FC-R9100 Crank The FC-R9100 enables optimum power transmission. This is achieved by its wider HOLLOWTECH II arm and a reinforced outer chainring on its unique four-arm asymmetric spider construction. The new R9100 cranks meet the highest standards in terms of stiffness and lightness.
Powermeter The SHIMANO-R9170 power meter: the essential performance tool for all cyclists who want to develop their true potential. By collecting accurate and reliable real-time performance data, you can monitor and evaluate every detail of your journey. You can use this insightful information to achieve top results in training or racing. Performance meters are one of the fastest spreading technologies in cycling today. After only a few years, they have become an affordable training aid for amateur racing cyclists and enthusiastic recreational cyclists, instead of being reserved for professionals only. The new power meter scores with a reliable electrical system including strain gages developed in-house. Fluctuating operating conditions - the system is waterproof - are automatically compensated by software. The system starts quickly, the response is direct. The data connection to the computer is possible via Bluetooth LE and ANT+. Firmware updates are also carried out wirelessly. The integrated lithium-ion rechargeable battery (more than 300 h driving time) is rechargeable. Replacing the chainrings does not affect the power meter. In riding mode there is a generous distance to the frame and Shimano Direct Mount brakes.
Dura-Ace R9100 The new Dura Ace from Shimano is the answer to the question posed by many professionals and ambitious amateurs as to whether and how the current already immensely high level of performance could be further improved. 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.
