Can anyone help me diagnose this sound? It's driving me crazy. I'm no mechanic, so there might be something obvious I'm missing here, but I'm at a loss. The sound is much worse when I'm actually riding rather than turning the crank.
A couple notes:
-it only happens in the smaller cogs, 8-12, and mostly just when I'm in the large chainring up front
-i've indexed to both extremes and the sound hasn't changed up until the point it's caused to switch into another gear. I've tightened and loosened the B-screw and it doesn't seem to have any effect. I've also checked and cleaned the pulleys and cassette and everything seems fine
-it sounds to me like the chain is grinding on something but it really doesn't appear to be touching either derailleur
-Sram Rival AXS 2×12, if it matters

Is the chain routed through the derailleur properly? Sounds like it’s rubbing against the folded metal tab between the jockey wheels.
Try dialing in the micro adjust. I have the same drivetrain (tho the Force version) and it is just kinda noisy in those gears. Noisy enough SRAM offers these: https://www.universalcycles.com/shopping/product_details.php?id=108916
