In reference to the last response, all answers were very good except for
the final one. Neither Shimano's New 600 EX or their Dura Ace hubs are
sealed. They are both a sealed mechanism hub which means there is a
labrynth seal around the dust cap to help keep contaminants out. Good
sealed bearing hubs are made by Specialized, Bulls-Eye, Phil Wood,
Suntour, plus countless others. If you're thinking of using sealed 
bearing hubs though, be prepared to replace the bent axles that plague
these hubs. What's wrong with cone and cup hubs anyway?  Also, a note
on ultra freewheels, as long as a fairly tight freewheel is used (no
larger than 24 teeth) they will shift fine with a short cage japanese
derailleur. Don't use an ultra FW for touring gears though, you'll
overshift every time!
