Compact and faster than ever before, the Ultegra R8150 front derailleur offers shifting with digital precision in all conditions. By combining Shimano's new Di2 platform with the road version of Hyperglide+, the Ultegra R8150 front derailleur shifts between chainrings as quickly and seamlessly as no other model on the market.

E-Tube Project: The E-Tube Project app developed by Shimano for mobile devices features functions for customizing the bike, updating firmware, and maintenance via a wireless connection to the bike. More detailed bike maintenance can be achieved by connecting the bike to the E-Tube Project app for Windows V4 using a cable.

Hyperglide+: Hyperglide+ is the starting aid for the next-generation MTB experience and is now also available in Shimano's road series. It enables smooth pedaling on virtually any terrain for the first time. The completely redesigned drivetrain with a specially developed chain allows for faster shifting, efficient power transfer, and unprecedented chain stability. It precisely determines the optimal moment for gear changes, ensuring smooth operation. This makes it easier for riders to adapt to abruptly changing terrain conditions. Hyperglide+ helps riders confidently tackle rough paths. It dampens pedal impact and reduces shift times by a third compared to the current HG system.
