Instructions of 4iiii Precision Powermeter

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.


If the weather or climate make riding outdoors tough, your 4iiii power meter can be used with all popular indoor-training apps, such as Zwift, TrainerRoad, Wahoo SYSTM, Rouvy, and more. Simply use your favourite app’s connection procedure over ANT+ or Bluetooth Smart, put your bike on a trainer, and get riding!
