Since we run chain-in-tube, it's tricky to get a definitive answer here. But from what we can hear and make educated guesses on, external impact damage is a very real possibility. Runner-up would be shock loads; generally speaking, we didn't get enough runtime on the failed ones to make me believe it's fatigue.
