Hi, I recently bought a american classic aluminum seatpost for my bike and it is slipping, Alot!
Before I greased it it would slip like a couple Cm every mile..after greasing, it will slip down all the way on the first big bump I hit. Very annoying since my bike is a small frame and with it all the way down my legs are all bunched up.
I can't tighten the seatpost bolt anymore. Its also not the original seatpost shim, which I broke awhile ago. It came off a iron horse bike I belive.
