Stating the obvious, youve tried Simply Bearings and the like. Ebay and then Ebay.com, often very different results, dont know why. Same with Banggood and Aliexpress, often doesnt show on google search. Pin down a part number, via SM Pro etc, google that number? My world, sadly ;), pretty much revolves around tracing such items etc.
MD Racing sell SM Pro hub wheels.
That must have annoyed Talon!
If you arent sorted, maybe have a look at one of their wheel bearing kits??!!
You can always give it back.
