Mine was a learning curve: before clipless every time I stopped I put both feet down. No matter how many times I had "practiced" with my clipless, the first time I went to stop fast I tried to put both feet down again. The last time I fell I was stopped with one foot down. When I unclipped the other foot and put it down the sidewalk was sloped and I didn't know that.......Oops! lol - not really the pedals fault.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
