We're talking about the OP going from a 57cm ETT to a 54cm ETT. The fact that people are saying there's not enough post showing on his Bianchi has everything to do with the perception of good fit being skewed by sloping TTs.
I can't understand what you're trying to say, and obviously you didn't understand what I was trying to say, either. I worry, too, that you're confusing and conflating issues, because we are not talking about the OP going from a 57cm ETT to a 54cm ETT. We were talking about moving down frame sizes, which are usually based on seat tube measurements, and I gave you three specific model examples to show how ETT can vary within a single frame size designation (though, to be fair, Breezer designates their 54cm ST frame a M/L), the effect of which is that a range of rider heights can effectively fit on any given frame. A 54 is not a 54 is not a 54. Get it?
