Non-XDR cassette for SRAM AXS?

Hi! I am trying to get my Sram Force AXS equipped bike on my Wahoo Kickr.
Given that the Kickr is the '17 version and the answer from Wahoo on whether that works with their XDR driver was “upgrade to a new one”, is anyone aware of a non-XDR cassette that works with the flat top chain? I don’t need the smallest 10 cog, so any gearing would work.

I got this cassette from China,
it’s a regular 12s cassette 11~34t
my AXS cassette is 10-33,
so this one working great for me.

I just use an 11speed cassette on the standard shimano freehub body.

I do everything in erg mode so don’t need to change gears. The gears will change but it’s not pretty

So Zwfit racing will then be single speed I guess…may be good practice for my SSCX races :wink:

Rotor has 12x cassettes that work with the flat top chain and have a shimano freehub, but I am hesitant to spend $350 just for a trainer cassette. Maybe the single speed solution isn’t too bad, until some company makes a cheap “AXS trainer cassette”.

Sorry, I don’t know what Zwift races are like. Im talking about my Trainer Road experience using ERG mode.
