I’ll share a few pictures / notes from my build as it may be of help for others.
Hub is 100mm 36h
Frame is a M4O size M.
EN933 light bicycle rim (29", 3mm offset)
I’m using Sapim Race (2.0-1.8-2.0) spokes on the disc side.
Disc is 180mm with 2x1mm M4 spacer between disc and hub (my caliper measured them at 0,8mm each so it’s probably closer to 1,5mm than 2mm spacers)
Caliper is a Shimano BR-MT420 (with the corner filed off for a bit more clearance).
Picture shows the very tight clearance between spoke and caliper. Likely ~1mm.
Spacers between disc and hub is also clearly visible.
In the picture its visible how the brake disc was made to slot into the hub. Seems like a very clever trick to make the force of the braking be transferred to the hub body, and not the screws (even with spacers).
As @Joris pointed out the cranks does not seem to go against the crank-stop/spacer on the hub. I experienced the same. I did a few quick measurements and it seems the interface is missing approximately 2mm of spacers to be similar to my other hubs.
I mounted 2,5mm spacers on mine and after using 42nm torque it still did not fully close the gap / using Nimbus Venture cranks as seen in below picture. I assume a bit more would close the gap but with no manual available yet I played it safe and stopped.
I’m using Sapim D-Light (2.0-1.65-2.0) spokes on the non-disc side.
The clearance between spokes and frame is almost non-existent. It’s less than 1mm.
If I have to rebuild the wheel someday I will add some spoke head washers to bring spoke closer to the flange (it shortens the j-bend).
Be aware that the flanges on the disc and non-disc side are very different thickness. One or two spoke head washers could probably be added without issues for the non-disc side but the disc sides has no room (or need) for those as the j-bend closely follows the flænge.
Edit: I added one spoke head washer on the non-disc side flange. Now there is ~1mm clearance to the frame and the spokes follows the flanges with no visual gap
