Connext 11sx chain on DA 9100

So my Dura Ace chain broke at 1600 miles so I went with a Connex 11sx chain to replace it. I am now getting a jump in the 52-11 combo when the quick link goes over the top of the 11. It looks like the slightly wider quicklink is riding up the 12 sprocket. The thing is this only happens in the 11 sprocket. I don't get jumping anywhere else on the cassette. I am thinking I need to just adjust the zero point or high limit screw to better center the RD over the 11 sprocket, but I am hesitant to adjust anything there because the shifting is otherwise spot on. Can anyone think of anything else that might be causing this before I play with it?

Thanks

Might be worth trying a KMC 11sp quick link to see if that solves the problem. Doubt RD adjust will change anything unless the chain is
really off center, but a few clicks on the zero point/limit screw adjust are easy to do. Had a similar problem in the single tooth step areas of an
11-28 10spd cassette when I kept the 9 spd chain, the chain kept catching on the nest cog in the single step area, worked fine when
cog to cog step was more than 1 tooth. OTOH I have had no problems with 10spd chains on 11 spd cassettes on 3 bikes.

Not sure if my info is up to date but Connex used to make their Quicklinks with a slight curve that was meant to follow the curve of the cassette and can interfere with the cassette lockring if mounted upside down.

thanks. I didn’t pay any attention to that when i put it on. Going to look at that first thing when I get
home from work.

+1 Wipperman's instruction sheet is very clear that the link should be installed in a specific orientation.

Bingo, yes the connex links can be installed upside down. You get the 11 tooth skip to remind you.
It is one of those things you do once.
Good luck.

Thanks Everyone. I had it upside down. Flipped the QL and it went away.

But that makes me ask if this is something new with 11 speed chains. I have been using Wipperman chains since 2004 and have gone through dozens and have never seen this issue on 10 speed. If fact my gravel bike right now has the link upside down on a campy 10 speed set up with an 11 sprocket and no jumipty clicking there.

You are lucky. As I mentioned, Wipperman is quite specific about how the link is to be installed and that goes back before 10-speed.

I have curved connex links for 7/8 -speed and 9-speeds.
Been using these for many, many years.
