Used to pace attacks up the Alpe D’Huez in the Tour de France and to hammer on the Queen K during the Ironman World Championships, the PRECISION Powermeter delivers accuracy and reliability when you need it most. Through our patented 3D Strain Gauge technology, you can be assured that the data you depend on will lead you to your own Yellow Jersey. Packaged into a durable lightweight design and compatible with ANT+ and Bluetooth Smart headunits, PRECISION will help you train harder and smarter.


How Does It Work?

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

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

In The Box

After a factory installation, your crank arm will be returned to you with a PRECISION Powermeter pod attached and ready to ride. Reinstall the crank arm back onto your bike, connect a headunit or computer, and you can start riding with power!

Warranty & Durability

Ridden through rain storms at Strade Bianche, mud filled cross country mountain bike races, and even tested amidst the salt spray of the ocean on Oracle Team USA’s America’s Cup competitors, you can be assured that your 4iiii power meter will be as tough as you are and is backed with an industry leading 3-year warranty. All 4iiii power meters are IPX7-rated for water immersion up to one meter and backed with an industry-leading 3-year warranty.

  1. 4iiii Warranty Policy


  • Light Weight

    At only 9 grams the Precision 3 Powermeter weighs about the same as a sip from your water bottle. Our goal is to help you get faster, not to slow you down.

  • Battery Life

    With over 100 hours of battery life, you won’t have to worry about frequent changes.

  • Accuracy in 3D

    Not everyone has the perfect pedal stroke. With +/- 1% accuracy, 4iiii is the only crank-based power meter to use 3 strain gauges to measure all forces in your pedal stroke.

  • 3 Year Warranty

    A lot can happen in 3 years. You probably won’t need to use it, but it’s reassuring to know that all 4iiii power meters are backed by an industry leading 3-year warranty.
