okay so ceramics are another story right?
can i clean them the same way as i clean a steel bearing?
and as far as the grease or oil goes. i removed the grease from all the bearings, and for the internal ones, just oiled them, since the done see dust, they shold be fine for a good long time.
the hub bearings will need to be cleaned much more often since i oiled them all,
all the grease, and the tires woudl barely spin 3 times before friction ground them to a hault.
