I'm looking for a Shimano crankset, 165mm crank arm length, mid compact (52/36), color black.

I'm selling two cranksets of my own:

Shimano Ultegra 6700, 50/34. Used. I was using it with different rings during 2017. The original rings have no more than 500 miles I think. They are in good shape.
Shimano 105 5700, 52/36, color gray. Bought about 2 weeks ago, used on a couple of rides. Didn't like the color.
