The 4iiii R8000 power meter is a lightweight design and adds only 9 grams to the standard Shimano crank. This makes it the lightest power meter on the market. The power meter has a very accurate measurement with only +/-1% deviation. The 4iiii R8000 power meter determines your total power, but is based on the power that’s generated by your left leg. 

The 4iiii R8000 power meter can be installed easily, and the configuration is done with 4iiii Device Configuration. This app is available for Android and iOS. With this app, you can also check the state of the CR2032 button cell battery. This battery lasts for more than 100 hours of riding. The power meter unit weighs only 9 grams and the measurement deviation is only +/- 1%.


Ridden by the pros, PRECISION PRO dual-side power meters deliver all the benefits of our left-side model (exceptional accuracy, lightweight design, ANT+ and Bluetooth compatibility, 3D power meter technology), plus a specific breakdown of left and right wattage. Perfect for those who need specific power output from each crank side, or anyone who simply wants the best power meter on the market. 

The PRECISION PRO Factory Install is installed on your existing crankset at our factory. 

Place your order, and we’ll be in touch to let you know how to send us your crank and when you can expect it back in your hands.
