How do you define success? Whether you are fighting for a Kona slot, spending countless hours on the indoor trainer or striving for a personal best; one thing we know, success takes time.
With up to 800 hours of battery life, +/-1% accuracy and backed by our legendary 3-year warranty, the PRECISION 3 Powermeter will be your trusted training tool for years to come.
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.
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.
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.
If the weather or climate make riding outdoors tough, your 4iiii PRECISION 3 powermeter 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!
