ABOUT THE 4IIII PRECISION POWER METER FOR SHIMANO ULTEGRA 8000
Used by the World Pro Etixx-Quick-Step Team, the 4iiii PRECISION Power Meter for Shimano Ultegra 8000 is the lightest, most affordable direct force power meter available. The added weight of the 4iiii PRECISION is only 9 grams and it is accurate to within +/- 1%.
The 4iiii PRECISION is a left-only crank arm-based power meter and replaces your current left side crank arm. The 4iiii takes the power that is generated by your left leg and doubles it in order to determine your total power output.
In addition to being affordable, lightweight and highly accurate, the 4iiii PRECISION measures precise cadence data, has 3D power meter technology capable of measuring tri-axial strain and is compatible with both ANT+ and Bluetooth SMART devices.
WHY 4IIII PRECISION
High Level of Accuracy
The PRECISION is accurate to within +/- 1%. This compares to average accuracy of +/- 1.5-2% for most other power meters.
Lightest Power Meter
At only 9 grams (the weight of the 4iiii pod), the PRECISION is the lightest power meter you can buy!
Easy to Install
Because the PRECISION is a left-side crank arm power meter, installation is a breeze. Just swap it out for your current left-side crank arm and you’re ready to ride! Installation takes minutes…not hours.
Bluetooth SMART
In addition to ANT+, the PRECISION also transmits data via the Bluetooth SMART wireless protocol. This means it is compatible with any bicycle computer, smart phone or tablet using these protocols.
