colnago carbitub seatpin diameter?

first, let me say it's NOT 25.0mm.

given the carbitubo was made by alan for colnago, i would have figured it to be 25.0mm. but i have a 25.0mm post (amclassic, spec verified with digital caliper), and it does not fit...much too skinny.

so i slid the 25.8mm center-section from ITM bars in and it fit fine, probably could still go a little bigger...maybe 26.0mm... will test tomorrow.

in the meantime, if anyone knows *for* *sure* the factory spec seatpin diameter for a colnago carbitubo, please post the info!

thx in advance! :-)
