How Does It Work?

A ride ready PRECISION 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.

Important: You need to use the frame clearance guides to ensure there is space between your crank and frame for the PRECISION pods.

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.

All 4iiii power meters are IPX7-rated for water immersion up to one meter and backed with an industry-leading 3-year warranty.
