To Face or Not To Face, That is the question!

I'm installing new Cranksets on our Co-Motion Speedster and the new Bottom Brackets have external bearings and our old cranksets had internal bearings. I've searched the Internet and there are opinions that one should face the bottom bracket shell and opinions that it is a waste of money. I would only have to face the Stokers since my Eccentric won't require facing.

Any opinions here?

Generally there is no need to face a bb shell unless:

The bike is a brand new "less expensive" model, (although I have seen top line bikes that needed it).
The bike just had some brazing done in the bb area and/or a new paint job.
The bike was crashed hard with enough damage to the cranks that you suspect it altered the bb face.
The bike is old, and you're just not sure it was EVER done.

My sense of Co-Motion quality is that they came from the factory properly faced and, barring any of the other situations listed above, there is no need.

One thing that FSA suggestd was that I wrap the bearing holder threads with teflon plumbers tape to make sure that they did not squeak. I did on the FSA and then later on the Shimano bearings and have not had any squeaks.

I called my LBS and they were only going to charge me $20 to face it, so I went ahead and had it done. I figured for $20, it was better to do it now, then have to take it apart again if there is any squeaks. I like the idea of using the Teflon tape, I wouldn't have thought of using it. Even though I got it faced, I will still use the tape.
