well...I guess something wrong with the thread on hanger.
bolt tightening go well for 2/3 but no good for last couple of turns.
it looks like stripped or mis screwed so RD hanging tilted.
I don't know what happened but...I guess it tightened wrong.
Anyway I placed an order for extra hanger
I've had the cir-clip that holds the b-adjustment stop come loose more than one SRAM derailleur. I can't tell for sure from the picture, but it certainly looks like that's a possibility. It's fairly easy to fix but be careful removing or install the cir-clip. They like to fly across the garage and hide.
