Selling a slightly used (about 600 miles) 12-speed Ultegra 8100 crankset (172.5mm crankarms) with a Stages Gen 3 single-leg power meter. The 52-36 chainrings are in great shape. There is a bit of shoe rub on the drive side crankarm but if you pedal fast enough you will never even notice it. Asking $535 shipped.
