4iiii PRECISION Shimano GRX RX810 Right Side Power Meter

The 4iiii PRECISION Shimano GRX RX810 Right Side Power Meter is perfect for those that have a 4iiii Shimano GRX left side crank arm power meter and want to upgrade to a dual-sided crankset. With power sensors on both the left and right crank arms, you can measure and record power from both legs! Or, some bike frames cannot fit a left side power meter due to clearance issues with the chainstay. In these situations, this 4iiii right side power meter is a perfect solution. It allows you to quickly and easily add power to the right side of your crankset where clearance and compatibility issues don’t exist.

The 4iiii GRX RX810 Right Side Power Meter uses patent pending 3-D tri-axial strain gauge technology, which is accurate +/- 1.0%. It’s also super lightweight (added weight of about 10 grams) and comes with a full 3-year warranty. 4iiii power meters are compatible with both ANT+ and Bluetooth SMART devices. This means you can use it with your favorite bicycle computer, watch or smart phone.
