This is what happens...
« on: July 26, 2009, 07:23:31 PM »
This is what happens when a bombproof wheel gets a hold of a SRAM X9 SS and a 1" thick derailleur hanger.... Derailleur explodes on the trail and the hanger gets twisted....  :o

mm google sram versus shimano and watch the U tube videos at the top of the page, a video is worth about a millions words in this case.

The four cross laced mavic ex729 wheel didn't even know what happened. They have broken off entire branches in the spokes. The derailleur didn't have a chance in hell. I still can't believe I twisted the hanger too.

The hanger is designed to be a sacrifice so the frame doesn't get bent ...right?
I have never seen a dr destroyed from a wheel!  How would a dr get close enough to the wheel to get hit like that?  The only destroyed dr's I have seen are from rocks, roots etc.....not the rear wheel.

Is that covered under waranty  :)

I had something similar happen on the big climb on Gatorback. Got off-line a bit and slid left off a rock, which pushed the rear D into the wheel. I felt something go wrong and stopped pedaling. It ripped the pivot bolt out of the hanger and bent the hanger. I was able to cobble it together and keep riding, had to buy a few small parts but I'm still riding with the same rear D.

Definitely will not be riding my derailleur again... Thankfully I have a spare X9 SS that has a slight crack in it that was a back up.
 
Paul - I know they are meant to bend, but mine is a DH version which is at least twice as thick as a normal hanger. I don't even know what happened. I went down the whoop and started to pedal back up and bam it blew up.
 
Big bike is out of commission now. Frankenbike should be up by Tues/Wed and will be riding that since the big bike was too much to move in this weekend's heat.

I hear you on that...I think my big bike is retired until the weather cools down some.

Usually when a derailluer goes into your wheel it's because of a stick,a bent derailluer hangar from an earlier fall or more times than not a limit screw that was not set up correctly. I destroyed two XO derailluers in two rides, one from a stick ( destroyed der, hangar and 5 spokes in a Xmax SLR wheel) and the second from a limit screw that I didn't set right.
 A little FYI.. go to your local bike shop  ( if you bought your derailluer from them) and have them call sram. Most shops don't know, but sram will sell you a new derailluer at a crash replacement price (they do for XO I know that for sure) they might for x9. I have replaced 5 XO derailluers for customers. The last one was about 5 months ago.  Hopefully they still do it.
Good Luck

I bought it from JensonUSA or eBay - don't remember. I might call SRAM today and see what they say...if not... I am going to use my back up that is slightly cracked and use it until it explodes.
