Hi guys,

I have got a old Italian frame from record special cycles, and i want to drive a dura ace crank.
But the frame of course has also a Italian thread. Well, my question - which bottom bracket could fit?

Thank you in advance

regards

Absolutely correct !

If you need an octalink one give me a PM ,

if it's JIS square taper you are on your own !

I've got a Shimano UN52 or UN53 with Italian threading, 107 mm axle that you can have for a nominal fee. PM me if you're interested.

There is the major issue of JIS and ISO tapers to consider too, i.e. are the Dura Ace cranks regular ones (with a JIS taper) or NJS ones (with an ISO taper). If the former then they should fit, but if they're the later then you'll need an ISO tapered BB.

Anyway, I've replied to your PM.

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.
