Which BB for Campag Victory / Triomphe chainset?

I’m swapping Shimano biopace cranks on an 80s Italian frame for Campag Triomphe cranks. I assume the Shimano square taper is not compatible so I’ll need to look for a Campag BB. But which one? The BB shell is Italian.

I have an Italian threaded Campagnolo 101mm wide version on a Battaglin running Chorus double chainset
It needs an ISO taper, Shimano are JIS (slightly different shape on the taper ends)
I’ve a cosmetically grubby but smooth innards one in the parts bin if you can’t find one locally I’d be happy to sell (unless your Triomphe is a triple in which case you’ll need the 111 or wider bb, can’t remember the exact size)

Thanks for the offer but I think it might be 109 I need. I discovered the original Victory bb is 109 so I assume 101 is too narrow?

Ah. Bit of a minefield with bb lengths, having the same issues myself :(

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

Just like Github, a blank line must precede a code block.
