I have one of these in Italian threading and the first time I looked it over I said the same thing, namely "geez, I've got to tap a bottom bracket from the drive side straight through to the other side"! A rather daunting task which I decided not to undertake, opting instead to have a machinist friend "alter" the BB - had I known the darn thing might be worth a king's ransom, I would have left it in its original problematic state!
Stronglight also produced a newer version with slightly smaller non-drive side threading, so the bottom bracket could be threaded in from the drive side and the non drive side was held in place by the lock ring. These could be used on frames which already had the bottom bracket threaded. I think Mavic's solution was a better one (IMO)!
