I had a Fuji for a while - those stock Alex wheels are seriously cheap. I don't think I had that bike for more than 2 years before selling it and just before I did, I decided to service the rear hub because it was starting to grind a bit. I got it all apart no problems, but when I re-greased every thing and put it back together, it was so worn that there was no way I could adjust the cones to be tight enough to not wobble without making them bind. I just replaced the rear wheel before selling it. The stock one wasn't worth fixing. OTOH, the ultegra hub I have on my rain bike has survived its first rim and a ton of nasty dirty riding without even feeling gritty.
