Ultegra/105 crankset and medium cage RD

As of 04/05 looking for:

1. Ultegra/105 crankset - Looking for the 4-bolt 110 BCD variety, ideally in black-ish and good condition. Got some TA rings I want to mount and give a go. Sorted
   
2. R7000/R8000 medium cage RD in good working order, ideally in black-ish but happy with the silver/grey variety.
   

Updated with new requirements

RD sorted. Still looking for crankset
