How Does It Work?
A Ride-Ready PRECISION 3 pod is already preinstalled on a brand-new Shimano crank arm at our factory. The moment you order, our fulfillment team will get it on its way to you, and you should be able to ride with power as soon as it arrives. With up to 800 hours of battery life, +/-1% accuracy and backed by our legendary 3-year warranty, the PRECISION 3 Powermeter will be your trusted training tool for years to come.
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 headunit or computer, and you can start riding with power!
