    Bonking ... not feelin' well SRAM X-0 Rear Derailleur MidCage ->Broken

    Today when riding with my friends I pulled out my rear X-0. The carbon fiber cage was broken in half.

    Is that normal?
    It's the first time I use one and to be honest it lasted 3 rides...the price is not cheap to break one of these pieces every 2nd other weekend.

    Is there any recommendation you want to make guys? I have the midcage one and I'm not the best all mountain guy in the world, just a normal user

    Thanks,

    I learned about XO the hard way. To me there was no appreciable difference between X0 and X9. I've been rocking an X9 HARD for several years. The cage looks like it's been drug behind a truck but it's still shifting crisp. It's been so reliable despite being the ride I beat on the hardest. I'm sure it will tear off on my next ride now that I've jinxed myself, but even if it does, it doesn't owe me a THING.

    sram's warranty is fantastic have your LBS call and they may replace.

    I have yet to really use my new x.o but i assume if everything is set up correctly (i.e. too little chain) the derailleur should not just break.

    My carbon cage broke because of a forest floor stick!! Got the alloy cage as a replacement and it has held up very well. Personally I just don't think the carbon cage is strong enuff for real MTB-in.

    i find the biggest advantage in performance is found in the shifter of the x0 vs. x9. i cant tell much of a difference between derailuers. I've been sticking to x9 mid cage derailuers though, for the durability of the metal cage.

    the same high-end weight weenie gear is used for dh without issue for the most part. every derailleur will break or bend under the right conditions - except maybe the old saint.

    The X0 with the aluminum cage is WAY STRONGER, than the brittle CF one. The 20 gram difference is well worth the extended ride time.

    I had my XO CF cage break on the 2nd or 3rd ride on it. The derailleur is several years old (2003?) but I replaced the long cage with the CF medium cage a couple of years ago when I went to a 2 ring setup. SRAM warrantied the cage and sent me an alloy medium cage. It's been fine since.

    I ride so hard that I have mine made from cast iron. I use grade 8 bolts to secure it to the frame, which is made from 1.25 x .25" DOM chromoly. I still break them now and then but that's the price you pay for being xtreme. Gotta break some eggs to make an omlette, nomsayin?

    i dont know why anyone who doesnt work at a shop or ride as a pro would consider dropping that kind of cheese on a derailer if they hoped it wouldnt break. perhaps they would buy one knowing it is just as likely to break as any other derailer but want the bling so they sacrifice? i dunno..

    but for me and my 'all mtn' riding it would be silly to get anything much fancier than x7 or xt which holds up great and i dont have to work a week just to buy a new one if some unforeseen disaster should befall it.

    maybe i am just a crappy rider, i certainly have my moments, but rear derailers break! rocks and sticks dont care how expensive they are!

    i have the one with carbon outer and alu inner cage. seems to flex less and in turn have more strength. i haven't had any issues so far.

    Maybe because it came with his bike that he bought?

    Exactly Bubba74...it came with the bike...

    I want to believe that when Michael Browne, brand manager at Trek, gave the ok for this product to be assembled in the bike was because they've made enough tests to ensure that it was strong enough, am I wrong?

    Anyway, the solution is clear, X-O body with the alloy midcage of the X-9

    are they replacing it under warranty? i know the cages are like $100 from sram. might be better off getting a whole new derailleur from ebay and save your as a backup for parts.
