Bianchi classica circa 80s seat post size help
I bought my girlfriend a late 80s Bianchi Classica and its in dire need of a seat post. its Japanese made and has a decal that says Hi-Mn. i believe its strait guage tubbing but built up with some newer parts it only tips the scales at 21.1lbs.
anyway, the seat post in it measures about 26.4 with my calipers but the stem that came in it was the wrong size, so who knows if this is right. (the binder looks correct) any guesses to what it should have??
