Anyone of you who had the same experience post chain waxing and knows how to fix and avoid in the future?
I’m going to straight up guess you installed both chains incorrectly, perhaps going around the outside of the guard on the derailleur cage? Regardless, I don’t think this has anything to do with how you lubed your chain. (I wax most of my chains and I don’t do anything special – don’t wipe them down etc.)
Had that the first time I reinstalled the chain. On the upper wheel outside the cage. Fixed that immediately, now its correctly installed.
