Shimano Ultegra FD-R8150 Di2 12-Speed Front Derailleur

Shimano Ultegra FD-R8150 Di2 12-Speed Front Derailleur Shimano’s latest electronic Ultegra front derailleur, the 12-speed Di2 FD-R8150, is more impressive than ever, executing full-power shifts almost instantaneously. Whether connected to the shifters wirelessly or with E-tube SD300 wires, performance is never less than stellar. Bluetooth connectivity (located in the connected rear derailleur) means that certain shifting functions can be customised to personal preference using either full or semi synchronised shifting modes that can be accessed via the app. The mech will auto-trim depending on the rear derailleur’s position for a silent drivetrain and as there are no cables to stretch or get contaminated and sticky, shifting remains flawless ride after ride.
