4iiii Innovations Precision 3+ Power Meter RX810 GRX NDS

The Precision 3+ Power Meter is a lightweight crank-based power measurement system designed for cyclists who want accurate performance data. While riding, it transmits watts, cadence, and calories to your head unit of choice via ANT+ and Bluetooth connectivity. When not in use, the power meter integrates with Apple Find My, allowing you to locate it on an iPhone, iPad, Mac, or Apple Watch. This dual functionality combines performance tracking with device recovery capabilities. The power meter delivers industry-leading accuracy at ±1% and operates for up to 800 hours on a single CR2032 coin cell battery. Its waterproof design and low-profile construction make it suitable for all riding conditions, while the 9g weight keeps it lightweight.
