Wheel Bearings

Is there any trick to proper bearing adjustment and lubrication? I am sure the majority of us have seen this http://www.youtube.com/watch?v=KDagToxCeU4. I do realize hub and bearing quality contribute greatly to how easy a wheel spins but even the best hubs and bearings will not perform optimally if the bearings are too tight and dry. What say you all? Lp

High quality loose ball hubs, e.g shimano/campy hubs with proper grade 25 bearings or better with cones that are not pitted and with the hub adjusted as loose as possible with no play will easily destroy that wheel in the video. Things like phil wood hubs with cartridge bearings and ridiculous seals will spin like molasses. That's the price you pay for weather proofness.

Do I have to watch the video? Just count me out on who watches youtube videos for much of anything. Can't you just indicate what kind of hub you want to adjust and what you are having trouble with?

It's a wheel spinning.

well, you'll know you've put too much when the grease starts seeping out of the dust cap.
park tools covers it nicely.

No,no trouble here. Just thought there was a right way and a better way to service hubs and bearings. Lp

My thoughts exactly, BFD. Spinz, do you have a question? We all know new, well-lubed and adjusted wheels spin better than bad ones. So what do YOU need to know?

Yes, there are right things to do and wrong things to do. Take a look at the procedures on the Park site, the Sheldon Brown links, or if you're a book guy (ya know, the things with paper and no vids?) Lennard Zinn's book "The Art of Road Bike Maintenance" or "The Art of Mountain Bike Maintenance."

Three of the most wrong things to do are to adjust the bearings too tight/too loose, let the grease dry out, and leave dirt and grit inside the bearings after a dirty ride. Those can all lead to hub self-destruction.

I would add not properly inspecting bearing surfaces and reusing ball bearings to the list.
