The new Dura Ace from Shimano is the answer to the question many professionals and ambitious amateurs have about whether and how the already immensely high level of performance could be further enhanced. Each individual Dura Ace R9170 component is designed to work as efficiently as possible with all other components of the system. This clearly reflects the core of Shimano's philosophy of system-developed components. The result is called System Supremacy - the superiority of the system over the sum of its parts.

The Shimano Dura Ace Di2 brake-shift lever features an ideally ergonomic cover. The new shape provides you with more control and confidence even under race conditions. The newly adjusted brake lever shape surprises with a direct contact point, increased stiffness, and shift buttons that respond with a defined click feel. This leads to more intuitive, targeted, and faster shifting operations, aided by the newly designed ergonomic lever position. Additionally, Shimano offers fine adjustment options on the brake lever, allowing you to customize it to your personal needs and preferences at any time.
