Now that Shimano's Dura-Ace Di2 system has adopted the E-tube technology introduced in Ultegra Di2, they've decided to drop the Dura-Ace and Ultegra labels and simply identify interchangeable Di2 components by their model numbers. These Di2 ST-9071 11-Speed TT/Tri Shifters are compatible with both Ultegra Di2 10-speed and Dura-Ace Di2 11-speed systems. Combining brake levers with button shifters, the ST9071 brake lever/shifter pods let you stay low and aero during both shifting and braking. You get the same smooth, precise and virtually instantaneous shifts from the shift pods as you do from your base bar-mounted Dual Control levers.
- Fast, smooth, precise and effortless shifting at the touch of a button
- Change gears and brake from both your aero extension and Di2 Dual Control levers
- Compatible with Dura-Ace 9070 11-speed and Ultegra Di2 10-speed E-tube electronics systems
- Reach adjustments let you customize brake lever position
- Unidirectional carbon brake lever is strong and lightweight
