Ultegra R8000 RD won't shift into smallest cassette sprocket. It's fine when I disconnect the cable and push manually up the cassette and let it return, so thinking probably gunked up cables causing friction somewhere?
Do you have those stupid PTFE Shimano cables?
No idea - was bought as a built bike and still on original cables. ~6000km on them. Have I just answered my own question...?
Is there a default recommendation for replacement cables?
