FOUND: 170mm Shimano 10 or 11 Speed Crank

Preferably 53/39 but I’m also fine with 50/34.

UPDATE: Found one. This place is the best, thanks!

I have a Shimano 5800 11spd Crankset 53-39 170 for sale
.

I have a Ultegra , FC-R8000, 170mm 11 speed, but the rings are: 52/36. Used but in excellent condition. I can email pics, pm me your email or text.
