Shimano introduces Q'auto: Electronic shifting group without a battery
EINDHOVEN, The Netherlands - Just before Eurobike kicks off, Shimano has introduced Q'auto: an electronic shifting group for everyday bikes that doesn't require an external battery. The required power is generated via the rear hub, which functions as a dynamo. The system is designed for trekking, gravel, and light urban bikes, offering both automatic and manual shifting options.
