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.
Shimano Ultegra Di2 FD-R8150 front derailleur. 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.
