I only found Swiss threading weird because it is hard to find good quality BB's with the treading. Everynice NOS BB out there is either English or French and some Italian.. I never really looked into it, but does the threading direction on Swiss BB's avoid the tendency for loosening from rotational loads coming from the bearings against the cups?? Is that why they make more sense than other BB threading to you?
