Cassette choice

Hi there!
I’m new to the zwift world, yesterday bought a wahoo kickr core and now need a cassette.

I own a Mtb, it’s a canyon exceed cf7. It has sram 10-52 cassette.

What is the best cassette for my wahoo??

Stick with a SRAM XD cassette with same or similar gearing to minimize adjustments. You will need to replace the freehub on the Kickr Core.

I can buy the sram pg-1230 right???don’t need a hub then

Yes that should work. Forgot about that one. The high gear will be noticeably lower.

What do you mean?

Assuming you are running the stock chainring, your highest (hardest) gear is currently 34x10. With the PG-1230 cassette, the highest gear will be a 34x11. That difference is enough to notice. Given the small chainring size, there’s a greater chance you will spin out in high gear.

You are right, still using the stock cassette.
So the pg-1230 is not the one I should buy? What cassette do you advice?

The PG-1230 is probably the best option for the Shimano compatible freehub. That freehub body can’t support a 10 tooth cog. If you’re trying to minimize cost, the PG-1230 is a good option. If the high gear isn’t high enough, you’d have to get the SRAM compatible freehub body that I mentioned above. That will depend on your power and desired cadence.
