Some Miche hubs have RS bearings installed that only has one seal, instead of 2RS bearings, so whatever grease inside it from the factory runs out and makes the bearing dry.
I took it apart as much as I could and it seems to have one plastic seal
will take it to shop and see if really it's the grease, I think some dirty water got in it
