quick stab would be

170 = arm length
9/16x20 = pedal thread size

not sure re other markings and no doubt some one will advise otherwise

The 170 is crank length.

The number in the box is the date stamp - sometime in the 1980's I presume.

The F stands for something like Finesse - not important.

What you need to do is identify the cranks - have you a picture of the outside drive side?

something like this

If it's a square taper, then you'll want a campag one or another ISO standard BB. If your use a JIS standard one like a Shimano you will find the chainline will be incorrect.

Argh............................

Nearly as Nice as DA 7400 - that worked better.. STOP IT... I WENT DA in those days as Record didn't work as good..and I bought a custom built UK bike from Columbus tubes. DA was the danglies in performance.

PS that's the best ever looking chainset ever FACT.

Hence my difficulty looking at DA back then. Blahblah blah.... still OMG !

Unless the cranks are clearly marked with a European manufacturer's name like Campagnolo, Stronglight, TA, then my first guess would be that the square taper is more likely to be a JIS - so you would be better with a Shimano BB.

However with a 70mm BB shell you clearly have a bicycle with an Italian pedigree so if the cranks are original they might be ISO..... in which case a Campag BB will be a good choice, but you still need to get the spindle length right.

Do you have the old BB to check the spindle length?

From the back marks they are Campagnolo - I would hazard a guess at Athena from the 80's early 90's.

Ignore the makings on the crank arms please but these should be your cranks (click on the far right photo).

If so from a quick Google I believe they took a 111mm Iso BB spindle - can you try one out at a local bike shop?

 

[blue0cean]

thank you so much, I have a old frameset with shell frameset=68 and I mounted my crankset with my frameset by Shimano BB-6400, 600 Ultegra 68X113 , and now I want to change 1 new Legnano frameset (made in Italy with sheel frameset =70 X 36) I don't know to chose 1 available BB for new frameset (when I mount my crankset). Do you help me to chose it. I am living very far the shop accessories road bike and I must buy them by the Internet when I buy them, if I no mount them then I can't to change it
many thanks


If I chose
1) Campagnolo Nuovo Record Bottom Bracket 110 ITALIAN. will they work with Legnano frameset
