Campy 12 speed chain - peen or quick link?

I've used campy chains for 6000 miles that have little elongation, but the rollers were severely worn down and the side clearances twice that of a new chain. Using a single chain that long will cause new-chain skip, even though the chain has less than .5% elongation.

If anybody is ready to pass their chain tool on for a reasonable $, let me know.

Same here.

Decided to try the 12 Missing link on my 12 speed campy. The problem is that the pins for the link catch the rear derailleur upper pulley wheel plate.This happens in all the gears. The missing link plates seem very close in width to the campy links but the pins stand too proud. Lesson learned.

I'm using a KMC 12 speed quick link with a Chorus 12 speed chain. No problem whatsoever.

That's an interesting issue...

And is interesting what the other forumite says too...

Looks like 12 speed will figure it out little by little when the guys starts using it more and more. Pls sell your record 10 stuff to me please, and really cheap too :P

I’m using one with the Record 12 group, works perfectly.

I'm also using a KMC CL552 link on my campy 12 chain. Works fine, but the width across the pins is wider than the rest of the chain. All modern links have flush pins, so they don't protrude.

A sram axs link is too narrow.

The link simplifies chain cleaning, but if that's not an issue with you, pin peening is just fine.

Except when the Park peening tool breaks, happened to me on first use, and the Campy version costs a LOT. The link just makes things easier.

VERY true (I own the Campy...absolutely the finest, most precise chain tool in the world. Period.).

Agree...use the peen tool when chain is new..take off to clean, then use a link(KMC)...

Tim, I’ve tried the kmc on a new record 12 group and the pins on the quick link
Hit the upper pulley derailleur plate. Did you have to modify anything on yours?

I wonder if there is some variation on the KMC pin width? Since it doesn’t have flush pins 0.5mm on one side or the other would be enough to explain why some aren’t having the clearance issues.

I'm using the SRAM "Eagle" version quick-link with SR-12. No problem whatsoever.
