Why We Love It
How do you define success? Whether you are fighting for a Kona slot, spending countless hours on the indoor trainer or striving for a personal best; one thing we know, success takes time. With an industry-leading 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.
About This Item
  • 3D Power Measurement - 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
  • Ultra Low Profile - With an ultra low profile design, the PRECISION 3 is compatible with more bike frames than ever before
  • Indicator Light - At a glance, you can now see when your power meter has turned on, performed a successful Zero-offset, or has a low battery
  • Waterproof - Based in the foothills of the Canadian Rockies, we were tired of training tools not 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
  • Dual-Channel ANT+ & Bluetooth Smart - Get the same numbers training inside and outside. The PRECISION 3 Powermeter is both ANT+ and BLE compatible so you can use it on your preferred head unit and favorite indoor training app
  • 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
