Seat post will spin freely, but won't come out
I decided to take a quick look at a few of the lower end flip bikes that I need to get ready to sell. One is a 70's era Schwinn Varsity that is in really nice shape, save for the condition of the decals. I went to raise the seat and it was a no go. I loosed the bolt and the post will spin freely in the seat tube. There is no sign of rust or a dent in the seat tube, but the damn thing will NOT raise out of tube my more than a few millimeters.
So what are my options? I could take the seat off and clamp something stouter to the post and try to smack it out with a hammer, but wonder if anyone has a better idea?
