Delivering the same reliable and highly accurate power data you've come to expect from 4iiii, while providing the peace of mind that comes with knowing the location of your bike. With advanced metrics such as left/right balance, pedal smoothness and torque effectiveness, the PRECISION 3+ PRO Powermeter provides the data you need for training and racing. With up to 550 hours of battery life, an automatic terrain selector, +/-1% accuracy and backed by our industry-leading 3-year warranty, the PRECISION 3+ PRO Powermeter will be your trusted tool for years to come.

The PRECISION 3+ PRO Powermeter is so much more than a dual power meter. It's your training partner that offers peace of mind. While you are riding, your PRECISION 3+ PRO Powermeter will transmit watts, cadence, cycling metrics, and calories to your head unit of choice. While the power meter is not in use, Find My is enabled and allows you to see its location on a map. You can add your power meter to the Find My app and locate it on an iPhone, iPad, Mac or using the Find Items app on an Apple Watch.

Once your ride-ready PRECISION 3+ PRO Powermeter arrives, it just needs to be installed on your bike using the standard Shimano crank installation process. Connect a head unit or computer, and you can start riding with power. Connect to the Find My app with your iPhone or iPad to start tracking your power meter.
