The bb is a miche primato pista. Can I just swap out the cups for italian ones or do I need to swap the whole bottom bracket?

Where are you going to find the cups, and even if you find them do you really think that they would be cheaper than just getting a new BB?

Is going to order in a new italian BB and do a straight swap. I should probably give them a plug while I'm at it....

The english tap is smaller and will fall into the italian threaded bb shell. You Can tap french or English out to Italian after reaming the shell.

It can be done the other way.. but I think you would have to use a helicoil to go italian to english... and even then, could it be done? I have never seen it or heard of going Ital->Eng

But you can always tap a frame that has damaged english threads to italian.... well a steel frame that is. Others would be very suspect.

God only knows what the hell I was thinking... but I wasn't really being serious anyways... but I was still wrong.

A 6mm helicoil set is quite expensive to purchase for a seldom use situation, so I hate to Imagine what one for 1 3/8 would cost$$$$$$$$$. You could get a new frame for less.

Italian thread is larger in diameter than english.
