Kickr Core Hub/Cassette question

I'm thinking about buying a Kickr Core to run with Zwift because my Powerbeam won't provide resistance anymore. The Kickr Core comes with the ability to put on an 11 spd Cassete. I assme, since 7/8/9 cassettes are the same size as 10 (correct me if im wrong) the spacer for a 10 spd to 11 spd hub is what I'm looking for.
Also is there a difference in the mating of a SRAM/Shimano gearset, or are they interchangeable??

The Core comes with the 1.8mm spacer you need for 8/9/10. Either SRAM or Shimano 8/9/10 cassettes will work.

You will need all the gears you can get.
if you start will a 7 speed you will learn soon why you need a 11 speed.

SRAM/Shimano are the same interface. Ignoring some newer cassette bodies. If you are using 7 speed, then you need a 4.5mm spacer. For 8+ speeds, you need the 1.8mm spacer. Those spacers are readily available, your local bike shop should have some

In ERG mode it doesn't matter. In level and simulation mode it may but on a trainer I don't worry too much about gearing and shifting anyway.

In case anybody wants to try this or is wondering if it works: I have installed my 1992 Koga Miyata Exerciser 7speed steel bike on my Wahoo Kickr Core. Of course spacers are needed to fit a 7speed cassette on the Kickr. It was running great, but the jumps between the 7 sprokets were a bit to big for me (if you're an exact cadence guy...). So I switched to an 11speed cassette and chain......and....surprise: it works!!

I'm using:

-Steel frame (126mm original spacing fits on the Kickr with a bit of force)

-Shimano 1055 rear derailleur (short)

-Shimano 1055 crankset (52/39)

-Shimano 7speed downtube shifters (for 11speed you have to switch to "friction mode" because the indexing is 7speed...)

-Shimano 105 11speed 11-28 cassette

-Shimano 105 chain (11speed)
