  • Description
  • Specifications
The DURA-ACE groupset is the result of Shimano's ongoing passion for technology. This is reflected in every single component in the groupset. All components are joined together to work as one, reinforcing each other for unparalleled performance. This is how DURA-ACE achieves ultimate supremacy.

Dura Ace Di2 ST-R9170 STI
The hydraulic Di2 ST-R9170 Dual Control levers feature a refined hood shape with svelte shared ergonomics for more rider control in race conditions, which is expanded by an optimally balanced hydraulic brake system. The ergonomically-enhanced Di2 shift levers produce a more defined shift click for a more intuitive feel and quicker shifting operation and expanded E-Tube customization allows every switch the option to independently turn on or off multi-shift. Thanks to the customizable function the levers fit any riding style and the carbon composite plastic hood material drops the weight of the whole construction.

Note: In order to ensure proper functioning of the electronic Di2 drive system, all components need the same firmware version. The optional diagnostic device allows for reading out or updating the firmware version. An operation of components with different firmware versions may cause a malfunction or loss of function.
