4iiii Precision Pro 3D DUAL cranks with wattmeter, 2x12, Shimano FC-R8100
Wattmeter 4iiii Precision PRO is suitable for road riders who use the new 12sp Shimano Ultegra R8100 set and want to enjoy the benefits of power measurement without limitation. This package includes cranks with power meters already installed on both cranks.
- Accuracy: 99%
- Battery life: approx. 150-200 hours depending on the ambient temperature
- Integrated accelerometer for measuring cadence (pace)
- Wireless firmware updates via Bluetooth
- Measured power range: 0-1999 W
- Range of measured cadence: 30-220 revolutions

The measurement is independent of the installed transducers, as it takes place on the crank. The converters can therefore be replaced with a different number of teeth or oval ones without the need for recalibration at the manufacturer.
