Shimano Dura-Ace Di2 ST-R9170 2×11-Speed Shifters
Shimano Dura-Ace Di2 ST-R9170 2×11-Speed Shifters
The ST-R9170 Dual Control Levers represent the definitive 11-speed generation of Shimano’s wireless-ready electronic shifting combined with hydraulic disc braking. Built on the highly successful R9100 series platform, these shifters were the first to perfectly balance a slim, ergonomic hood shape with the internal volume required for a hydraulic reservoir. Unlike the newer 12-speed versions, the R9170 utilizes a fully wired E-Tube connection to the battery and derailleurs, ensuring rock-solid signal reliability and a never-ending battery life compared to wireless alternatives. Featuring carbon fiber lever blades and a highly tunable "Reach Adjust" and "Free Stroke" adjustment, these shifters offer a personalized, professional-grade cockpit experience for the most demanding road and cyclocross riders.
Key Features
-
Compact Ergonomics: Despite housing a hydraulic reservoir, the hood profile remains remarkably slim and similar to mechanical shifters for better hand wrap.
-
Wired Di2 Reliability: A direct E-Tube connection provides instantaneous shifting and centralized battery management for the entire system.
-
Synchro Shift Compatible: Fully programmable via the E-Tube Project app to allow for semi-synchronized or fully synchronized front and rear shifting.
-
Carbon Fiber Construction: Lightweight and rigid carbon fiber lever blades provide a premium tactile feel and exceptional braking power.
-
Top-of-Hood Buttons: Integrated "A-Buttons" under the hood covers allow for remote shifting or controlling compatible ANT+ cycling computers.
