My 3rd ride and branch went into the lower pulley on my xo1; broke a tooth on the pulley and broke the outer cage past the threaded hole for the pulley. LBS says they can't order replacement.

Still works but obviously it's not going to guide the chain as much anymore, at least on one side.

Am I screwed?

I found the piece that broke off; I have some carbon fiber fabric and epoxy, so I could stick it back on and reinforce with additional fabric.

You can get replacement pulleys. I don't think you can get the outer cage plate for these derailleurs. You can try repairing it with the risk that if it breaks, something worse could happen, like it getting tangled up in the spokes or something. You'll have to be the judge of that. If I were attempting to fix it, I'd probably try to back it up with a CF plate wrapped to it with CF thread, all epoxied. It'd depend on the specifics of where the break is, the amount of room around it, etc...

I purchased a broken Type 2 x0 derailleur off ebay for fifty bucks. The aluminum cage fits. It's noticeably heavier (at least, in my hand!), but it works and far less likely to break. I took the rear tire off, flipped the bike upside down, undid the SRAM 1130 chain powerlock w/ the plier tool, and undid the hex head bolt that holds the cage on. There is actually a plastic piece that goes in between the cage and the rest of the derailleur. It was stuck on so I thought it was all one unit, but it's not. Once you have the bolt most of the way out, the spring inside starts bulging out and then when I was done, I lost my grip on the cage and it spun around and smacked my fingers. Ouch. Be careful.

Reinstallation took the longest as the spring fell out and I wasn't sure how to put it back together. Just put it back in, then put the cage into position. The spring is slightly bigger than the plastic receptacle sandwiched between the derailleur and the cage, so I had to work it in using the chain pliers. Just went all the way around. There's a metal stop screwed into the cage. I removed that temporarily, then slowly spun the cage around until the spring found its home inside the derailleur (there's a hole machined in the derailleur AND the cage which the ends of the spring go into). Then just screwed it all back together.

Was hoping I could avoid any derailleur adjustments, but not so lucky. Shifting is slightly off now.

Nice work man! I'm sure a few grams wont be noticeable on the trail.

Just one thing I do differently: remove the metal stop screw and allow the cage to rotate to release the spring tension before you remove the cage from the body. When you put it back together, bolt the cage on fully, then rotate it to create the spring tension, then replace the stop screw last.

Fortunately, that's a simple adjustment. What's your shifting problem?

^^^^ Good advise.

I tried scanning through those SRAM docs but I can't find the part # for a 2015 X01 11s RD tension spring. I need JUST the tension spring, nothing else. Anyone ever had to order one?

Lemme know what it's worth to you. I'll just send you the whole thing minus the cage, which broke off.

I may have left it in my spares bag in Washington, and I wont be back there until mid October.
