- “It’s amazing to have the opportunity to work with a Canadian brand like 4iiii. Their innovative data tools have helped me develop as an athlete, and the new dual-sided PRECISION 3+ PRO Powermeter is no exception. It allows me to perfectly pace my training whether it’s a long endurance outing or a short and punchy interval day. It has been my greatest navigator to track and monitor every detail of my progress.”

FAQs

-
How do I upgrade to a dual PRECISION 3+ PRO?
-
If you currently have a PRECISION 3 Powermeter (without Find My), you are required to include it with your drive-side crank for installation. Your current pod needs to be upgraded to PRECISION 3+ to ensure compatibility with the drive-side power meter.
If you currently have a PRECISION 3+ Powermeter you only need to send us your drive-side crank for installation. Learn More.

What’s new with PRECISION 3+ PRO?
-
In addition to offering all the same features at the single-sided version, the PRECISION 3+ PRO will allow you to view advanced metrics like left/right balance, pedal smoothness, torque effectiveness, and thereby providing you with the most accurate power numbers for training and racing. The decrease in expected battery life from 800-hrs (single-sided power) to 500-hrs with the dual-sided PRECISION 3+ PRO is simply a reflection of the added functions required by the paired power meters.
