hmhm, not sure if I understood what you mean? Well, its 80 cm from seatrail to center of pedal adapter. Its 64,5 cm from seatrail to center of bb und 27,3 cm from top of tube to saddlerail. The seatpost is only 8cm inside the tube at minimum insertion...but...
I looked again more carefully. It seems that actually my impression was mislead and "the play" is actually not at the seat clamp but a little lower, where makeinu said:
the seat-stays being not welded to the seat-tube but snap into a lock for folding issues and the tube clacks against that "lock":
Still I feel the post is unusually small in diameter for the tube. The tube has to be pressed very hard. After closing the seatclamp the ***** in the tube is, at the top, a whole 1mm smaller (3mm) then at the bottom (=4mm), feels much for me. What you think?
After all it should be fine though, sorry for hassle, I will try the "suspension" idea.
