English/Italian thread?

How can I tell if my bicycle has either English/Italian threading? Do I have to remove the headset and BB to find out?

where? If the BB then an Italian shell will measure 70mm wide and a British one 68mm wide. The ITA cups with both be RH thread, the BRIT one will be LH thread on the Right (drive) side.
If the headset is in question: don't worry about it; likewise for the hub threading on the rear hub with freewheel.

If the bottom bracket is Italian threaded, English cups will be obviously too small, and vice versa.

How about derailler claws for Campy record? Sorry, not my thread but I've got a situation.

Not sure I understand what your issue might be, but if it's the threading of a Campy RD claw (which would also be the same as all Campy RD hangers on dropouts) AFAIK the technical answer is that they are not the same as the ISO/JIS/just -about -everybody-but -the- French standard of M10x1mm, but the threading Campy uses is so close that nobody ever noticed. I suppose that given tolerance ranges that there will always be an exception where you find one that won't play well with the other kids.

Yeah, a Suntour claw worked just fine. Thanks.
