So, I recently bought a used frame an forgot to check whether or not the seatpost was stuck Turned out it was stuck, but only about two or three centimeters too low. At first I was okay with it but over time it bugged me, so I decided to cut it out. Well, today I started only to see this:
The seatpost is stuck about 20cm in the seattube and I have absolutely no idea how to get it out. I tried the usual stuff like heating the frame and putting the seatpost in a vise and turning the frame, but nothing helped. Any ideas on how to get it out there?
