Dura Ace 9170

Sleek, refined, and born to race, Shimano's pinnacle road groupset has been refined over generations to deliver an exceptional rider experience with unsurpassed reliability.

True Comfort

The shift levers are the centerpiece of the 9170 groupset, offering a slimmed-down hood shape that's sculpted to mesh seamlessly with your hands, and feel completely natural mile after mile.

Flawless Shifting

Third generation Di2 technology employs optional features like SyncroShift, which allows the front derailleur to shift automatically. Regardless of your preferred setup, you'll experience instant shifts under full power, every single time.

Exceptional Control

Slimmed-down flat-mount calipers are paired with Freeza rotors, which feature radiator fins to optimize heat management, ensuring powerful, yet controllable braking on the longest mountain descents.
