With cassette fitted (no spacer), lock ring spun on in 3 revs, i.e. bottomed out.
Fitted the spacer and cassette, but there's not enough of the spline exposed for the smallest cog to bite into. i.e. the spacer is too big. I need a 1mm spacer.
An alternative approach might be to use one of these (with the 1.85mm spacer), which has a couple more mm of thread. Jeopardy is that:
- the 11sp sprocket isn't engaged with the freehub splines
 - the 11sp sprocket is real close to the drop out.
