Whether you're fighting for a qualifying spot in Kona, logging countless hours on virtual riding platforms or looking to improve your time in the local KOM segment, you want accurate and reliable tools to unlock your potential. With up to 800 hours of battery life, an automatic terrain selector, +/-1% accuracy and backed by our industry-leading 3-year warranty, the PRECISION 3+ Powermeter will be your trusted tool for years to come.

HOW IT WORKS.
The PRECISION 3+ Powermeter is so much more than a power meter. It is your training partner that gives you peace of mind. While cycling, your PRECISION 3+ Powermeter sends watts, cadence and calories to your navigation of choice. When the power meter is not in use, Find My is enabled and your power meter turns into an Apple Airtag. You can add your bike and view its location through the Apple FindMy app on your iOS device.
