fork take is the biggest variable and I attribute that to how Falerio was reported to do that task by Brian Baylis - it was similar to what I saw but when the Maestro performed the task there was no review. Brian reported that he added a bit more effort at the end, cranking the crown or adjacent. I believe that.
beyond, in the early 80’s the chain stays got shorter. By ‘86 the bike was quite different.
i like that bike but it is a different animal.
i lost an auction on one attributed to the late Dave Tesch- it looked like a Tesch 101.
from casual measures of bikes I could take a tape measure to- the frames that received a .5 cm stamp had a touch longer seat tube and different length top tube.
no idea on the very small or tall. I think the very small frames had compromised handling to keep the front center measure UCI compliant.
My MC53 measures 53 cm from BB center to tippy top of the seat lug, and it's about 51 cm c-c, but it's been a while since I did a careful measurement. So what you call 56's are probably MC56, and then are 54 cm c-c. And your 55s which you do not identify as Masi-sizing are most likely 55 c-c and hence MC57?
I think I would like an MC56, because my MC53 (which is 1980) is somewhat small and my best fits are 53 and 54 c-c.
