Maybe its not you, but the bike. I had some tough times on my old SS bike. I crashed probably around 15-20 times on it in less than a year, and those crashes resulted in a concussion, broken wrist, ****ed up shoulder, busted knee, and a broken ankle, and lots of painful oozy road rash.
I was feeling like I had it with that bike, so I got rid of it. To get rid of the bike and also to get rid symbolicly (sp?) of my troubles on my bike, I just thew the whole bike off a bridge into the river. (charles river, boston) love that dirrty water!
It was an old beater SS, about $200 into it. No big deal. No big hit.
