Default What, if any were the perceived benefits of Italian BB cups?

I see that the bottom bracket shell of an Italian threaded bike is larger than normal but that it holds no more balls than a regular bottom bracket. Unscrewing of the fixed cup is possibe whilst in use. So, just what advantages/benefits were there that caused designers to use this sort of thing?

Why is it that some people simply can not reply on-topic to a simple question? When you're looking for good information and get off-topic replies it's very annoying.

I knew it would be - almost apologized for it proactively.

And while it's true that I can't seem to help myself being a smartass,
I can reply on-topic. How simple your question was remains to be seen.
I'm sorry I have no idea what the answer is. Probably Sheldon knows.

OTOH, my answer might well be substantially on the mark.

On topic :-) I suspect that the Italian Bottom Bracket was designed
with no reference to foreign devices and that is just what they came
up with.

After all the Italian BB is only about 1/24th of an inch larger then
the British :-)

ahem. Speaking for us Italians it's everyone else whose
thread is smaller than normal.

It's an historic vestige dating from the first days of
cycling. Italians used British made tooling to cut 24tpi
threads on a nice round metric bore of 36mm (not 34.8mm).

As the beloved Mr Brown noted, standards are wonderful which
is why we have so many.

You're a hypocrite. You're making an off-topic reply to your own thread.

Dan's comment was amusing and pertinent. Possibly not directly helpful
to your actual question, but it added something positive to the group.

It's bull**** when someone posts a simple request for pertinent data on a subject. No wonder so many former Usenet users have migrated to bicycling forums. Thank goodness for people like Andrew Muzi who still do reply with useful information to the topic posted.
