New pulleys or new derailleur?
This is off my 2011 Rockhopper. The bike has been ridden a lot. I recently replaced chain and cassette and now the chain is bouncing on the RD pulleys, which you can see are worn.
I'm not finding replacement pulleys anywhere online. (Tried one set and they were wrong ones so they are going back to Amazon.)
As you can see the top pulley has an offset. The post for the bottom pulley is built onto the hanger bracket, so I can't replace these with a simpler design.
Should I try to find replacement pulleys? I think this is the model I have, from the Sram catalog. It is the one on page 66, I think. https://www.sram.com/globalassets/do...ts-catalog.pdf
My other option would be to buy a whole new derailleur. If so, how would I know which one to get. (Hint: I would strongly welcome suggestions.) Maybe something a little better.
It is a SRAM X-7 Rear Derailleur.
Thank you very much in advance.

if you could find a lower pulley that fits, but is slightly thinner, it should work.
I'd aim for the upper pully to be the same width, but not be too concerned of the tooth count/diameter as long as it doesn't interfere with the cassette.

Universal Cycles lists everything. The only problem is that they are frequently out of stock these days of the one item you need.

OK, I admit it. I'm old-school: What's with the two offset holes on the top pulley??

Not sure what your personal experience is, but they show 3-4 different warehouses and what they have in stock, and in my experience this online info is accurate.
