There are new RoadLink DM for the new RDs. Mine is the old RoadLink, I assume what they call "Standard": https://www.wolftoothcomponents.com/pages/roadlink-tech-page
But it looks like mine will still work, since my bike is not Direct Mount native frameset.
It's all a bit black magic.
Now if some can answer my question :o)
No idea about Sunrace. Easy to find out though - if the lockring doesn't hold the cassette down solid, you need a spacer!
