4iiii Precision 2 Factory Install Power Meter
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 industry leading 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 help 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.
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.
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 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.
In The Box
After a factory installation, your crank 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!
Tip: If you're unsure, a bike shop would be happy to aid you in removing your crank or crankset and reinstalling once your 4iiii Powermeter is installed.
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 Powermeter will be as tough as you are and is backed with an industry leading 3-year warranty. All 4iiii Powermeters are IPX7-rated for water immersion up to one meter and backed with an industry-leading 3-year warranty.
If the weather or climate make riding outdoors tough, your 4iiii Precision powermeter can be used with all popular indoor-training apps, such as Zwift, TrainerRoad, TheSufferFest, 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!
3D Power Measurement
When you put force through your pedals or crank, it doesn't just bend the crank - it twists and flexes in all 3 dimensions. 4iiii's patented 3D power measurement system measures this multidimensional strain, so you can be confident that your unique pedal stroke is still measured accurately no matter your riding conditions.
Industry Leading Accuracy
Our +/- 1% accuracy isn’t just a claim, it’s been third party tested and validated by leading scientists and the Locomotion Lab at the University of Colorado. You can plan your training, pacing, and racing with confidence knowing that your data is always going to be consistent. Don’t limit your potential with unreliable data. Want to learn more?

Dual-Channel ANT+ & Bluetooth Smart
4iiii Powermeters communicate their measurements over both the widely-used ANT+ and Bluetooth Smart radio standards, letting you read and record your power numbers on an enormous catalog of headunits, sportswatches, smartphones, and computers.
3 Year Warranty
4iiii Powermeters are waterproof, durable, and designed to be accurate and precise even in the harshest conditions. Because of this, we are happy to offer an industry-leading 3-year warranty.
