i'm not sure BB spindles are all centered, you'd have to find an expert to ask.
so going from 113 to 123 doesn't necessarily mean each side is lengthened
by 5mm. could be the drive side goes up 7mm, the other side 3mm longer.
a friend here got a great deal on some "seconds" frames. why seconds?
seat tube was too tight for correct seatpost, had to be reamed/sanded
and/or shimmed. BB threads crankside were not cut as deep as should
be, could not get the BB to seat in fully. had to add a shim but then
chainline a bit too far out. did the calculations, ordered a new BB, but
the decrease on each side was not equal. same with the next one.
third one was like goldilocks.
shouldn't be as much a problem in your case, we were limited as to what
we could do with shims.
