SRAM Rival eTap AXS

I’d love one for the winter bike. But will I actually be able to find stock of axs chains and casettes? Uncertain. I’ve heard good things about durability for road axs which makes that less of a problem.

I’m gonna stick to 11 speed electronic just because replacements are cheaper and more accessible. Atleast until 12 speed becomes the norm. But if I were to buy a new bike and had a choice between 105 and a tiny bit more for rival? I think 105 is going to be extinct at its current price range
