Shimano FD-8150 Ultegra Di2 Front Derailleur - 12 Speed

Ultegra R8100 – Leave Time Behind
When developing the Ultegra R8100 series, Shimano took a holistic and 100 % performance-oriented approach, because great speed means great responsibility. Faster than ever before, the 12-speed road groupset scores with unparalleled control and comfort anytime and anywhere – whether in an everyman race, on the hunt for a personal best time or on a companionable ride.

As with the Dura Ace R9200, not only does Hyperglide+ make its way into the Ultegra's components, also its Di2 parts rely on Wireless technology to simplify operation and ensure smooth shifting.

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.
