The FH-U6060 is a freehub specifically designed for AUTO SHIFT. Equipped with Q'AUTO technology, the FH-U6060 features a dynamo function that generates its own power, enabling battery-free Di2 auto-shifting. Inside the freehub, there are three sensors for speed, cadence, and slope. These sensors allow the intelligent Q'AUTO hub to provide precise shifting as the rider pedals. Additionally, the hub has an adaptive learning function that personalizes shifting based on the rider's manual shift operation, offering customized shifting tailored to each rider.
