I REALLY wish someone would do this.Both my current Bianchi's have 27.2's.I will eventually get a carbon frame and I would like to know once and for all if a more common 31.6 will fit.On my current Reparto course bike I am really pleased with my fitment but I am using a zero-set back seat post.Those are kind of hard to come by in 31.4.epic said:Hmm... you're right, maybe somebody should mic one of those things and see if it really is smaller than the 31.6 we all know and love.
This is what I have ben wanting to hear.I can deal with "snug".:thumbsup:jim hubbard said:31.6 will fit with some grease. I know as I built my wifes up with an easton post. I would say the fit is snug but it wasnt forced into the seat tube.
