@pw_pw_la - interesting question…@Ryry_1985 Just curious mate, what size seatpost does your 1990 take?
I pulled the 27.2 Ti Syncros post from an early Extralight and it’s always fit quite snug. It takes some effort to install/remove and always wondered if the binder was over tightened or if a 27.0 would be better.
Just popped a 27.0 in the seat tube now and it clamps but certainly has a fair amount of play, as in it freely falls all the way down. So my guess is 27.2 despite it feeling a little harsh on my poor Syncros post
Lots of Ti-Prep, I guess! What about yours?
