Damn near my wit’s end looking for a pair of these from a KH reseller. Everyone is sold out and giving different answers to explain that they will probably never come available again. Do you have a pair of these mythical unicorn bearing mounts?
I do not have them, but if you are just looking to mount the wheel on an bench to true it I know any machine shop could make a jig to do it.
Found a pair on unicycle.com KOREA! Shipping was not cheap but it was very fast. Now I can move on my wheel building projects.
