Seat post sliding down in the seat tube... Any tips?
Every several miles it goes down inch or so. I'm using QC clamp, cleaned all the old grease from seat post and tube... I can't tight clamp any harder ...
I'm a pretty heavy rider ( 260 or so ) and this bike is used mostly on flat and not bumpy trails.
Years ago, I remember that all seat posts were machined to file like finish. New ones are shiny and "slippery".
I'm using older rockshox suspension seat post with very slippery finish...
