Wanted: 170mm cranks, 50/34 chainrings or crankset or chainset or whatever

Hello, I need the following:

• SRAM crankset for 73mm BSA BB (ie. MTB width, not road), 170mm, 11 speed, ideally with the 3-bolt removable spider
  
  

And one or other of the following, with a good amount of life left in them:

• (Shimano) crankset, 11 speed, HTII, 170mm, 50/34 or 48/32 or 46/30. Any GRX or 105 or Ultegra or whatever will do but 52/36 or 53/39 is no good
  
• double chainrings: 11 speed, 50/34 or 48/32, 5 bolt 110 BCD
  
  

Let me know if you've got anything. Thanks
