I did something similar once to one of my bikes. I was leaving the shop and just down the block I flatted. I walked back, and instead of grabbing a different bike, I fixed the flat. well about 3/4 of the way home while sprinting to make a light the whee cockec in the frame just like mapleleaf's. I tumbled bum over handlebars. my knapsack likely saved me from serious injury. after getting to the curb I noticed the bike was not so lucky. the rear wheel was severly tacoed. I di the stand on thing to be able to get home, and hopefully straighten it more. wheel the wheel was toast but I had to ride it to work anyway te next day. (no car) when I put a spare wheel on the bikeI discovered the frame was bent! that was one heck of fall!

gad you OK mapleleafs.
