I have a set of 175mm Shimano 9-Speed Ultegra cranks (for splined bottom bracket) that were used for a total of about 500 miles.
They are in excellent condition. A few light scratches on the drive-side crank and a slight fading of the painted-on black Ultegra logo. (photos available - if you're a serious buyer).
I am willing to trade for a set of either Dura Ace or Ultegra 9-Speed 172.5mm cranks of equal value or will sell them to you with the 53/39 chainrings for $75 shipped.
