I've been reading alot about greasing the gears but have seen nothing on dealing with the bearings. I have seen replacement gears with the bearings included (probably pressed on). They appear to be sealed or dust covered so I'm asking first has anyone tried to grease them? Or, pulled off the gears and replaced? If replaced, what was the spec and source other than China(maybe German)? My bike hasn't even been delivered yet, I'm just trying to learn as much as I can.
