Before I start a disassembly of the '84 Pinarello, i'm anticipating possible problems.
TIA for your help
I think that’s an ‘S’ on the replacement BB

...the 70 mm ones are all Italian threaded. So RH threading both sides.
edit: I had a momentary lapse, but am still a good person.

Thanks for quick reply.
Previous owner was admittedly 'Not into C&V, but wanted a bike to ride L'Eroica'. Which he didn't do.

...the 73 mm ones are all Italian threaded. So RH threading both sides.

I think the 70mm ones are Italian threaded, but 68mm and 73mm are English: https://www.universalcycles.com/shop...9&category=347

Italian threaded bb's from Shimano are still in production, or are at least supplied by them, in many formats, including square-taper, Octalink and Hollowtech.
On a related note, I've never seen a French-threaded Shimano freewheel, only headsets.

After you remove it and clean the frame real well, just put it back in there if it seems to spin ok. It won't hurt a thing. (This assumes you'll just reuse the same crankset.)
Wildwood, your tubular wheels (120mm rear) are my next project. I'm going to rebuild them and try to reuse as many spokes/nipples as I can.

...FWIW, like [MENTION=20650]T-Mar[/MENTION] wrote, the Italian threaded ones were usually on stuff like 600 and Dura-Ace, so are often of high quality and worth reusing if they seem to spin well, like [MENTION=493684]SurferRosa[/MENTION] wrote.

I just bought a 36x24 UN 55 from Amazon for my Eroica bike (Is that cheating? I feel kind of dirty.)

I have a set of Italian Hollowtech II Dura Ace cups in my Colnago, so they do exist. At least they did a decade ago.

I could sure drop some weight and ramp the Italian-ness up on the Cinzia if I switched the BB from cotter to square. Hoots just thinking about a folder with that mod!
