Product Description
The new Dura Ace from Shimano is answers the question of many pros and ambitious amateurs as to whether and how the current, immensely high level of performance could be further increased. Each individual Dura Ace R9100 component is designed to work as efficiently as possible with all other components of the system. This shows the core of Shimano's component-developed-as-a-system philosophy particularly clearly. The result is called SYSTEM SUPREMACY - the superiority of the system over the sum of the individual parts.The Shimano Dura Ace Di2 brake lever has an ideal ergonomic cover. The new design gives you more control and confidence even under racing conditions. The newly adapted brake lever shape surprises with a direct contact point, more rigidity and shift paddles that respond with a defined click feel. This leads to more intuitively targeted, faster shifting processes, favoured by the redesigned ergonomic shift lever position. Shimano also offers fine adjustment options on the brake gear lever so that you can adapt it to your personal needs and preferences at any time.
