I read somewhere that Record and Chorus bottom brackets can only be used with like cranks, is this true? Also, what bottom bracket(s) would work with a Centuar Crank?

Thank you for the help,

Campanolo's ACH (Aluminum Cup Hollow spindle) is what I have on my Centaur crankset.

Comes in 111mm and 115mm

What year? Up until the current models Campy used a square taper, but a different one to the really common one. Sorry, can't remember the names of them.

This is basically correct. The pre-2007 Chorus and Record BBs are similar, with the Record having a carbon shell (the Chorus is a better buy). Centaur and below take a different BB with a longer axle IIRC and cups that use a different tool. Check the Campy website where you should be able to find the exact part numbers and dimensions. There are some bargains on this stuff if you look around the web or eBay, since it is 'obsolete'.

The tool for the ACH is under 10 bucks and Nashbar has the ACH on sale now for 14.95.

I have one on my touring bike with Veloce cranks and one on my Sakae Litage with Centaur. Super smooth BB's.

WOW, this is ending up being needlessly complicated.

Pre Ultra Torque

Record/Chorus double use 102mm symmetrical
Record/Chorus triple use a 111mm asymmetrical
Centaur and below double use a 111mm symmetrical
Centaur and below triple use a 115mm asymmetrical

Hope this helps.

I was thinking about using a Phil Wood BB with Centaur cranks. Harris Cyclery has listed:
68 mm - Campagnolo Specific 110.5 mm Symmetrical
They don't list the Phil Wood 111 mm BBs as campy specific. Is this because they are adjustible to 111? I'd ask Harris, but I thought I'd get a quicker response here. Thanks.

Phil Wood makes the finest BB's in the World, end of story. Problem is that he believes that Campy uses JIS standard BB taper on it's early cranks. Campy NEVER used JIS taper on any of it's cranks ever. Stick to genuine Campy BB's. I am using a Campy Centaur Light BB. It is the black one that looks like a Chorus BB. It cost about $60 but can be had for $45 online. It is as smooth as a Record or Chorus but is in the correct length and taper. Good luck
