Check out Shimano Dura Ace FC9000 crankset
172.5 mm crank arm length.
Chain rings are 53 and 39.
This was taken off a bike I have not ridden for a while, just collecting dust.
The non-drive arm is brand new. I was using a Stages Power meter previously(also on sale, see my separate ad)
The drive crank has two minor shoe rubs. See photo
