4iiii Precision GRX RX810 Power Meter Left Only Crank Arm

4iiii’s Left Crank Arm Precision GRX RX810 Power Meter takes a Shimano crank and adds a nine gram Precision Pod to enable accurate power measurement for more effective training or racing. The Pod is accurate to +/- 1% according to the independent Locomotion Lab at the University of Colorado, and their 3D power measurement system allows for each individual’s pedal stroke as it takes into account three-dimensional strain, making it one of the most precise power meters available.

As it communicates using both ANT+ and Bluetooth Smart it is compatible with virtually all head units and sports watches. The unit is fully waterproof, making it ideal for the tough off-road conditions that Shimano’s GRX gravel components were designed to work in and the easily replaceable CR2032 battery should give over 100 hours of riding.
