I have not had anything serious in the injury department. But it could have been. I broke a collarbone and av vertabrae last Sept. Now the Vertebrae as you know could have been a problem. I was lucky though.. While I was healing I was researching and planning my next bike purchase.. I don't know if I could stop riding bikes. Buit then I don't ride competitively, I just play around so I can take it the way that I want to..
