Thanks winfried. Yes I could use your advice and help.

I currently have a shimano ultegra 8000 on their 50-34T and a stages watt meter on the left side arm. I put a Chris king threadfit 24mm bottom
bracket and the setup is very smooth and buttery. Very nice right now.

tried adding the etap setup and it did not work. Too bulky and the crank arms hit the deraiuller body. Also the chain is rubbing against the cage. Both problems.

I see people use very thin deraiullers for this so I appreciate the advice.

here are my pictures so far of my setup
