I've been looking at 1x conversions and recall SRAM's marketing materials saying that they provide spacers with their X-Sync chainrings that provide correct positioning of the ring between where the inner and outer rings would be on a conventional 2x.

I'd like to buy a Rival 1x X-Sync 40T right now and none of the online shops are carrying it - just Force. I thought SRAM had been shipping Rival 1 stuff for over a year. As to the rings being available in different offsets, that would be news to me at least if you're getting them from SRAM.
SRAM has sown a bunch of confusion with all their changes in marketing terms (e.g., CX1, Force 1, Rival 1, XX, X1, XO1, etc.).
