Don’t forget the On One is Rear Disc Spaced, so it needs a front wheel hub that is also RDS.
The Exotic forks above are Front Disc Spaced, which can fit FDS hubbed wheels as they come, or you can convert an RDS hubbed wheel to fit using https://www.tritoncycles.co.uk/frames-forks-c6/frame-fork-spares-c152/problem-solvers-fat-fork-disc-adaptor-p11825
I’m still pissed at PX, last summer I bought a v1 Fatty front wheel that was supposed to be RDS, when I finally got around to getting the Fatty fork fitted earlier this year I discovered it was FDS… So I can currently only use a fat rear wheel, at the front I have to use my RDS FatNotFat 29er. 👿
