Bicycle Mechanics - Campy BB Question

I just bought a Centaur compact crank and I'm currently in the process of shopping for a BB to pair it with. The obvious choice would be the matching 111mm centaur bb, but I also found a chorus "triple" BB, which also has a 111mm spindle for just a couple of dollars more. My question is this: will the Chorus triple bb be compatible with my Centaur Double? I'd also appreciate any advice on the relative merits of these, or any other compatible BB's; I'm new to this Campy thing, you see.

P.S. I'll be mating this with a shimano rear drivetrain: should I anticipate chainline issues? Should I buy the Phil Wood so as to allow myself some lateral adjustability?

Is this 2007 Campagnolo stuff? If so, like many other cranksets now, you must pair the BB and the crank.

If it is a pre-07, square tapered Campagnolo crankset, you can mix and match cranks and BBs as long as the length is compatible with the frame, components and chainline.

A little more info might help with the chainline question.

This is old square taper stuff -- I believe it's a 2005 design. As for the chain line question, I have a 9 spd (12-25) shimano cassette in the back. I thought maybe campy freehubs might set the cassette a little to the left or right of where the shimano cassette sits. If this were so, I figured the Campy Crank might be oriented to line up with a campy cassette. Does that make sense? Now that I think about it, it seems kind of unlikely that this sort of small variance could cause a major chainline problem. After all, lots of manufacturers make cranks which are compatible with campy and shimano. Probably a dumb question.

When it comes to mixing Campagnolo and Shimano, there are no dumb questions. There is a slight chainline difference between the systems but, unless you are looking for race level performance, you will probably never notice the difference.

One thing that may present itself is that the chainring tooth profiles and shift ramps are brand specific. You may experience some slower front shifting. This may be fine but this is a possibility. This will also depend on the chain you choose.

Campagnolo also makes an asymmetrical 111 mm version to fit Record 10 speed triple ring cranks. The Chorus Triple bottom bracket, like the Record one pictured above, is 2 mm longer on the chainring side than it is on the non-drive side. The chainring side double bearings sit 4 mm closer to the chainrings than they do on the 102 mm model.
This bottom bracket is designed for use with the Record Triple 10 speed cranks only. It will not work with Campagnolo Racing T, Daytona, Centaur or Veloce cranks which require a 111 mm bottom bracket that is the same length on both sides.

You need a symmetric bottom bracket.

Thanks for the help.

I am currently rebuilding my '84 Pinarello Treviso, mostly with Chorus parts (I know, it may be sacrilegious, but I like the frame, and can't afford to go with a new carbon frame right now anyway; maybe someday I will restore it back to vintage NR). I can get a good deal on a very lightly used Chorus BB (I will be using square taper Chorus cranks). Is this a better bet than using the current 1984 NR BB? Will the NR even fit? I have worked on NR cranks, but is installation of the Chorus BB something I should leave to a shop? Is there anything that I am missing that needs to be done to the frame (facing, etc, or can I just take the old one out and put the new one in?)? SInce the BB is used will I need to use some sort of Locktite on the threads (what I read suggests that this is on a new BB when you buy it, and I must assume that it may be worn off when the previous owner removed it from his bike.
