supposed to fit anything.
so if the primo mix cassette falls under the category of "everything" i believe it will fit.
it fit a demo perfectly
and i made the hole a bit bigger for my freecoaster
so it would fit anything and if the hole is too small you can easily make it bigger with a dremel.
But think about it, the hub must be as fat as a freecoaster so you would need to make it bigger
