Blasted thru a very familiar corner, forgetting that it is always full of gravel. I was going around 22mph, leaned over pretty hard, when the front wheel broke loose and turned inward, then suddenly caught the pavement again, which brought me to a complete stop and slammed me down onto my side, landing on my hip and head. It hurt, it broke a lot of gear and ripped up my clothes, and left me with lots of road rash and deep cuts. It has also left me a bit lame in corners -- I go too slow and lean too little, always remembering my crash.
