Shimano Dura ace 9100 167.5 crank arms. They have a little pitting on the spindles but nothing major as I have been using these for 2 years without issues. Only reason why this happened is cause I ride in the rain a lot and probably should have taken them apart to clean and relube often. Also has some show rubbing on the drivetrain but covered it with some nail polish. Only selling because I got a new bike and won’t need these anymore.
