Peen it properly. Forget the quicklink. Especially with 12sp stuff, there is no reason to break the chain.
Are you able to clean the chain thoroughly without taking it off? How? Serious question, I just always took the chain off as it seemed impossible to clean it on the bike.

Report: I Put the KMC 12 speed chain on with connector and adjusted rear der on work stand. No problems. As told here there was rubbing 30X11 and 12 which, as agreed, is not unusual. Put the bike on the trainer and quiet as a mouse running in non-cross chaining situations. But I wanted to see how the Campy 12 speed chain compared. After fiddling with the Park CT 4.3 and getting the chain installed while the bike was on the trainer (Elite Direto) I gave it a 50 minute trial. Noticeable noise any sprocket above 17 in either chainring (50X34). I will take it off the trainer and see if rear der adjustment quites the noise. Report to follow.

Yes, but if you want squeaky sparkling clean, then no. I don't believe in getting it squeaky clean between lubes, stripping every trace of lubricant or whatnot off the chain. I use Dumond Tech Lite as my lube of choice (not the ProX stuff). I use a Park Tool Chain Cleaner with warm water and a few drops of Dawn Dishwashing liquid. Run the chain through it, rinse it with a hose, maybe take a stiff brush to the chain depending on how "sparkling" I want to get it. But the idea is just to remove and grit and grime and fine sandy particles picked up from the road. I use a tiny flat screwdriver as kind of a scraper on the pulleys to remove the gunked up stuff. Then dry it (I have compressed air), but you can just let it air dry. Then just apply a small drop to each roller bushing. Always have a super quiet drive train. I use the Park Chain Checker CC3.2. or some Vernier calipers and follow Campy's guideline of when it gets to 132.60mm, it's time to replace. As a matter of convenience, the 50% mark on the Park Chain Checker is a bit beyond Campy's guideline, but it's just easier to quickly check using this tool and close enough.

OK, seems like it's time to start using chain cleaner tool.
Thanks Calnago!

Final report. Having tired both the KMC12 and Campy 12 chains on workstand and trainer, it seems that they work equally as well through all gears. If it EVER quits snowing here I will try them on the road. Thanks to those who responded.

Thanks for the report. By any chance, did you (or at least plan to) try the Campy chain with the KMC link?

I have always used Campy chain with quick link type of connector. Looks like (for now) that is out of the question.
Yet another reason to dump Campy. They aren’t joining the 21st century.

Yes, the first thing I tired was the KMC 12 speed missing link with the Campy chain. I tired to get the missing link into a Campy link but could not. I decided not to try to force it.

I ran Campy 11 speed chain with KMC missing link for many, many, many miles. No problems at all. I assume that it will only be a matter of time until KMC produces a quick link that will work with a Campy 12 speed chain.

Hmm - I wonder what I did wrong? I tried twice to lightly press the missing link 12 into the new Campy chain. Any tips? Just to make sure, is this what you are using?

Pin length
Kmc 12 - 5.2mm
Sram eagle 12 - 5.25mm
Campagnolo 12 - 5.15mm
I don’t see why both links won’t fit campagnolo

I have just bought these missing links and notice it doesn't say Campagnolo on the packet but does on their website. There isnt a specific Campag version. I bought them to carry for emergencies because as Calnago said, theres no reason to use them with 12 speed. I have heard and I really dont know if its true that the Campag 12 speed chain is noisy and some people are using the new Sram 12 speed chains.

Ive used KMC links on Campag 11 speed with out problems but I dont reuse them like some do. KMC chains were never an improvement over Campag with 11 speed.

Let us know if they do fit. That will prove I did something wrong.
