I'm looking at a Campagnolo Record double crankset. No date codes that I can see, but seller claims it's from the 60's. It's a 151 BCD. Any ideas as to vintage or, at least, range of vintage? Anyone have any ideas as to value or what the correct bottom bracket size would be? Thanks.

Hey! double post! But new question.

Value is what both you and the seller feel is a reasonable price. If he says 'make offer,' then open at $5.

The appropriate bb can be Record or Nuovo Record in 112 for 68 or 113 for 70. Spindles will say 68-SS-120 or 70-SS-120.

Does it have chainrings? Are they any good? They are hard to find. We old trackies would find them one at a time and treated them like gold, and we had 10 years of production after the road stuff stopped.

Thing about the bottom brackets for these cranks is not always the spindle length, but the cup thickness. Earlier Campagnolo bottom brackets had thin-wall cups, later BBs had thicker-walled cups. Now we are in terrotory where only the really hard-core Camposcenti dare to tread. Bottom line is, you may be able to mix and match these elements with your cranks, but may need to do a little experimentation to get a good fit, right chainline, etc. Disclaimer: This topic is not really my bag, baby, but my purpose is to point out the potential need to shop around a bit for the right BB.

Record is the thin wall stuff, Nuovo is the thick wall stuff. If it has rifling, it's Nuovo.

There is a difference in the spindles (cone to cone distance) to match the difference in the cups.

I don't have the dimensions off the top of my head, unfortunately, but bring a Japanese road spindle along to compare to any Campy spindle you find. If the Campy spindle cone-to-cone is within 1mm or so of the Japanese spindle, thick wall spindle: needs rifled cups.

If the Campy cone-to-cone is substantially more, thin wall spindle: needs plain cups.

This is assuming your Japanese spindle isn't Dura-Ace AX!

This is also ignoring Super Record (AL cups, Ti spindle).

Good luck

In the bad part of Los Angeles, they are worth nothing, in Pasadena they are worth big dollars if the rings are not worn out. spindle size depends on BB width as stated prior. Thes are pre 1968 most likely, replacement rings are the rub, a friend paid $125. for a NOS 53 tooth ring 151 BCD.

And check the chainring bolt identification, those can bring a handsome price too. Want to know more? follow the zebra striped herse, oops, wrong author.
