12 speed chains

[fogrider]

So I'm running Sram electronic shifting, it's time for a new chain and everyone makes them. KMC has gold one!

Anyone knows of issues with using non Sram chains with their drivetrains?

What Sram drivetrain are you using. MTB or Road?

Sram makes a gold chain as well!

Apparently SRAM 12 speed chains have a different roller size and yes - everything else is incompatible. But I can't confirm this, so far my only exp is with a 12spd Chorus unit (which I can confirm runs fine on an Ultegra 8000 crankset).

Wanna say only AXS and Transmission use the larger roller size. That still leaves a lot of SRAM chains that don't use the larger roller.

Pretty sure you want only a Flattop chain for AXS.

Yes, flat top is the only larger roller size chain.

SRAMs chrome treatment is apparently significantly superior in the wear category. I guess it depends on what you want to spend on a chain...

There are a couple companies that claim compatibility, KMC is one. But Sram and most all other outlets recommend a Sram Flat Top chain due to size differences already point out.

SRAM road AXS needs a SRAM flat top chain

I'm using Sram flattop chains with systems other than AXS and they are proving, for whatever reason, to be incredibly durable, even on my gravel bike, which sees pretty terrible conditions for chains. I'd just stick to them.

Angry, curious on what do you mean by other than axs. Is it shimano by any chance?

AXS chain works with Campy 12.

In my experience, KMC chains are a little noisier, but they work fine.
