helmet
Lightning Joe I strongly disapprove of your advice. I understand where you are coming from but do you really think it is a good message to spread to cyclists?
I mountain bike so I've fallen hundreds of times over the course of ten years, and I can't even begin to imagine all of the ways that this little melon of mine could get split. I'm sure you know how easy it really is, and if you don't ask any emergency doc and they will tell you. I have also never hit my head but I strap on my sexy ass helmet every time because I don't think you are ever "past" hitting your head. Wouter Weylandt would probably agree if he were alive.
Mine is a 200 dollar GIRO so maybe you have to splurge to get past the slight mass and peripheral vision issues but it's worth it! Everyone wear a helmet!!
