Does anyone know if a “traditional” 10 speed shimano cassette is compatible with a microspline hub? Thanks in advance.

No, Microspline is completely different.

Microspline is currently 12 speed only, perhaps in future you might get 10/11 speed microspline cassettes but I doubt it!

For what it’s worth I believe you can buy a stupidly blight XTR cassette with 11 cogs that fits Microspline but it has 12sp spacing so you still need a 12sp chain

There are adaptors you can buy that allow you to put HG cassettes on Sram XD bodies. I’m sure there’s a bit of a market for something to allow HG cassettes to be fitted to Microspline bodies too.

Really? I’ve never heard of this.

Same, got a link?

What hub is it? Some hubs can be converted by fitting a different freehub body with the correct spline design.

XD to HG adapter.

Sunrace XD to HG adapter?

That adapter is going to need careful cassette choice, I assume the Sun Race one mentioned is all on 1 carrier
