can't say for definite, but they seem to be clones of joytek,
novatek, quando, assess, etc......made in taiwan, probably
all in the same factory with different labels slapped on.
if so, then the bodies and flanges are fine. freehub can
take quite a bit of abuse. but the bearings may need
replacing.
when purchased here in chinaland, they come with domestic
chinese crap bearings good for only a few thousand km
lightly loaded. replacement with real taiwan sealed bearing
cartridges last mucho longero.
