I just installed a Connex link to join a KMC X9 chain and I'm noticing that whenever the link goes through the derailleur hanger, it causes it to move a bit, which causes rhythmic noise. Anyone using Connex noticing this? Is it normal?

I used Endurance chip and the wax seems stronger physically. It seems that the wax that’s inside the roller on the hard side of the link causses the plates to be slightly wider than normal and when the link plates are assembled around it, there’s too much fricting between the outer plates and the inner plates.

Ah, that's an important distinction, and you're probably right! I've been using just the standard wax without additives, so it loosens up pretty quickly. I may go with the Endurance chip, but ultimately, my plan is to move to the Rex hot wax (which can be tuned, too).
