Question about Wahoo Kickr Core 2

The supplied cassette is an 11-speed Shimano cassette that is compatible with both Shimano and SRAM 8- to 11-speed drivetrains without an adapter. An optional Wahoo SRAM XD/XDR freehub body is required for SRAM AXS and Eagle 12-speed cassettes, as these are not compatible with the standard cassette. This means that the supplied cassette is generally compatible with SRAM 11-speed systems, but a special freehub is required for 12-speed SRAM cassettes.
