I’ve mangled mine (non t-type). I see that I can buy the inner but not the outer plate as a spare. I’ve found this https://ratiotechnology.com/product/sr52x-derailleur-cage/ but are there other alternatives? Maybe something a bit more oem looking?
What issue were you trying to fix out of interest?
I’ve just spotted that Garbaruk have one too.

I got a stick stuck in the cage of my XX1 AXS and it snapped the front part which SRAM didn't have a replacement part. Fitted the Ratio cage and it's still going strong. No problems with it.
+1 for Ratio.
Even using microtone I can't get the shifting as good as it was when new. I've fitted a new chain, chainring, cassette, UDH and the Ratio cage which hasn't made any difference so I suspect it's the mech itself at fault. It has taken a few knocks over the past 4K miles...
Leap are doing 3D printed cages now, with ot without jockey wheels. The Ratio cage looks better.
