This did not sit well with the guys who wanted to tell their wives "I need a new frame every year, they go soft..." These were the days when you got a new frame and transferred your Campy stuff over to it, because the Campy never wore out or became obsolete.

That sounds like a very plausible theory, if the rear end is misaligned then you're always putting torque onto the road in the wrong direction and correction with the front end.
