When I purchased some TA chainrings from Mike Barry as he was closing out his stock of TA rings, I asked him about this same question. I was going to go from a Campy NR/SR double to a TA cyclotouriste double and he said it would work fine to just use the current campy BB/axle setup (offset 114.5mm axle). I haven't set that up yet to know if it works first hand, but knowing Mike's experienec with these matters, I trust it will. Hope this helps in the mix.
