SRM Dura Ace 9000 power meter. It has 52/38 rings installed, but I'll also include a 50T ring (not pictured). It also includes a K-edge chain catcher with built-in magnet since the SRM requires a magnet to work. Crankset shows signs of use but still works flawlessly. I've tried to take pictures of the wear. There are some scuffs on the end of the crank arms (most noticeably on one side) and some clear coat coming off on the crank arms as well. Battery was changed and serviced by SRM at the beginning of 2018, so I'd estimate it has about half the life left. Let me know if you have any specific questions or want pictures (I always struggle with posting pictures here).
