Shimano Dura Ace R 9100 Power Meter

If you want to develop your true potential as a cyclist, the SHIMANO Dura Ace FC-R9100-P crankset with integrated power meter is your essential performance tool to get to the top. Because it collects reliable power data in real time, the crank helps you monitor and analyze every single detail of your ride for the best results in training and racing. The extravagant and elegant design of Dura Ace cranks, neat integration of the power meter, and low weight are just a few of the highs for performance-oriented road cyclists.

Unlike measuring heart rate, measuring power in watts provides a more objective picture of performance while riding. Considering that it can take up to 2 minutes to reach the heart rate zone, a power meter gives you an immediate feedback within seconds. In addition, your power is not affected by external factors such as weather conditions, fatigue, or health problems. This is especially beneficial for short, intensive interval training.

The compact power meter SHIMANO Dura Ace FC-R9100-P is mounted behind the chainrings for a clean look. In addition, both cranks have integrated high-precision strain gauges that allow left and right power to be measured separately and thus detect any muscle differences. The special integrated design allows for quick and easy replacement of the crowns without affecting the accuracy of the power meter. The meter Shimano pairs with the E-Tube app via Bluetooth for easy system checks and firmware updates. In addition to Bluetooth, the power meter features ANT+ to ensure compatibility with a wide range of third-party bike computers and GPS devices (e.g., Garmin Edge 1030, part number: 2263925). The battery is charged with a magnetic cable.
