I see several references to folks lightening up their C&V bikes. In the modern world that usually means component upgrades, i.e. 105 -> Dura Ace, carbon this and that...etc. And yes, my '09 CAAD9 (aluminum) weighs about 17.7 lbs. with
105, it's been sufficiently weight weenied
But in the C&V world where does one go to lighten up the bike?...not implying that's a goal for me. When I disassembled my Fuji Tivoli I remember remarking how relatively light the components were, Shimano Light Action ders, Dia-Compe 400 series calipers, brake levers/shifters (as opposed to brifters)...all seemed on the light side to me.
What felt heavier: frame (obviously), freewheel, chain, wheels. Are those the places that there are gains to be made or, if trying to keep a bike in a relatively period setup is there a wall one hits weight-wise with the vintage components?
