I've broken the rails on saddles 4 times and cracked a few seatposts. Had an American Classic post adjuster break on Casitas Pass when I was alone. Found a big ball bearing on the side of the road and jammed it in there so the seat wouldn't fall off and rode into Santa Barbara standing a lot.

In a paceline of 13 riders when a dog charged into my friend and he flew like Superman and landed on his hip, severely bruising it. Like a week later he and I were climbing on Mulholland Highway and his seat fell off and he fell right on the bruised hip. He then had to finish the climb with the saddle in his pocket and ride to a friend's house to get a seatpost. He also broke the adjuster on an American Classic post.
