Just because the KMC missing link didn't break doesnt mean it didnt contribute to the chain breaking...at least theoretically.

Here is a better shot of the broken link. My guess is I may have damaged it when I first tried to break the chain with the Park tool. I recall it took a lot of force so I backed off, re-centered the pin and was then able to break the chain. It just may have taken months of riding before it finally gave way.

personally if I were considering getting the Campy chain tool, I'd get the Abbey one instead: https://www.abbeybiketools.com/colle...ade-chain-tool but same deal there: not cheap. |

Considering that where the inner link broke seems right at the KMC link plate..can't help but think wear/rubbing/interference with the link caused this.
Any chain noise, intermittent clicking before this happened?

Jenson has a 4 pack of sram eagle 12 speed links for $13. They have the best fit for the campy 12 chain. The cheap park ct-3.3 will work fine to remove excess links. If the joining pin is never used, just remove the links from the end with the virgin outer plates.

But seriously, glad you're ok. If you were standing and/or were going up a 15% grade that could have ended badly. As far as the expensive tool, dang, if you only had one bike with Campy it would be a push to fork over that much for a tool you would rarely use. That tool sounds like a pool, better to know someone who has one than to own one |

And the campagnolo chain failed?? scary... IMO you cant blame kmc for the problem, well could be a manufacturing issue with that link. The other detail is that many guys are using the campy chain with the kmc link w/o any problem.
KMC chain combo from now on? |

But at the same time, campagnolo stamps zillions of those, and if the OP got lucky he might have gotten the 1 in a million link that is not right... other people use the same combination too... so who knows, a weird accident?
Good think he did well, because that accident could have finish really bad... |

Thanks everyone for chiming in. As I mentioned I think the fault lies with me. When I first tried to break the new R12 chain, to remove the extra links, the Park pin started to bend a bit. It looked centered with the chain pin but I backed it off and tried again and was able to push the pin out. When I tried to install the special peening pin the Park tool broke. My guess is that when I first tried to break the chain the tool was not perfectly centered and may have caused the underlying damage that took months of riding before it finally gave way.
For now, I removed one link and re-used the KMC link (I know, single use) and rode again today. I still think I should get a new Chorus chain and have it properly peened. Tim |

Campy tools are nice, and nice often comes with a higher price tag. I've always used a Pedros Tutto chain tool for 11s campy, its around $50-60 +/-. Breaks the chain, peens the new pin, and Pedros says works for 12s too.
