Custom wheel build

Does anyone know if these spokes are the right size for the orange koxx rim on a KH/onza hub (the chunky black one as fitted to the KH06 uni’s)?

your link does not work

If you have flange spacing and height combined with your ERD you should be able to put those numbers into a spoke calculator

Odd that it links fine for me.
I think i’ll just ring unicycle uk and they’ll know the right size
