You need to face the BB because it isn't a sealed cartridge unit and alignment can be an issue. You'll need some old BB spanners and a new (pipe spindle) cartridge tool. You need to pull the BB apart, be carefull as the bearings are able to dislodge. screw in the non-drive side with the cartridge tool then install the drive side (remember it's reverse thread for english) with the spanner and make sure the the BB spins freely and your done. Also, don't listen to people who tell not to use Dura-Ace BB, the news ones work fine and are very durable as long as you don't ride through a river.

Is facing the BB necessary?How do you know if it's out of alignment?Even though the BB surface might not be align,The cups threads only one align direction right?The BB will be going on a Bianchi XL EV2,Have you heard any problems with using this frame.Thanks.
Well, that's hard to say.JS

I have cheated and installed a Dura-Ace without facing and it worked fine. At the very least you should remove the paint from the face of the bottom bracket shell. As far as the Bianchi goes I believe it is Italian threading which is righty tighty lefty loosey on both sides, anybody out there with this frame able to confirm this? Hope this helps.
JS,I have a follow up question above.Thanks.mannyc
