  • Automatic Terrain Selector

    Automatic Terrain Selector

    The Automatic Terrain Selector was specifically developed to guarantee optimal performance and unwavering accuracy across any riding surface. It uses the accelerometer for exceptional battery life on smooth steady state cruising and automatically switches to the gyroscope on rough terrain, gravel or for the high rpm sprints. Ride the road less traveled with confidence.

  • Introduction

    3D Strain Gauge Technology

    Not everyone has a perfect pedal stroke. Forces on your crank change when seated, standing to get over a steep climb, or sprinting towards the finish line. As well, as you fatigue your own pedal stroke can change over the duration of your ride. To ensure that every force put into your crank is measured, our patented 3D strain gauge technology measures power by using the lateral bend, pull, and twist of your crank. This means that throughout your ride, your power numbers will reflect the changes to your pedal stroke no matter how you are riding.

    Industry Leading Accuracy

    +/- 1% accuracy has been third party tested and validated through The University of Boulder Colorado. See the report here.

    Cycling Metrics

    With the PRECISION 3+ PRO Powermeter you can get advanced cycling metrics like torque effectiveness and pedal smoothness to optimize your pedal stroke.

    Scale Factor

    Take your leg imbalance into account with a left only power meter by adjusting the scale factor using the 4iiii app.

  • Inside & Outside

    The Same Numbers Training Inside & Out

    All of our power meters are ANT+ and Bluetooth (BLE) compatible meaning that you can receive from your 4iiii power meter on your preferred ANT+ device or connect it to your laptop or tablet to use your power meter over BLE with your favorite indoor training app. This means that the power numbers that you see on Zwift or TrainerRoad will be consistent with the numbers that you see outside.

    Inside And Out

    Pair your smart trainer to ERG while using your power meter as the power output device.

    Broad Compatibility

    Bluetooth compatibility means your power meter will work with Zwift, TrainerRoad, Rouvy, SYSTM or any other of your favorite indoor training apps.

    Consistent Numbers Are Winning Numbers

    Don’t get caught off guard with different numbers when training inside vs outside.

  • Water Resistance

    The Only Thing You Need to Keep Dry is Your Socks

    Based in the foothills of the Canadian Rockies, we were tired of training tools not designed to work in our tough environment. We took things into our own hands and designed a product to work in our conditions. With an IPX7 waterproof rating you can be assured that your power meter can handle the toughest conditions. The only thing that you’ll have to worry about keeping dry is your socks.

  • Weight

    The Same Weight as a Sip of Water

    At only 9 grams for a left sided crank or 29 grams for a dual system, 4iiii makes the lightest power meter on the market. Our goal is to help you get faster, not to slow you down.

  • Temperature Compensation

    Active Temperature Compensation

    As the temperature changes throughout your ride, it can affect the consistency of your power numbers. That is why we use active temperature compensation that continually adjusts to the conditions to ensure that no matter what nature throws your way, your power numbers will be consistent.

  • 3 Year Warranty

    3-Year Warranty

    A lot can happen in 3 years so we wanted to make sure we created a product that is with you for every win, every epic ride, and even the recovery rides to your local cafe. 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.
