Not too much to say re chain re chain If you have the SRAM AXS 12-speed setup, it's the chain you must use. I'm still using my original chain, not the one from this purchase, and it (the original) works fine. Got this as a backup replacement for when my existing chain wears-out.
Can't comment on durability since my original is still pretty new and I haven't used this one.
Love the AXS setup. Shifting, if incredibly fast and smooth. Ergonomics are great too. You'll probably master the shifting technique in the first 1/4 mile of riding.
