I have many experiences with Chinese ratchet hubs. Their built-in bearings are bad. Some are bad at first before use. Some became bad after using 2-3 months (600-900 km) and need to replace. I think their bearings are not water-resistant.
So, my suggestions are
- put lubricants before start using.
- and if it goes bad after using it for a while, replace it with a good-quality one. (Though you replaced new bearing, it still cheaper)
for 60t clone ratchet, I have no issue with so far.
