Does anyone know anything about these? I have only seen 5 stars and that seems to be what most are. Is everything compatible between the two? Will I be able to use the same bearrings axles variators and such?

Nope the 6 star mags are compatible with the rims with spokes. So the axles and brakeshoes are in fact smaller. The only thing that is the same for both wheels are the gearboxes from the back wheel.
