i was going to paste this link:

Bici da corsa in acciaio Campagnolo vintage eroica steel bike | eBay

and ask opinions on the frame, but i'm realizing there is very little to go on. so my question is: what, in general, does one look for in frame construction, beyond the material(s)? i've seen a lot of comments that mention stuff such as "butted, double butted", etc. i don't expect a detailed response because i'm sure most of the experts around here have explained this stuff (though i couldn't find what i was looking for on the forum i'm sure it's here), but maybe a link or something or some general thoughts.

the components attached to the frame seem really nice. is the general experience that nice components wouldn't be attached to a poor frame?

thanks in advance for any help. i've started poking around this forum because it's time for me to buy a new bike for the first time in 15 years, and now i feel like i'm in pretty deep and want to know a lot about what i'm buying and riding.
