I broke it.

Damn.

Riding today and my read derailleur hanger explodes and the derailleur gets stuck in my spokes. How common is this?

A little background...

I bought a KHS alite 500 in February. First bike I have owned in over ten years. I didn't do much research before purchasing but I went to a LBS and it was the best out of what I tried that day. I rode it fairly often the first few weeks, but always on paved trails or in the neighborhood. Then about two months ago I bought a trailer to pull my daughter around the neighborhood and have ridden nearly every day since.

So my first question is could the added weight from pulling a trailer up neighborhood hills (lots of shifting) every day for two months stressed out the hanger? OR, how about the fact that I fell over twice yesterday, on that side of the bike. Twice. I've had my SPDs for three months and never fell, but for some reason yesterday I was a jackass with no coordination.

I've read plenty of times that you should keep a spare hanger on hand, but I always assumed this was for rough trail riding and not for a guy stuck in the neighborhood.

this happened to me once...although it was my fault.
I had bent the litte bit of frame the derailler sits on...so i bent it back....BAD IDEA
it startedto click so i stopped inspected everything seemed fine..then there was a big crack as it shot back into the wheel and teh chain snapped...I went past my friends house just before and apperently he looked up to see me skid past with tyre smoke and me shouting **** **** **** **** **** ...twas fun...25 quid to fix tho :/

Trailer should be connected on the left side, or seat post, eh? Hanger on the right side. Don't think your hanger failing has anything to do w/ pulling the trailer. You falling on the drive side, though, might have bent/weakened the hanger.

Yeah, trailer was connected to the left side. I wouldn't see how the trailer could be at fault unless it was just the extra wear and tear of pulling it up hill 80% of the time.

Ahem, a very likely candidate for the cause.

It happens. Saw a guy walk into my LBS the other week with a $4000+ carbon fiber Superfly, with his derailer tangled in his rear wheel. He thought he'd wrecked his frame, and was quite relieved to learn about derailer hangers.

Are your spokes ok? Your derailer might be ok too. If you're lucky, you'll just need to drop $30 or so to have your bike shop install a new hanger.

Spokes and derailer are fine, bike is in the shop for replacement hanger but it's going to take nearly a week since they didn't have one on hand . What am I going to do for a week?!?

(Buying a spare as well)

Hah! Spare hanger, although I've been road bike shopping for about a month.

I'm not sure if it applies to non warranty repairs but the shop does offer loaner bikes. I'll have to check up on that since today SUCKED.

I've had that happen just riding along and wham derailleur in spokes... I was on some logging land and it had just been cleared out so I assume a stick got jammed in it, but never found any evidence. when you buy a hanger buy 2
