I have been searching a bit for an exploded diagram of the brake-less nexus 8 hub, so that I might be able to figure out the mythical combination that would change the spacing to what I've anecdotally heard may go as low as 123mm.

I've googled around a bit and I've seen a few references to this, but I don't have a hub handy to reference and I'd like to know exactly which locknuts and such I'd need to remove or swap for narrower cousins.

If anyone has done this and can describe the setup, or perhaps better, has an exploded view of the hub, I'd appreciate the support.

Thanks.
