My sub 20 pound Pinarello Opera steel bike is very nice, As is my 18.5# Litespeed and even lighter carbon Cannondale.
The bike i have been grabbing the most lately weighs 23 lbs --- its a Columbus steel De Bernardinwith a circa 2000 Veloce triple groupset, 32 spoke wheels with heavy aero profile clinchers, and a tall Nitto stem
I have lighter bikes, but something about this one trumps light weight-- its a great machine
Now - if i trade the heavy aero clinchers for tubulars on. Gl330 or equivalent rim-- and maybe swap the heavy steel turbo saddle for something titanium-- then i a, under 22 , - about what a pro level bike weighed before aluminum and carbon took over - im good with that- it rides great
