Here is the backbone of a 36 frame that I am re tubing for a friend. It is really messed up.
Look at the seat post, MAN O MAN! Somebody beat it in to fit a pan motor into the frame, and then tried to beat it back out. I think that the person that did this must have been on acid or some other type of drugs.
They bent the male part of the casting that the back bone slips onto, but this is not that big of a deal, I can straighten it out and return it back to stock specs.
