I had a pretty bad slam the other day, i was on my way home from work, i have damn small pedals in my roadie (LOOK clones).
Since i was in work, i had my heavy shoes on, so i started sprinting for a while, and my right foot slipped, and i was standing up, so i fell, sack first into the top tube

.My hands slipped, and my head landed on the bars, i was like superman, that stupid pose, legs hanging out the back. The bike swerved around madly, i almost kept it under control, but i was going too fast, and i went over the bars (bars locked to the right and engaged front brake. I landed on the tarmac, hand first and slid for a bit, and i *think* the bike went over me. I instantly stood up, grabbed the bike and ran to the pavement, to check things out and to avoid being roadkill.
The bike was scratched here and there, the right hood was bent towards me, and both brake levers were scraped. My work trousers were ruined, the slide on the tarmac had taken care of that, both elbows skinned, knee took a bang (not good, this was already my bad knee) and both hands scratched. I felt fine, i actually found it funny (apart from the smack in the sack) and me and my riding bud couldnt stop laughing, along with passers by.
Anyway, i was wondering how often you guys crash an burn?
Plus any recommendations on the knee, the pain leaves after 10mins riding, and then ceases up again when i stop. Also when i am sitting, it constantly has to be extended or it gets real sore. Any ideas? cheers
