My old Red AXS chain (which was perfectly quiet throughout its life) finally measured at the replacement mark, so I installed a new Red AXS chain of the same length and lubed it up.

It immediately began making a lot of noise at 9/3 crank rotation when in the small chainring
It does not make any noise on the big ring (in any gear) but does in all gears on the small chainring
The noise occurs when the chain peels away from the small chainring at the bottom. I can see/feel the noise and small clunk as each link rolls off the chainring when I put pressure on the crank. It looks like the link is sticking to the chainring for a moment rather than releasing immediately.
  • I pulled the crank and re-torqued the BB
    I reinstalled and torqued the crank
    I confirmed the chain and quick link were installed correctly
    I lubed the chain again and cleaned the chainrings
    I reversed the direction of the chain (still flattop facing out)
Any thoughts or common experiences?

Chain suck because the little ring is worn out. No chain skip on any sprockets? That's what happens when a single chain is used for too long.

I agree with what the others have said.

I measured the chain regularly, and thought I caught it in time, but looks like I was wrong
Thanks for your help...now I'll go sadly to order a new set of red chainrings.
How many miles are you all getting out of a Red AXS chain?
