Bent downtube?
I found a 58cm Centurion lemans with tange 900 tubes at a thrift store. The bike is in very good shape ,wheels, fork , bars , no signs of a crash. I started to break it down for rebuild and found a bulge just behind the head tube lug on the underside of the downtube. It almost looks like it was made that way
maybe to tweak the geometry, or maybe the bike ran into a wall .But like I say all of the components are in great shape and the fork is not even scratched. Anyone seen a frame with a similar bend ?
