Yet Another G29 P-Frame Build

Re: Spacers on a Schlumpf hub.

I read through bits and pieces of the Schlumpf 2022 Build Questions thread and now I’m more confused than before.

Should I put additional spacers on top of the existing spacer or not? Or are there spacers I can buy that precisely fit? Or no spacers at all?

In that thread there was a lot of “I did what so-and-so recommended” without saying what the recommendation even was, so I got very confused.

I’m swapping cranks to 138mm soon so I thought then would be the perfect time to solve my rattling spacers issue.
