I think the Tenax used by Schwinn had that size. Of course, Tenax was a relabel of something else

Cromor is said to use 27.2
Zeta should also use 26.8
I can't find the spec, but i suspect that Thron uses 26.8, too.
Also can't find the spec for Aelle R (the rare butted version of Aelle) anybody out there with an "R" frame who can tell us?

I had to use a 28.5 campy front derailleur. 28.6 wouldn't tighten correctly.

I almost mentioned my Bertin earlier, which has a 26.8 seat post, but didn't want to go off-topic. That's also Reynolds 531, double-butted & "probably" metric.

Thron was designed for a 27.2mm post while Aelle R was designed for a 27.0mm post.

Have you measured the post to make sure it's properly stamped? Is the post too small and the cinch slot almost pinched shut at the top? If neither is the case, the other possibility is that Colnago installed the seat tube upside down! Putting the 0.9mm butt at the top would result in a 26.6mm post being required.
