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 GRX RX810 groupset. The result is one of the lightest, most affordable and most accurate direct force power meters available for gravel and adventure riders.

The 4iiii power meter measures left leg power and doubles this value to determine your total power. This left-only design allows for a power meter that is affordable, lightweight and easy to install. 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. This means you can use it with your favorite bicycle computer, watch or smart phone.
