IIRC, the spacer comes with the hub.I need a 1.85mm spacer to fit 11sp 11-42 cassette to a road HG hub. Do the spacers come with the cassette or do I need to order it separately?
If the hub can be used with road or mtb cassettes they have a road length freehub and supply a spacer, generally.IIRC, the spacer comes with the hub.
