Shimano Ultegra FD-R8150 Di2 Front Derailleur

Highlights
Why we rate it
Fast, positive changes
Moves between rings quickly and cleanly, even under load on a climb.
Hands-off trimming
The cage tracks the rear mech position automatically, so you never hear chain rub.
Synchro Shift support
Full and semi-synchronised modes can be set up in the E-Tube app.
Compact, aero body
The smaller body tidies the seat tube area and reduces frontal area over the 11-speed design.
