I have never broken one but I have bent two on steel frames. A bad accident in a crit many years ago. And a very freak accident on a windtrainer 3 years ago.

In both cases I was able to straighten them. It's common enough that I would not buy an AL frame without a replaceable one.

I had a buddy snap one off in a wild field sprint. Luckily he wasn't injured. He is pretty strong (this greatly enhanced his reputation) and it was an ancient Bianchi that he had bought third hand.

I'd love to see THAT. I'll bet it was bent and straitened a few times before it finally snapped. The only times I've seen it happen were on MTBs.

I was riding on the road and brushed by a bush with lots of branches sticking out. One of the branches got jammed into the chain/derailleur/cogs and the hanger bent as pedalled.
I bent one once.Sintesi

Bent it back and happy days resumed. Another problem I had was the screws on the hanger coming loose. Something to watch out for.
just did in on my Serotta, not in a crashclimbo

somehow, as I got out of the saddle to go up an incline, the wheel moved or slipped and the derailleur ended up catching, flipped up and inwards towards the cassette and bent the hanger all the way up as far as it could go until the derailleur hit my cassette and I was stopped dead after a 40 mph downhill stretch. First time in 5 years I've done it.

about the wheel slipping and chalk it up to your incredible power. You brute, you you Bike killer.

I broke one on a Vitus 992. Chain shifted off the big ring and I tried to shift it back on without stopping. It caught up so I pedaled a little harder. Suddenly no resistance and the sound of parts dragging on pavement.

And of course it happens at the most unopportune time possible.

It happenend at that crappy shimano replacement pin. The pin somehow worked itself out enough to break from the link. This happened while I was standing on a climb. The derailleur caught the pin and it flipped way around and bent the hanger. This is a steel frame and I was able to bend it back. I switched to a wipperman chain after that incident.

Mine jammed due to bad adjustment and was pulled into the wheel, bending the gear hanger and mashing a side of spokes.
I bent the gear hanger back at the roadside and forgot about it after fixing the mech and wheel over the following days.
Then the other day the aluminium gear hanger snapped (due to the fatigue from the previous bend) again pulling the mech into the wheel.
I hope I am not in a vicious circle here - my chainstays now are a bit scratched up and may give way!
mine broke on a GT a couple of weeks agokcd

Doing about 15 mph and 90 rpm when suddenly, BANG! Chain, derailler, and hanger--all died during the incident. Noticed a stick hanging out of the chain/derailler. The stick must have gotten scooped-up into the chain. Called Pacific; they said 2 months to get a replacement hanger. Understand this is common for GTs.
