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 FD-R9150 Front Derailleur
The front derailleur cable routing has been adjusted to further reduce shift force. The precise and easy front derailleur set up offers more cable routing options and integrated cable tension adjustment.
Shimano Synchronized Shifting
With Synchronized Shift enabled, it is possible to control both derailleurs with just one shifter. With full Synchronized Shift, the front derailleur detects the position of the rear derailleur and automatically shifts to the most efficient gear for the best chainline, so you never have to worry about front shifting or correction shifts again.
While semi-Synchronized Shift enables you to shift the front derailleur manually, allowing you optimal more control in choosing the best gear combination for your style of riding. The system automatically takes care of the necessary correction by shifting into the right rear gear for the best chainline.
Synchronized Shift is completely compatible and customizable with E-tube.
Chain stay angle: 61-66°
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.
