Of course, at around 130lbs should I worry???

1) I don't know how many miles my crank had on it, but probably lots. It was a pre-77 crank purchased from the 'used' pile at a local shop. I put 1200 miles on it over about 4 months, then it broke. It had strap rub marks and scrapes in various spots. 2) For comparison, I'm just over 6ft and weigh 165lb. 3) Last year someone on the list suggested that NR cranks might be low risk for the first 10,000 miles, if I recall correctly. 4) I was extremely lucky: it broke when I was cruising through my neighborhood, standing up to start from a stop sign. It could have been much worse: the prior weekend I had sprinted out-of-the-saddle down a 5% grade trying to keep up with my triathlete neighbor who was going almost 40 mph!
