Guess I need to spend some more time working on the post then. I was able to get it to turn about 45 degrees in both directions, but not make any headway vertically it before I gave up.

The 600 group on it has 93-94 date codes, failed to mention that. All the parts are newer than the frame and fork. The original owner said he had it built by Colorado Cyclist in the mid 90s and the frame was unused stock at that time.

It's a really nice ride, if it's not sellable with a frozen seat post I guess I will just suffer and keep it.
