So the AXS derailleur and Shimano cassette play well together. I was unsure if the spacing was different on the casserole. How did you set chain length? By SRAM or Shimano specs?

I am curious as well. I’m about to do this setup myself and need to know how to best set the chain length.

My original setup was all XTR 12spd, so I used shimano chain length specs for my Shimano chain and then later swapped in the AXS derailleur, shifter.

Yes, i think the axs derailleur offers a little better shifting and a lot more bling to the bike over the straight xtr setup. I havent tried a sram chain with my setup but dont think there is much to gain in that direction.

Finally got this installed. AXS shifter, derailleur, Shimano cassette, chain, Absolute Black Hyperglide+ chainring. Works well. For chain length I set up per SRAM instructions but it was slightly too long for some reason. Went back to Shimano instructions and removed 2 links and it's perfect.

This is the exact setup I was considering. Thanks for the chainlength tip!

Logic said to set the chain up by the derailleur brand since I figured that would be the most sensitive part. It worked fine unless in the smallest cassette ring and then it skipped because the chain was too too long. It looked droopy. So I followed the directions in the link below and all is fine. Maybe try the SRAM directions first then the Shimano if needed.

Exactly what happened to me and what I did.

Always set the chain length and chain gap/ B-gap as per derailleur manufacturer instructions. We've used the Sramano mix for racing and yes, Shimano shifter and derailleur with Eagle cassette and chain works fine, you can even replace just the shifter with Shimano if you're after their 2 gear upshift.

That may have worked using sram cassette but for some reason doesn’t work in Shimano. They chain becomes too long. I used Shimano chain length with AXS derailleur, Shimano XTR cassette

I've done this and also followed the Shimano chain length guides. I am curious about the best way to set the bgap.

I thought of using the SRAM tool to do this but considering the last jump on SRAM cassettes is so much bigger than Shimano I thought that might be too big a gap. At the same time, setting the bgap too tight resulted in chain slack when in 10t.

Anyone worked this out?
