Hello matey, you can’t hide…
(whisper it quietly) a Shimano external BB tool also fits the Campy cups, you may need the Campy allen key doodah (i used to ne a techie, honest) to tighten the cranks together tho. You will certainly need a Campy compatible lockring tool.
You’ll be pleased to know I have the lot and will arrange delivery to your work thru the good mates mail network we have on request 😉
