Product details
With the Alfine Di2, Shimano has expanded its top-class electronic shifting system into the urban sector. The system allows for effortless gear changes at the push of a button. A small, separately available actuator motor at the hub is controlled by the shift lever and directly initiates the shifting process. The electrical energy for this is supplied by the Di2 battery, which is available in various designs.
The Inter-11 hub has increased the overall gear range to 409%. In comparison, the Inter-8 has a range of 307%. Additionally, the gears of the Inter-11 are spaced closer together, allowing for a more comfortable and efficient cadence.
