Three stories:
My bike got knocked over while the front wheel was out, the fork was bent inward and the dropouts were compressed. I cold-set it back into place and wrenched open the dropouts.
My buddy Ev crashed into a bollard at 20+mph, cracked a carbon fork, bend the front end of his steel roadie inward. Fixed for a few bucks by a knowledgeable bike shop owner.
A local his a bad pothole and was sent ass over elbows - the fork on his De Rosa flexed, the front tire hit the downtube, and there were ripples everywhere. He sent it to a master builder out on Long Island, who bent it all back into place.
