How does it work?
The PRECISION 3+ Powermeter is more than just a power meter. It’s your training companion that gives you peace of mind. As you ride, your PRECISION 3+ Powermeter will transmit watts, cadence, and calories to your go-to device. When your power meter is not in use, the Find My feature is active 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 your iPhone, iPad, Mac, or using the Find My app on Apple Watch.

In the box
Once you receive your PRECISION 3+ power meter ready to go, simply install it on your bike using the standard Shimano crankset installation procedure. Connect a reference device or computer and you can start pedaling with power. Connect to the Find My app with your iPhone or iPad to start tracking your power meter.

Warranty and Durability
Used in the pouring rain of Strade Bianche, during muddy cross-country mountain bike races, and even tested in the salty ocean spray of Oracle Team USA's America's Cup competitors, you can be confident that your 4iiii power meter will be as tough as you are and is backed by an industry-leading 3-year warranty. All 4iiii power meters are IPX7 rated for submersion in up to 1 meter of water and are backed by an industry-leading 3-year warranty.
