I’ve never been guilty of building a ~20 lb road bike, LOL. That said, if you’re not starting with light wheels and tires, then nothing else matters because rotating mass is where you feel it. Although I won’t be jumping on the TPU tube bandwagon - got one as an experiment and the valve just plain fell off during installation. Anyway, light wheels in the $500-$1000 range, and light tires like RH, will make even a pig of a heavy frame feel light when riding on the flats.
Then per Bill’s remarks, it’s a method of looking at every component. Crank, BB, brakes, handlebars, and so forth. I wonder how many folks are achieving light weight with a Brooks saddle, versus anything else where a plastic frame drops a lot of ounces.
