It’s a chain

Remove the packaging slime with WD-40 then clean off the WD-40 with alcohol. Add lube and install. Supposed to work with eagle quicklinks but used the shimano one included.

Got one while they were in stock

12 speed Shimano chain.
Better to swap out your old chain before it wears out than buying a new cassette.

Looks good

I have tried Shimano and KMC for a few years on my twelve speed systems, and the Shimano is the quietest, smoothest, and most accurate shifting chain. I have never had a Shimano chain drop, even when back peddling. It's my first choice.
