    Anyone else shatter a 2010 X.9 pulley?

    About 5 rides in on my 2010 X.9, in a bad gear combo, and wham I snap my der hanger. No biggie, I have a spare. Swap out the hanger only to find that not only had the cage bent a bit but that the lower pulley shattered. Doh, no MacGuyver solution for a not so round wheel (2-3 teeth broke off).

    I was able to Jerry-rig up a temporary XT pulley for now to keep the bike mobile(don't get me started about SRAM and Shimano using different pulley widths. WTF ). But looking at the SRAM 09 to 10 swap the pulley was lightened, hollowed out, and obviously weakened. Now I am somewhat on the fence. I think the 09 pulley is better, but the 2010 derailleur is IMO better mechanically (revised stops, mainly).

    Just curious if anyone else has had issue.

    For the record, here are pictures of the 2009 and 2010 X.9 derailleurs. Notice the cutouts in the pulley wheel and how little plastic is actually supporting the teeth.

    I have the 2010 X9 rear derailleur on my Hi-Fi Pro and I did notice the new design. I thought it looked weak and wondered when/if it would fail.

    Looks similar to the pulleys on my X.0. Mine have not shattered

    Interesting that they carried this on X.0 as well. I think under normal operating conditions there is not much of a risk, but if you overload it the thin connecting plastic between the hub and teeth will break. I'll probably just grab a set of 09 pulleys and call it a day. Going to have my local shop call SRAM to see if they will take pitty on me, but I am not going to count on it.

    I don't have any side by side images. I had X9 in 2006-2007 model years, never had any issue. But I know a few were having issue with how the limit stops on the 2009 model was configured (one thread is buried over in the Turner forum). The 2010 has well defined bosses for the limit screws to hit. Sorry I can't nail it down any more than that

    FWIW SRAM is covering the pulley under warranty

    I've had nothing shatter on mine, although the top jockey wheel does wobble a lot. It's only a few months old and I havnt ridden a huge amount lately. Still shifts fine and everything, do they all do this after a little while or is it worth buying a replacement wheel?

    The top pulley is supposed to move by about 1mm side to side. Fahn

    My bottom wheel has worn out very quickly
    Is there any place online to get replacments?
    I heard that you can use non Sram pulleys on these new model unlike the older units
    It might get a little steep from here

    I do believe the newer 2010 X9 pulleys are the same as the X0's So what ever will fit those should fit on the X9

    happy trails...
