centaur double cranck with chorus/record BB?

Seems that Chorus and Record BBs are now asymmetrical, more
spindle on the drive side, with correspondingly less offset
due to crank arms.

Centaur uses the other approach, symmetrical BB with offset
arms. This leaves us with the AC-H BB, Specialites TA's
symmetrical Axix 110mm & 113mm, and Phil Wood's Campy-
compatibles. I'm going to run AC-H until it busts.

so-why does the record/chorus double use a 102mm BB and
the centaur double use a 111mm? can i use a chorus double
BB on a centaur double crank?

what about mixing triple cranks/BB? is there a way to
reduce the q-factor on a centaur triple? thanks!

thanks chad! but what about using a 102mm symmetrical BB
(record or chorus) with a centaur double? the campy site
says to use the same 111mm symmetrical BB for the double
or triple centaur where as it says to use the 102mm BB for
double and a asymmetrical 111mm for a record/chorus
triple. hmm...

Designed that way. Cannot use a 102mm BB for a crank
designed for the 111mm one, the small ring will hit
the frame.
