Garth,
The was probably some grit in the grease or in the hub and it just got pulverized after a day of riding and now will polish the races. As far as the sealed bearing go you can pop the seal, clean and regrease the bearings. Don't forget to put the seal back on. See, they aren't all that bad even though it is a newer concept.

It feels almost as if there is a piece of dirt in the bearing that I did not feel before. Often the feel will return to smooth after running the bearings on the road for a day. What is up with this? I don't understand the mechanism, nor do I think it is neccessary to to use new balls for every overhaul. One other related matter. What are we supposed to do with sealed cartridge bearings such as Phil Woods or old Suntour? There appears to be no way to get new grease into the bearings. This seems counter to proper maintenance rather than beneficial.
