The Shimano Dura Ace Di2 ST-R9150 shifters have improved tactile feedback and highly customizable button functions to suit the needs of any rider or racer. A refined rubber material on the hoods gives a more confident and comfortable grip, and hidden buttons at the end of the hoods can be programmed to work the shifters or various computer functions on compatible devices.

Multi-shift can be enabled or disabled for each individual lever or button to avoid over-shifting in high-pressure situations, and compatibility with Synchro Shift means the front derailleur can be programmed to shift automatically with the rear for seamless, intuitive performance.

Compatible with 11-speed cassettes, double chainring cranksets, and mechanical brakes.

Please note: This product ships signature required.

So far the best shifters for DI 2

These feel much better then the old shifters, no phantom shifts while out of the saddle and the buttons are easier to use!
