Help: what bb/headset threads does this old Pinarello frame have?

Can anyone help? The frame was bought in France (for me and it was a gift so finding and asking the seller is tricky). It is a catena lusso frame so 1980s?

Do all Pinarellos of this era have italian thread bb/headset or could it be french? My doubt is because the bb shell seems to measure 68mm

Thank you

BB shell ‘looks’ big so probs Italian but could just be the photo. Easy enough to check a bsa cup against it.

Isn’t French the same diameter as bsa?

apparently bsa is 34.8mm french 35 and italian 36 ... so yes I suppose in practice bsa and french are pretty much the same. Such small differences though and I don't have a super accurate way of measuring. do french and italian both have right-turning threads on both sides?

Yeah both are right hand thread on both cups. 68 shell definitely suggests French.

Pinarello never made frames with French threads.

Ok. This is a level of certainty that gives me confidence. I'll buy an italian bb then

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
