases of brain disasters that happened with no helmet on the bike. Staistics are great, but it is the details and the nuances in between those numbers that usually tell the real story.
