Joe,
The Shimano cartridge bb's are not overhauled. They are inexpensive and intended to just be replaced. Most people seem to consider the Ultegra version more durable than the Dura Ace. That is what I would probably go with. The cartridge bb's are easy. You just screw 'em in; not lockrings, no adjustment. NOTE: They do NOT need to be screwed in flush with the bb shell. 2-3 mm of threads may stick out. There was a post a couple of months ago by someone who ruined one trying to get it in flush. Just screw it in good and tight, but you don't need to force it.

I've overhauled the cup and cone 105 bb on my Bianchi a couple of times and figured I'd just keep it rolling as long as I could. Since I put cartridge bb's on my other two bikes I've decided it's just way too easy. Next time the c and c may be "bye bye". As much as I enjoy messing with my bikes (seriously) I just don't have time to fool with some things.
Regards,
Raymond
