That isolates it to shifter or RDER.
You are correct. I tried your technique and found some resistance in the derailleur that I couldn't easily overcome by pulling on the cable. Not sure if this will make sense, but I'll try my best to describe: If I push the derailleur by hand to overcome the resistance, it feels like I'm pushing past some solid debris, like a pebble lodged in there. I can eventually get past it by pushing, but it feels like a physical obstacle more than just increasing tension on the cable. What could this be...is it possible to have debris of some kind lodged in there?
