TBF almost every Shimano hub that I service fares a lot better with being neglected than anything else. Hardly any problems other than the pressure washer crew.
My 10sp DA I just ‘checked’ - always perfect. Did nothing to them in the 15,000 all-weather km I had them.
Tiagra 4700 ... I managed to drive all the grease out in three big rides (mountains+rain). That’s my limited experience.
