4iiii Precision 2.0 Power Meter - Ultegra R8000 - 175mm

Training with power is a sure-fire way to ride faster and achieve podium performance. Whereas before, power meters were the reserve of the elite, thanks to the new 4iiii Precision 2.0 3D, power training is more accessible than ever. Unlike other larger units, this power meter only weighs 9 grams. Fitting so perfectly inside a regular Ultegra 8000 crank arm, you'll hardly notice it's there. By measuring your power output with +/- 1% accuracy, via the three-axis strain gauge, the 4iiii Precision 2.0 3D allows you to train with more consistency and, ultimately, achieve much better results. With an easily replaceable 2032 button cell battery, this power meter delivers over 100 hours of driving and, like a rechargeable battery, can easily be checked for life using the dedicated 4iiii companion app. Fortunately, the 4iiii Precision 2.0 3D is compatible with most ANT + and Bluetooth enabled devices. So no matter what computer, training device or apps you use, you won't have to worry about the integration between your new power meter and your current setup.
