I believe there is/was no standardization for how a manufacturers measure the weight of their bikes.
Some mfgrs weighed their bikes with pedals, some did not. Some measured a 54cm frame and used that size as their overall official weight. Others I am sure just guessed and I am sure that many just lied.
YMMV.
