Like everyone else that has posted I've broken pretty much the same stuff.
However, I've got stuff brokened with no effort on my part....out in the Sierras after a long day and a pretty good meal, but before calling it quits for the night did the bear bag thing by treeing up everything smellable. In the morning found that the bears had eaten the gel seat and the helmet....not a way to start the day's ride.......
