Ultegra rear shifter won’t upshift
New bike this Spring. Cable is not frayed. Been shifting flawlessly. Bike was mounted on Wahoo Kickr this morning, rode an indoor session yesterday, flawless shifting. Getting ready to ride outside this morning, I shifted into the smallest cog to make removal from the Kickr easier. (Doesn’t everyone do this?) Shifter dropped two gears and stopped two cigs short of the smallest. Hmmm... Pulled though-axle, removed bike from Kickr, reinstalled rear wheel, cannot up shift! Lever is locked like a rigid “brake only” lever. Will barely move off axis to upshift before it feels like pushing harder to force it will break it. It’s on the smallest cog. Removed wheel, tried to upshift without anything impeding the chain, no joy. Again, cable is not frayed at the shifter end. Any ideas? I’m about to pop!

Cable end ferrule (or barrel) had jumped out of the slot in the shifter. Pulled hood back, duh... still wouldn’t shift up, though. Too much tension from rear der spring. Relieved cable tension, gently pushed ratchet track with a tiny flat blade screwdriver, click-click, shifted all the way up, popped ferrule into the metal shifter cable track, done. Hope someone is helped by this.

Cable issue. Many Shimano cables will fray at the end by the shifter. Sounds like you have a rats nest in there.
