Can we get a closer picture of your spokes? Non-disc side?
This was where Roger mentioned that they’re been no change to the NDS
But I don’t think that should have impacted things as the earlier pre-fixed hubs worked in a Mad4One frame.
I know @Hammer has it working.
I suspect it is likely something to do with the spokes / build unless the fixed hubs aren’t fixed and in fact worse in this area.
You may need to file your frame to have them clear like I did slight with my Flansberrium frame.
