I've checked the Transmission Database but couldn't see an answer so I'm hoping some knowledgeable soul may be able to help..... just bought these retro Chorus cranks which I believe are 9 speed and part of the deal included a Shimano B/B with Italian cups (seems wrong, JIS-v-ISO?), my frame has British threads so wanted confirmation if a standard 102mm axle is correct for this model, fingers crossed!

I’m using 102mm (chorus) bb with chorus double that looks just like your cranks if that helps. British thread bb.

There are more experts on here, might be worth paging @Scilly.Suffolk as well...

102mm unless the tapers have distorted.

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

For syntax highlighting, surround the code block with three backticks:

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