Those Fuel hubs are in fact Aivee MT2 hubs:

I bought a pair of those with rims ZTR Flow MK2, but I will have to open them to check the number of engagement points and pawls. Superstar says 60, Aivee says 30.
BTW, Superstar moderated/censored my comments, so that is the main reason I wrote that page.
