4iiii PRECISION 2 Shimano GRX RX810 Power Meter. Introducing the all new 4iiii PRECISION Shimano GRX RX810 Power Meter. 4iiii has combined their patent pending 3-D tri-axial strain gauge technology, measured at +/- 1.0% accuracy, with Shimano's best of breed GRX RX810 groupset. The result is one of the lightest, most affordable and most accurate direct force power meters available. The PRECISION determines your total power based on the force that is generated by your left leg.
This left-only design allows for a power meter that is lightweight and easy to install. Specifically, the power meter adds only 9 grams to your crank arm and is installed in about 10 minutes.
In addition, the PRECISION is compatible with both ANT+ and Bluetooth SMART devices. The 4iiii PRECISION is one of the most affordable direct force power meters available.
The PRECISION is accurate to within +/- 1%. This compares to average accuracy of +/- 1.5-2% for most other power meters. Just swap it out for your current left-side crank arm and you're ready to ride! In addition to ANT+, the PRECISION also transmits data via the Bluetooth SMART wireless protocol. The 4iiii power meter is compatible with all Shimano GRX cranksets including GRX RX600.
