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.
