Connex link causing drivetrain noise? (lemmy.ca)

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?

Yup. Newly waxed. The rest of the chain is articulating normally already. I'm pretty sure the link will loosen up too. My 11s chain seems to have broken-in faster. I guess the 9s chain has larger gaps and collects more wax which makes breaking it in slower. I'll loosen the link up and report back.

Yeah, I think 9 speed chains in general are unique. The problem child of the cassette word. LOL

I'd be interested in an update.

Now you're telling me about this? ...

I've been riding 10s/11s since 2010-ish. I have no recollection of 9s. Would be big mad if it can't get smooth given I paid for a 9s XT shifter. 😄

I only heard that, but don't have experience with 9s chains or cassettes. LOL Mine are either 7/8 speed or 11. LOL
