Unmatched Precision with Di2 Electronic Shifting
Thanks to its advanced microchip communication with Shimano Di2 shift levers, the FD-R9150 guarantees incredibly smooth and instantaneous front shifting, even under heavy pedalling load. The difference in speed and effort compared to mechanical shifting is substantial, every shift feels clean, controlled, and perfectly executed.
Synchronised and Semi-Synchronised Shift Compatibility
Designed for Synchronised Shift and Semi-Synchronised Shift, this front derailleur automatically manages front/rear shift coordination. Di2 technology selects the ideal gear ratio and automatically trims the front mech to eliminate chain rub, keeping your drivetrain silent and efficient while you focus on the ride ahead.
Reliable, Low-Maintenance Electronic Drivetrain
By replacing traditional cables with reliable E-Tube electrical wiring, the R9150 eliminates issues caused by cable stretch, contamination, and corrosion. The result is a front derailleur that performs flawlessly in all conditions, race after race, season after season.
Lightweight & Race-Ready Construction
Weighing just 104g, the FD-R9150 is engineered to deliver maximum performance with minimal weight. Compatible with 50–55T chainrings and offering 16T total capacity, it is the perfect upgrade for any Dura-Ace Di2 11-speed drivetrain.
Easy Braze-On Fitment
The derailleur comes in a standard braze-on mount, with adapters available for frames requiring clamp-style installation.
