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 new Dura Ace front derailleur comes with a fundamental design change, several options for cable routing and integrated tension adjustment. The low-profile design provides a slim appearance while improving the ability to withstand damage from falls. The groupless left Shimano BL-RS600 brake lever is suitable for hydraulic disc brakes on racing bikes.
Wide Link The wide pivot link design boosts strength and rigidity. Especially for DURA-ACE, SHIMANO ULTEGRA and SHIMANO 105, the inner link as well as the right link is widened to add more rigidity. Flex is suppressed, creating sharp, precise shifts that are faster and smoother, even from low to high gears while off the saddle.
