I know I have seen this style frame before but can't member then manufacturer. Also for reference the drop outs have incremented marks. Story behind it. I work at a bike co-op and I'm one of the only ones who love the old bikes. One of my friends saw this one come in and because of the seized seat post it probably would have been scraped but he handed it off to me to try to save because he knows I love them. Also any tips for a super seized seat post would be much appreciated.
