The FH-U6060 is a cassette hub specifically developed for AUTO SHIFT. The hub FH-U6060, equipped with Q'AUTO technology, features a dynamo function for self-generation of power, enabling automatic shifting via SHIMANO Di2 without using a battery. Inside the cassette hub, three sensors for speed, cadence, and gradient are integrated. Thanks to these sensors, the intelligent Q'AUTO hub shifts precisely while the rider pedals. Additionally, the hub has an adaptive learning function that adjusts shifting based on the rider's manual shifting actions, allowing for precisely tuned shifting tailored to each individual rider.
