It’s your training partner that offers peace of mind. While you are riding, your PRECISION 3+ Powermeter will transmit watts, cadence, 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. In the Box-Once your ride-ready PRECISION 3+ 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.
