Although Zeta and Aelle have a really nice ring to their names for base-level tubing.
My Giro takes a 27.2mm seatpost which would indicate an SL seat tube with a 0.6mm wall thickness.
Aelle had a 0.8mm wall thickness in the seat tubes which would have used a 27.0mm or 26.8mm seatpost.
Zeta seat tube wall thickness was 0.9mm whuch would have used a 26.6mm or 26.8mm seatpost.
I've always heard that Fomula 2 was a blend of SL and SP tubes - probably whatever they had on the shelf... Tubo del gas?
