WTB - Shimano Ultegra or 105 road groupset 10 or 11 speed

Looking to update my 2006 road bike with some newer components. I’m looking for a 175 52/36 crank, shifters, brakes, derailleurs all in the black color. New or Used.

Thank!

I have front and rear(long cage) ultegra 8000 derailleurs, cassette and an 8000 (172.5) crankset. Might have some other misc. parts
