The statement was actually that 105 was 1 pound heavier than Dura-Ace. Go back a page or two and look, I'll wait right here.
I think it is reasonable to assume we are comparing 5700 to 7900 mechanical. *YOU* were the one who posted a link and said it was 396g difference, not anyone else. I have no idea if that is accurate or not, but I simply converted that into pounds and commented that .87 pounds is fairly close to 1 pound.
I'm not sure if you're just angry or what... but these rants just make you look silly.
