I thought that's what the SPA-1 is for.

FWIW: IIRC, the C-Record (and Chorus?) had left-threaded removal threads. I think.

The tool the OP wants is a small cylinder with two pins. Never sold a ton of these, and the OP might try the C&V forum.
If he simply wants to do the job, I used to use a pair of circlip pliers.

I see Jared had already posted the question on Velobase:
https://velobase.com/ViewTool.aspx?I...67f&AbsPos=142
I’d suggest Googling Campagnolo part number 1130015 and seeing what shows up. Tracking down rare tools for 40-year-old bike parts is never easy.

This one is specifically for extractor rings and dust caps.

You're aware it is reverse threaded, right?

It just needs a peg spanner with the right size pegs, I expect some circlip pliers would work too. It would be an easy tool to make ... If it's stuck then heat should help, or soak it in penetrating oil for a few days. Unscrew clockwise (because if it unscrewed anticlockwise it would come out when you loosen the crank bolt).

IIRC the left vs right threading varies by year.

Only indirectly.
One key release cranks are all LH. Cranks that are not one key are RH. So crank arm thread direction varies by year in the sense that it depends on the model year.

[MENTION=256815]fbi[/MENTION]nHY and [MENTION=225388]Kontact[/MENTION] - My IIRC may be IDRC! I thought I read a C&V thread a while ago that stated initially LH and later RH. I haven't experienced one so it may be that a RH version wouldn't work.

As I said, ALL one key cranks were LH. You may have been confused because they stopped using one key, so cranks sold later were RH again.

Self extracting bolts like this were made before Campy by Shimano and after by everyone - all in RH thread. Campy chose to make things weird with left hand thread and 7mm wrench size. But LH should be more reliable for doing BB service in the field.
#19
All Campy self-extracting bolts that I've seen have been LH thread. Think about it: if the extractors were RH, then they would tend to unscrew themselves during arm removal.
These bolts do not need to be removed - ever. Unless some doofus used a 6mm (or SAE) hex key attempting to remove the arms, instead of a the required 7mm key. And now the extractors are uselessly mangled/stripped. Or is making a cheesy attempt to sell the crankarms and extractor bolts separately on Fleabay for extra $. This will backfire when the buyer of the crankarms cannot figure out why the threads are LH (manufacturing flaw?), and nukes the seller with negative feedback.

Didn't read the thread or see all the cranks with self extracting bolts and RH threads over the last 40 years?

I suspect that Campagnolo was suffering from "Not Invented Here" syndrome.

It absolutely prevents the turning crank bolt taking the extractor ring with it. However, Shimano had success without reversing threads.
I'm reminded of threaded BBs, where the detail oriented Brits always used LH threads on the right cup, yet the rest of the world did just fine without doing so.

THE OP ASKED ABOUT CAMPAGNOLOLO SELF EXTRACTORS. Nothing else. Campagnolo. These are all LH threaded. Don't waste any more bandwidth or anyone else's time responding to this.

Damn: somehow your posting got past my kill filter; have to fix. Once again, and consistently, you've posted a useless nonsensical piece of nothing.

This forum is just choked with the half-baked musings of people that can't be bothered to think through their own ideas. And then everyone else ends up having to deal with nonsense stated as fact about how bikes work, some of which will get repeated until somebody actually believes it.

Not that Campy has never displayed NIH syndrome, but from a pure design standpoint using a LH thread makes sense.

Except for the Swiss, anyway. And RH thread fixed cups can come loose in use.
