Is the derailleur itself broken or is just the derailleur hanger broken?

there is not a heavy duty derailer, but the you can get one identical to the one you just broke for a few dollars. Look for Shimano Alivio 8 sp derailer at www.nashbar.com or some other online retailer.

Why are you guys suggesting new derailleurs? It could just be a broken hanger which is a lot cheaper than $100.

Wow is this like one of the few times to correct you. A 9 speed derailleur will work with any speed 9 and below. My Trek 4500 has a deore and it's 8 cogs.

Very true, girlscout runs a X9 with a 8speed cassette. Most of the time 8 speed stuff is cheaper than 9 speed. I should have said that in the first place.

Yeah, we need pics of what's broken, the derailer or the hanger.

That is not true. There most certainly are heavy duty derailleurs.

Hey Wolfgang. Something seems strange here. Your RD shouldn't just be snapping off like that for no reason. You may want to determine the reason your RD is failing before blindly installing yet another. Do you have any idea as to why this is happening to you???

Bet his chain is too long, he's riding in too low a gear or he put a bash guard on the bike and didn't shorten the chain. Jump off a curb (3 broken derailers in a year), the chain slaps down, rebounds and the derailer wraps up in a nice little bow and goes for a walk. Putting on a more expensive derailer would just mean a more expensive bit of junk to throw out when it biffs too

I agree, find the problem and then fix it.

If we can derive this much glee from mildly exposing an old thread, how about some real power excavation?
