Zeta seat tube wall thickness was 0.9mm whuch would have used a 26.6mm or 26.8mm seatpost.

I's always heard that Fomula 2 was a blend of SL and SP tubes - probably whatever they had on the shelf... Tubo del gas?


Sounds right, I have a Purple Limited built in Italy, Italian BB, Formula 2, it also takes a 27.2 seatpost.
