INPEAK Powercrank-E Single Shimano GRX FC-RX810 / FC-RX820
The Polish manufacturer Inpeak offers you an inexpensive single-sided power meter with the highest possible measuring accuracy and state-of-the-art features. The power meter is mounted on an original left-hand Shimano GRX crank arm. All you have to do is replace your existing left crank arm and connect the power meter to your bike computer. The tiny measuring unit weighs just 10 grams. Thanks to the permanently installed lithium-polymer battery, no battery change is necessary and the battery can be conveniently charged using the magnetic USB charging plug included in the scope of delivery. Data is transmitted via ANT+ or Bluetooth. In addition to receiving a notification via an ANT+-compatible bike computer when the battery is below 10% of its life span, you can check the exact battery level at any time via the Inpeak smartphone app. In addition, LED lights on the power meter indicate a low charge level and information during the charging process. You can also calibrate and update your Inpeak power meter via the app.
The measuring unit is IP67-protected against water ingress, even in extreme weather conditions. In a range from -5°C to +50°C, the automatic temperature compensation ensures precise and accurate values with a maximum measurement deviation of +-2%. In addition to pedalling power, the power meter also measures your cadence, pedal smoothness and torque effectiveness. With the help of acceleration sensors and special algorithms, the power meter can also minimize the effects on the measured values of strong vibrations during off-road use or in poor road conditions.
All Inpeak products are developed, produced and assembled exclusively in the EU.
