Clipped a mirror on a parked truck trying not to bump a group rider , did a flip landed on my ARS, and must have hit my head (I don't remember hitting the ground). I put my bike back on the road and survyed the damage, My head didn't hurt but my back side was stinging. So I decided to head home, I then had 48 hours of explicit pain in my hips, and my groin muscles. I checked my bike closely the next day, its fine except for the air pump mount was broken off.
I then went over my clothes no rips or tears. whew 100 buck riding pants with the scorpion design.
And finally my helmet, as I looked it over it was intact except for a major split in the foam the entire center section was spit in two. I decided the helmet was a good idea in the future, its was a freak accident but that seems to happen alot lately..
I bought a new helmet this time the Atas a bigger helmet my LBS reccomended for my fat head.
You can say helmets cramp your style, but I believe mine saved my head.
