4iiii Ultegra 8000 PRECISION 3.0 Powermeter

This high-quality powermeter comes factory fitted into a Shimano Ultegra 8000 left-sided crank arm, making it perfect for road cyclists who want to take their training sessions up a level. With an ultra-precise +/- 1% accuracy and an impressively light 9g weight, this left sided power meter is all set for helping you reach your performance goals. Another highlight is its lightweight crank arm design that is optimised for maximum power-transfer efficiency without sacrificing stiffness. At 5.5mm high, this Precision 3.0 powermeter is compatible with almost every bike frame on the market. In addition, the indicator light will let you know when your power meter is on, performed a successful zero-offset, and is ready for its battery to be changed. One final highlight is that it boasts up to 800 hours of battery life from its long-lasting coin cell battery.

Shimano Ultegra 8000 Crank Arm

The Shimano Ultegra 8000 series is “pro-proven” as it is a direct trickle-down from the Dura-Ace groupset.

Advanced control in all conditions. Customisable for your racing style.

• 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.
• 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. Although, don’t expect to see that low battery indicator for a while!
• 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.
• ANT+ and Bluetooth: 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: A lot can happen in 3 years. You probably won’t need to use it, but it’s reassuring to know that all 4iiii Powermeters are backed by an industry leading 3-year warranty.
