I'd say Specialized is correct, the XG-1271 is flat top compatible, as is the XPLR etap derailleur.

Sram is Sram, don't believe everything they tell you. They can produce misleading info at times.

I run an AXS XPLR drivetrain on my Mason. Initially, I had a Rotor crankset on it, so ran the Eagle chain, thinking the flat top wouldn't work on the Rotor rings. It worked, but was a little noisy, and shifting to the smallest 2 cogs was slightly reluctant and slow.

Simply as an experiment, I bought a Rival flat top chain and threw it on. I didn't change anything else on the setup. Result = immediate perfect shifting and less noise.

So in my experience (n=1, etc), while an Eagle chain will 'work', it's not optimal for XPLR.

Hard to believe they are specing that combo on a $15K bike and not have it shift perfectly. Maybe a misprint on their website?

Spec does have a misprint in their copy. Pure road Sworks Creo comes with XPLR cassette and derailleur...and flat top chain. Gravel version comes with all Eagle stuff including normal Eagle chain.
