Shimano Dura-Ace Di2 ST-R9270 2×12-Speed Shifters

The ST-R9270 Dual Control Levers are the undisputed pinnacle of Shimano’s "Science of Speed" philosophy. This latest 12-speed generation introduces a semi-wireless connection, where the shifters communicate wirelessly with the derailleurs to provide a clutter-free, elite-level cockpit. The ergonomics have been radically refined with a raised hood peak and an inward-curving body to provide a more secure grip and better aerodynamic tuck. Featuring "Servo Wave" technology inherited from Shimano’s MTB brakes, these shifters offer unparalleled modulation and a lighter lever action than ever before. With a battery life of up to 2 years and a 58% faster rear shifting speed than the previous generation, the R9270 is the ultimate choice for professional-level racing and flagship bicycle builds.

Key Features

• Semi-Wireless Di2: Eliminates the need for wires running through the handlebar to the frame, ensuring a clean aesthetic and simplified assembly.

• Enhanced Ergonomics: Raised hood peaks improve leverage and hand support when riding in the "aero-hoods" position.

• Servo Wave Technology: Optimizes brake control with a shorter initial stroke and improved power modulation for technical descents.

• 12-Speed Hyperglide+: Works in harmony with the R9200 drivetrain to allow for seamless shifting even under maximum sprinting loads.

• Integrated Switches: Hidden "Third Buttons" on the hood tops for controlling ANT+ GPS head units or auxiliary shifting functions.
