How Does It Work?
A ride ready PRECISION pod is already preinstalled on a brand-new Shimano crank 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.
In The Box
Once your ride-ready PRECISION 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!
Tip: If you’re unsure, a bike shop would be happy to aid you in the installation process.
