Ultegra R8000 RD + KMC XXSP x11 chain problem
Hello,
I have problem with pair: Shimano Ultegra R8000 RD and KMC xxsp x11 chain. Upper jockey pulley "catches" the chain. It's noticable when pedalling backwards. Here's a quick video:

RD, as the chain, are new (both less than 500 km). Previously I used this Ultegra RD with 105 5800 chain and everything worked well. Now I want to replace the chain (2 chains method) and I have such problem. With previous 105 5800 RD this KMC chain works perfectly.

Put it in a workstand and see if it does anything weird when pedalling forwards. If nothing's odd when pedalling forwards then forget it.0
