HOW DOES IT WORK?

The PRECISION PRO+ Powermeter is more than just a dual power meter—it's an essential training companion that also provides security. During your ride, it transmits watts, cadence, cycling metrics, and calories to your preferred head unit. When not in use, the Find My feature activates, enabling you to track its location via the Find My app on iPhone, iPad, Mac, or the Find Items app on an Apple Watch. This integration ensures you can always locate your power meter with ease.

IN THE BOX

When your PRECISION PRO+ Powermeter arrives, simply install it on your bike following the standard Shimano crank installation procedure. Pair it with a head unit or bike computer to begin measuring power immediately. Additionally, connect your device to the Find My app on your iPhone or iPad to enable tracking of your power meter.
