My wife complains that I break too much stuff. So far this month I had a broken cable, broken chain, broken Camelback (zipper) and screwy Polar HRM. I've also broken two cycle computers in the past year. But, I ride off road on not so gentle single track and hills 4 to 6 times a week (200 - 300 miles a month). Is it because I ride so much or do I have unusual bad luck or is there a possible problem with my style (I only crash hard once or twice a month) How about you other riders out there. Same situation?? My wife really wants to know.

---- not to mention new tires and brake pads every three months or so
