Replacement Crank for mid-80’s Ciöcc
We recently received this lovely mid-80’s Ciöcc with full Campy Victory group as a donation at Bike Works in Seattle (bikeworks.org). Everything in excellent condition, except the drivetrain needs a thorough cleaning as well as the usual cable/housing replacements and clean white bar tape.
The Campy self-extracting crank bolt worked on the DS, but the NDS not at all. And this one has left-hand threaded dust cap threads! I think we will be doing the future owner a great service by putting on a crank with normal threads there.
So what crank would the esteemed C&V crowd suggest? BTW, I’m not sure yet if the Campy BB spindle is recoverable, but a replacement Italian-threaded BB can certainly be acquired.
And I will also post inquiries as to value in that BF Forum when we’re ready to sell, but suggestions here are certainly welcome. Note that the sew-ups and their rims look nearly new!

My Vitus 979 has a Victory Crankset. I rode 40 easy miles on it yesterday.
This crankset uses 116 BCD rings; my crankset is set up with climbing-friendly 36-50 rings.
The crankarms are removed with a 7mm hex key. Yes, 7; if you use a 6, you'll strip it. There is no reason (ever) to remove the self extracting bolts.
The BB has a 111mm symmetrical spindle, with a Campagnolo (ISO) taper. If you install a JIS taper unit, the arms will sit out roughly 3mm too far out on each side.

It would be a shame to put a different crankset on there, since everything else looks to be a matched Campagnolo groupset. If I were looking at it, and the cranks had been changed, while everything else matched, it would really turn me off.
Yeah, the outer part of the self extracting bolts are left thread, but the hex part is righty-tighty/lefty-loosey on both sides.
Put "normal" crank bolts on with press-in dust caps?

Put a 110 bcd crank (use a MTB triple and use only the outer two rings). That will give the bike decent hill climbing abilities which is not a bad thing in the Pacific NW. The bike co op has to have a bunch of those floating around so that costs are zero (other than labor). Thrown in the old campy crank with the sale of the bike and let the buyer sort out what he or she wants to do. You are not going to maximize your return by paying an exorbitant amount of money for a defunct campy standard (116 bcd) to install on this bike. Keep the repair cheap and move the bike.

Yeah, unless the extractor threads in the crankarm (or the hex hole) been stripped, it should still be removable. Best option IMO is to use a 7mm hex bit socket with a big socket or torque wrench. Soak interface with penetrant first.

Can you explain how the self extracting bolt didn't work or why the nds arm didn't come off?
Did you try to remove the self extracting bolt from the crank arm by itself before trying to remove the arm? As Dave Mayer said "The crankarms are removed with a 7mm hex key. Yes, 7; if you use a 6, you'll strip it. There is no reason (ever) to remove the self extracting bolts."
Did the bolt strip the threads in the arm?
Not picturing how you weren't able to use the self extracting bolt to get the arm off.

We were able to remove the spindle+arm+NDS cup from the bike, and also the Italian-threaded fixed DS cup. So the bike is now able to accept a replacement BB and crank. I’d like to use a Campy crank since the bike is so nice and complete, but we might just end up doing as you suggest, @bikemig, with one of the many cranks we have available.
One of the lead mechanics at Bike Works has managed to separate arm from spindle, but I haven’t seen the resulting parts yet.

I wouldn’t be offended if swapped out the crank for something else (provided it was Italian) . But that’s just me,
Here’s a pic of mine, completely stock (except tires & cables, pedals which were ofmega), but mine was a “custom” build from Nashbar back in ‘85

Get a Triomphe crank. They're better looking, anyway. And it will look like the rest of the group.
Triomphe and Victory used the same bb cups. The Triomphe spindle is a little longer, maybe by 5mm.

I’m having a PM conversation with a C&V member regarding a Triomphe crank + BB, and we’re also looking at what’s in the Bike Works Campy inventory.
