The 4iiii Precision PRO Wattmeter is suitable for road riders who use the new Shimano Ultegra R8100 12-speed groupset and want to enjoy the benefits of power measurement without limitations. This package includes cranks with power meters already installed on both cranks.

  • Accuracy: 99%
  • Battery life: approx. 150-200 hours depending on 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
  • Compatible with ANT+ and Bluetooth 4.0 devices
The measurement is independent of the installed converters because it takes place on the crank. The chainrings can therefore be replaced with a different number of teeth or oval without the need for recalibration at the manufacturer.
