They are affordable and easy to install. The one consideration is they only measure left leg power compared to some other power meters that measure power from both legs (those version usually cost more however). CompatibilityCrankset: The 4iiii power meter is compatible with all Shimano GRX cranksets including GRX RX600.Check Frame Clearance: Crank-arm based power meters attach a sensor on the inside of the left crank arm. On some bikes, there is not enough room between the left crank arm and the chainstay for the sensor to clear the frame. Therefore, you should make sure you have at least 8 mm of clearance for the PRECISION 3+. Also, make sure that you don't have a bottom bracket mounted rear brake (used on some aero and TT bikes). The important area to measure is right in the middle of the crank arm. Please refer to the image below.If you find that your clearance is close but not quite sufficient, what many people will do is simply install a 1 or 2 mm bottom bracket spacer (between the left crank arm and the frame). This should provide you with the clearance you need.In the Box4iiii PRECISION Shimano GRX RX810 Power MeterCR2032 coin cell battery SpecsName4iiii PRECISION 3+ GRX RX810Bike TypeGravelLocation of Power MeasurementCrank ArmLeft or Both Legs MeasuredLeft onlyIndependent Left/Right MeasurementNoInstallationEasierCrank Arm MaterialAluminumCommunication ProtocolANT+ and Bluetooth SMARTClaimed Accuracy+/- 1.0%Automatic Temp.
