Just wondering. Everyone talks about toughness and durability in a touring bike frame. Who's actually broken one? One that wasn't bent or damaged to start with? I've broken a low-end Trek 830 after nine years of serious abuse mountain biking (and they honored their warranty, no problem), but other than that, I've read of one touring frame that broke and it had been dinged on the seat tube, and that failed many miles (years?) afterward.
At what point is enough—enough? I think people are into over-kill on this bit and place way too much stock in it. If you tour off-road, that's a different matter.
So, c'mon, let's hear about broken frames.
