I'm selling these for a friend. Vintage 2008, give or take a year. A petite 100 lbs rider rode them for maybe 150 miles then switched to 50/34. These have sat in a box in her garage ever since. 170 mm arms, 53/39 chainrings. Many people consider these among the most beautiful cranks ever made. If you already own a pair, you might want to consider getting a backup. I had the 175 mm Chorus version of this crank, and after 15 years they started to fall apart--the threaded pedal insert began to pull away from the crank arm. My LBS says I'm not the only one. I was lucky to find a replacement--in Italy. See attached photos. I have done nothing to clean them up. Some very minor scratches.
