2107 trouble free miles until the last 45 miles(two flats, 1 crash) for a total of 2152 miles. Started in April, surgery in June, started on the road bikes in late August, now am recovering from the crash and can't ride for another two weeks or so. Why didn't some tell me about the bike disease? I now have a Bianchi, Trek 1400, World sport(which is to big) , 1972 sports tourer, and a Sears Free spirit, Yikes!
