Shimanos new Di2 front derailleur’s operation is pioneering. Smooth shifting is guaranteed thanks to a microchip communication link with the gear levers. What’s more, shifting the rear derailleur automatically trims the front derailleur. The biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load.
