The Di2 actuators in the front and rear derailleurs of the current Ultegra series enable a significantly higher movement speed for a shorter movement time when changing gears and correspondingly rapid shifting processes.
The Shimano Ultegra Di2 FD-R8150 front derailleur speeds up the shifting process by 45 % compared to the previous generation Dura Ace model FD-R9150. The front derailleur which has also become more compact in its dimensions is thus not only faster than ever before, but also guarantees highly precise functionality under all conditions.
