Great advice here! The martial arts info is really interesting. I fell three times during my first few weeks with clipless pedals and I kept my hands on the handlebars...my instinct seems to be to try and protect the bike! These were all slow tip-overs though. If I was flying over the handlebars, I'm pretty sure I would put my arms out to try and catch myself even though I know that would not be the best idea. I try to tell myself that if I ever go flying, I should tuck and roll and maybe try to do something with my arms to protect my face. When I think about the aftermath of a big crash, I always worry about broken teeth for some reason.
