I've got a Cannondale R600 from I think 1995? I am not for sure on that.
Nothing is bent but it is a little dinged up here and there.
It has it's original bottom bracket and headset in it, you can strip that stuff out.
I measured from the middle of the bottom bracket spindle to the top of the seat tube and it was 60cm pretty much on the dot.
Not 100% sure what this thing is worth. Make me an offer.
I've got the old Shimano components that were originally on it if you are interested as well.

Cat not included.
