|Reconditioning an Ultegra Bottom Bracket||LeGrimper|

|My BB has just given up the ghost but I was wondering if you could pull the thing apart.
I would be interested in seeing what gave out.
I have removed the first outer seal but think it would probably be better to get a little advice before I destroy the thing.
I know Shimano claim they ARE NOT serviceable but then again they would wouldnt they?

|I tried this too, couldn't put it back together correctly. It's pretty much toast if you rip it apart.|

|The Ultegra Cart. bb's are not rebuildable. They are so reasonable, why waste the time.|

|A long time ago, JS and Grzy got in some war about some real important detail of an Ultegra BB. One of them took it apart and put it back together again (and posted pictures proving whatever point was being made). So perhaps it can be done. Why though? They only cost $35-$40 and are pretty much disposable. Is it worth the trouble? What if it falls apart when you're 43 miles from home?|

|How many miles can an Ultegra bottom bracket be expected to last? I have around 10k on mine. I'm not noticing any problems but I guess I'm just starting to wonder when it's going to die.

|Mine lasted around 12K. It started to creak and when the LBS checked over the bike before the season for all the usual, brakes, BB etc it was very rough and had a notch in it.
Maybe it got some water or like I said maybe I was unlucky. Got another Ultegra BB but will also order a Bill Shook BB and get that into there in the near future as it is serviceable and more importantly rebuildable and lighter than DuraACe to.
The bike felt sooooo light without a BB in it, you wish you didnt have to run one!
The LBS also taped the threads this time around which should help a little.
Looking forward to creak free riding.
