Morning. Think I have one of these, how do I check for sure on the threading? Could you tell from some pics?

 

[MartinB123]

I think it will be 73mm in diameter as opposed to the British thread of 68mm

Italian thread is 70mm shell width and British 68mm. Campagnolo Italian threaded bottom brackets will be marked "36x24T" on both ends of the bb cups. British thread bb's are marked "1.370x24T". Hope that helps.

Great - thanks!

Ah, right, here we go. Mirage, marked 36x24F, threads are good, spins nicely. The width of the body is about 73mm. Have pics on the phone but they’re too big to upload but happy to email!
Cheers

If it's Mirage, Veloce or Centaur bottom bracket then the axle length is either 111mm or 115mm for double or triple chainsets. For 102mm axle length it needs to be a Chorus or Record bottom bracket to match Chorus or Record chainsets.

Now, that's really useful info for me as well! Cheers @rikster
So looks like I've an Italian-thread, 111mm that will play nicely with Mirage, Veloce or Centaur doubles.
