Dura-Ace Does It Again — Wireless Shifting, Ergo Hoods, & Powerful Brakes

The Shimano Dura-Ace BR-R9270 Di2 12-Speed Shifter/Disc Brake set features reliable wireless shifting, enhanced braking control, and powerful stopping power.

All-new lever ergonomics on the Dura-Ace ST-R9270 dual control levers bring exceptional comfort and control to road cycling. With the fastest wireless shifting available and even more precise brake modulation, Dura-Ace resets the industry standard for performance.

Now featuring Servo Wave Action brake technology, the new Dura-Ace ST-R9270 brake lever delivers modulation and control like never before. Wireless shifting keeps your bike looking clean while offering the fastest, most precise gear changes available. All of this resides in a Dual Control Lever to employs the most advanced materials to offer lightweight and refined ergonomics that provide comfort and control for the most demanding conditions.

With an all-new design, Dura-Ace BR-R9270 hydraulic disc calipers are the most compact yet. Monobody construction ensures light weight and rigidity, proving that good things can come in small packages.

Overall Rating
Just great
