Weighing for me is just to give another point of comparison between the bikes. The scale I use is consistent but I don't know how accurate. But it serves what I want which is to give me weights comparative for all the bikes.
One pointless goal this winter is to get my newly picked up Lemond Versailles with it's carbon/steel frame to weigh less than my other all steel Lemonds. That means I have to beat the 18 lbs 7 ozs of the GP&GS Lemond. Right now the Versailles is 20 lbs 2 oz. I know I can pick most of that up by replacing the Bontrager Wheels with some inexpensive Fulcrum Racing 3s. No real reason to do this other than because....
