The Dura-Ace Di2 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.
A completely new level of reliability and braking performance is achieved with the new Dura Ace Di2 9170 disc groupset. Even under challenging weather conditions, the rider can set maximum trust in braking performance. Despite the integration of a hydraulic system, Shimano’s developers were able to keep the STI lever design slim and compact. Of course, the reach is adjustable so that the position of the levers can be individually set to suit the rider.
Decades of experience as the undisputed leader in cycling technology has culminated in the most beautiful, progressive design ever. Sleek, powerful, effective… and evolved through science. For the new Dura-Ace groupset, Shimano improved upon each and every individual component. Together they form a truly superior groupset. A perfectly balanced total system. Improving performance by maximising efficiency: that’s how Shimano is able to ensure the best for cyclists with the highest demands.
For example a standard cable configuration could be the following: 2x350 mm for shifters + 400 mm for internal battery + 1000 mm for down tube + 600 mm for front derailleur + 700 mm for rear derailleur.
