The Factory Install PRECISION gives you the flexibility of having a 4iiii Powermeter installed onto a crank you supply. To learn more about this process see below.

Installed Locally in the UK.

Through our custom install process, PRECISION can be installed on a variety of crank arms. We’ll work with you to determine the best fit for your bike frame. Once you place your order, you’ll then send us your left crank arm, we install a PRECISION left-side powermeter on it, and we ship it back to you.

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

Clearance Check Guide

Frame/Bike Compatibility
Because 4iiii PRECISION powermeters are mounted on the inside of your crank, there needs to be enough space between your crank and the frame for the pod to fit. Print and use the clearance guides below to check your frame.
