Shimano Alfine Di2 SW-S705R Ohjaustankokytkin oikea, black
With the Alfine Di2, Shimano has extended its first-class electronic shifting system to the urban sector. The system allows easy gear changes at the push of a button. A small, separately available servomotor on the gear hub is controlled by the gear lever and immediately initiates the shifting process. The electrical energy for this is supplied by the Di2 battery, which is available in various designs.
Switch can be positioned anywhere on the handlebars
