Your Crank, our Power Meter

Installation
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.
Indoor Training
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, 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!
