Fully functional Shimano Ultegra Di2 shifters / rim brake levers running Shimano's latest Di2 firmware. These will work on Shimano 10-speed and 11-speed Di2 systems; I believe the newer 12-speed Di2 uses different (thinner) wires (but they'd likely work with Shimano's wire convertor - the protocol hasn't changed). The left shifter is in great condition. As you can see from the pictures, the right shifter sustained cosmetic damage in a crash. (You can replace the damaged lever portion if you're so inclined; they're available online - they're plastic so you could also carefully sand and repaint them for a custom look).
