Angry pal, my breakaway frame is 10 years old and showed no sign of rust or any indication of impending failure.
To see the kind of failure you are talking about, it has to be
A) long, sustained period of neglect
Or
B) bike is used as a submarine for underwater exploration.
Knowing that little bit about you, I don't see either one of the two happening any time soon....eh...A) for sure....B) maybe.
