4iiii Precision 3+ XT M8100 Left Hand Power Meter Crank

Our most powerful unit to date, compressed into a smaller, lighter package and featuring support for Apple Find My, the Precision 3+ Powermeter is a proven choice of pros and weekend warriors alike. Whether you’re fighting for a Kona qualification spot, logging countless hours on virtual riding platforms or looking to better your time up the local KOM segment, you want accurate and reliable tools to unlock your potential. With up to 800 hours of battery life, an automatic terrain selector, +/-1% accuracy and backed by our industry-leading 3-year warranty, the Precision 3+ Powermeter will be your trusted tool for years to come.

How Does It Work?

The Precision 3+ Powermeter is so much more than a power meter. It’s your training partner that offers peace of mind. While you are riding, your Precision 3+ Powermeter will transmit Watts, cadence, and calories to your head unit of choice. While the power meter is not in use, Find My is enabled and allows you to see its location on a map. You can add your power meter to the Find My app and locate it on an iPhone, iPad, Mac or using the Find Items app on an Apple Watch.

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 head unit or computer, and you can start riding with power. Connect to the Find My app with your iPhone or iPad to start tracking your power meter.

Features

Apple Find My: Offering the peace of mind in knowing where your power meter is.
Battery Life: With up to 800 hours of battery life, you won’t have to worry about changing your battery for years to come.
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.
Automatic Terrain Selector: Detects the terrain you’re riding on for more responsive cadence and power feedback/data. Ride the roads less traveled with confidence.
Ultra Low Profile: With an ultra low profile design, the Precision 3 is compatible with more bike frames than ever before.
Light Weight: At only 9g 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.
Waterproof: Designed to work in our tough environment. With an IPX7 waterproof rating you can be assured that your power meter can handle the toughest conditions.
3 Years 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.
