The 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. This ensures that the chain never rubs. Its rigid construction guarantees swift, silent, smooth shifting even under the most demanding of conditions.
