HOW DOES IT WORK?
The PRECISION 3+ power meter is much more than just a power meter. It’s your training partner that gives you peace of mind. While you’re riding, your PRECISION 3+ power meter will transmit watts, cadence, and calories to the main unit of your choice. When the power meter isn’t in use, Find My is activated, allowing you to view its location on a map. You can add your power meter to the Find My app and locate it on an iPhone, iPad, or Mac, or using the Find Items app on an Apple Watch.
IN THE BOX
Once you receive your PRECISION 3+ power meter ready for mounting, simply install it on your bike by following the standard Shimano crankset installation process. Connect a head unit or computer, and you’re ready to start power cycling. Connect to the Find My app with your iPhone or iPad to start tracking your power meter.
