HOW DOES IT WORK?
A Ride-Ready PRECISION 3 pod is already preinstalled on a brand-new Shimano crank arm at our factory.  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.

IN THE BOX
Once your ride-ready PRECISION 3 Powermeter arrives, it just needs to be installed on your bike using the standard Shimano crank installation process. 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.

INDOORS
If the weather or climate make riding outdoors tough, your 4iiii power meter 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!

BATTERY LIFE
With up to 800 hours of battery life, you won't have to worry about changing your battery for years to come.

LIGHT WEIGHT
At only 9 grams the Precision 3 Powermeter weighs about the same as a sip from your water bottle. 

ULTRA LOW PROFILE
With an ultra low profile design, the PRECISION 3 is compatible with more bike frames than ever before.

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.
