My Somec has a Delta seat post in it and based on how the paint is cracked near the pinch bolt, I would bet the diameter is too small. The seat post is beat up and the Size has been scratched off over time. I have researched online and it seems this bike should have a 27.2 seatpost.
I sanded out the top a little to smooth it out but it seems there is some build up inside the frame I will not be able to get without the correct tools. I have a couple spare posts laying around and they go in roughly 28mm but then stick pretty good.

Any recommendations of where/who to take it to?

Thanks
