Bringing Out Shimano's Fastest Front Shifting Yet
The Di2 actuators in the front and rear derailleurs of the R9250 series enable a higher speed for a shorter movement time when changing between gears and engaging a more rapid shifting process. The Shimano Ultegra Di2 FD-R9250 front derailleur speeds up the shifting process by 45% compared to the previous generation Dura Ace model FD-R9150. This 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.
