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 make it right to the top. As it collects reliable power data in real time, the crank helps you monitor and analyse every single detail of your ride to achieve top results in training and competitions. The extravagant and elegant design of the Dura Ace crank arms, the tidy integration of the power meter and the low weight are just some of the highs for performance-oriented road cyclists.
In contrast to heart rate measurement, power measurement in watts delivers a more objective picture of your performance during your ride. Whereas it can take up to 2 minutes to reach the heart rate zone, a power meter gives you immediate feedback within seconds. Besides, your power is not affected by external factors like weather, fatigue or health problems. This especially proves advantageous for short and intensive interval trainings.
The compact SHIMANO Dura Ace FC-R9100-P power meter unit is fitted behind the chainrings for a clean look. Besides, both crank arms come with integrated, highly precise strain gauges that allow you to measure left and right power separately and thus detect any muscular difference. The special, integrated design allows for a fast and easy replacement of chainrings without affecting the power meter’s accuracy. The Shimano meter pairs with the E-Tube app via Bluetooth for easy system checks and firmware updates. Apart from 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, item no.: 2263925). The battery is charged with a magnetic cable.
