How It Works?

The PRECISION 3+ PRO Powermeter is more than just a dual-sided power meter—it serves as a dependable training partner while offering added peace of mind. During rides, it transmits key data such as power output, cadence, cycling metrics, and calories to your preferred head unit, and when not in use, its Apple Find My integration allows you to track its location on a map via the Find My app on your iPhone, iPad, Mac, or through the Find Items app on an Apple Watch.

IN THE BOX

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.
