Niles,
Dressed out I weigh 165 lbs. At 50 I do not think I am very strong as far as the slightly above average rider goes.

As far as compensation, I am more interested to see if it is a fluke, or as you sugest things are cut so close they leave no room for a bad heat or a little to much machening etc. If so I would like to let folks know so that they can make a better judgement as to thier choices of equipment. I bought the best and thought little of failure, more on my aging skills. I have given up the riskier days of my youth when I built bikes with swaped parts and never gave a thought to compatibillity or potential failure.

Weight is important on components, however what does a few grams less matter with a couple pounds around the tummy? Blessings.
