If you want meaningful comparisons of frame weights, you have to be sure you're comparing frames of the same size.
. . .
For a while now I've been trying to remember to weigh any frame or fork I have in my hands that's completely bare of hardware. No BB cups, no seat post bolt, no headset.
I generally weigh frames bare except for the pressed-in parts: fork crown race, head tube bottom cup and head tube top race. I don't remove these parts unless they're overworn. Most of the frames I've bought with myself in mind are in the 60-63 cm range -- while frame size is obviously a factor, it's surprised me how little difference 3 cm of seat tube, head tube and stays seems to make.

It's a mid-1960s Cinelli; Cino had them built pretty stout.
I have not weighed this one stripped down, but based on a 60cm Cinelli f/f/hs I just weighed (and which likely has SL tubing instead of SP) that came in at 6.8 lbs., the big boy as a f/f/hs almost certainly weighs 7 lbs or a fraction more.
Oh, and it rides like a dream.
I bought a Serotta frame that's 63 cm CTT; supposedly Columbus SLP and SL; it's heavier than an equivalent-sized PX10, and all but one other frame here; 3255 g, or about 7.2 lb. It
looks light, though.
