70s 80s Columbus tube
While I was searching for the source of seattube, there's a question I really wanna know.
According to the website from Columbus, 'Aelle' got the seat tube-0.8mm wall thickness which means I.D. is 27mm so that the seatpost is about 26.8mm.
'Zeta', on the other hand, got the seat tube-0.9mm wall thickness that means the seatpost is about 27mm.
Someone says my Moser Sprint(1976~8) more likely 'Aelle' tubing But what I have is 26.4mm seatpost.
(frame: 2250g, fork: 690g)
Is there a seattube of which the wall is only 1mm thick?
If you know anything about it, plz let me know.
