The expected availability date shown above is our best estimate as to when it will be shipped to you, but this date is subject to change based on our receipt of this item from its vendor. Shipping in the continental US is free for all backorder items (for international orders, our customer service team will contact you when the item is available to ship).

Anytime prior to shipment, your backorder can be cancelled by contacting our customer service team.

The Shimano Dura Ace Di2 ST-R9170 shifters have improved tactile feedback and a hydraulic braking mechanism that's balanced for racing. 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 Di2 electronic groupsets and hydraulic brakes.
