Getting a new bike with component options. Looking at Campy Centaur gruppo but I have heard the Chorus BB is much better.

Can a Chorus BB be used on Centaur triple cranks?
no - see www.branfordbike,com[nm]Leroy

Are you sure you guys aren't a little too fast with your "No". 2003 Chorus has a 111mm asymetrical BB. Why would this not work?

The new 10 speed triple bb is different.

to elaborate on the above post...

Record and Chorus doubles=102mm spindle
Centaur and below doubles=111mm symmetrical spindle

Record and Chorus triples=111mm assymmetrical spindle
Centaur and below triples=115mm spindle.

If you're looking for a high-end BB for your Centaur crankset, check out Phil Wood. They make BBs in all of the Campy compatible tapers and spindle lengths. You'll pay for it though!

Centaur and below triples with 28.6mm seat tube and all Centaur and bellow doubles use 111 mm symmetrical spindle.

Centaur and bellow triples with 32/35 mm seat tube use 115 mm symmetrical spindle.

If you don't want to spend the money on a Phil Wood BB and have a 28.6mm seat tube you might want to consider a record track BB. It has 111 mm symmetrical spindle and according to "The only difference between the 102 mm Record bb and the 111 mm track Record bb is that the alloy cups on the 111 mm version lack the thin, plastic dust seals used on the 102 mm." I can't think of any reason why this would not work. I am seriously thinking about this set up for my new bike.

You jogged my memory...Nater

and you're right about the Centaur and below triples only needing the longer spindle with the fatter seat tubes. I'm buying a Centaur double group very soon (tax return) and was really hoping to be able to use either the Chorus or Record triple BB, but I can't. I think I'll run the AC-H BB that's speced for the Centaur double and get a Phil Wood when it wears out.

The only problem I can see with you using the track BB on a road bike is the fact that the track components are really designed for indoor riding and limited outdoor track riding and aren't sealed very well at all. It's all about un-impeded speed on the track. I think you might find yourself re-building that track BB much more than you'd like to!
