4iiii RX810 GRX NDS PRECISION 3.0 Powermeter

This ready to ride powermeter comes factory installed into a Shimano RX810 GRX left-sided crank arm, which makes it perfect for gravel adventure riders and road cyclists who want to push their training sessions to the limit for maximum performance gains. Showing off a design that boasts up to 800 hours of battery life, it uses a long lasting coin cell battery to survive the most demanding of training rides across rough, mixed terrain conditions. 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. Coming complete 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.

Shimano RX810 GRX Crank Arm

Shimano GRX, with its gravel-specific ergonomics, optimised gearing options, rugged reliability, and quiet and stable drivetrain, sets itself apart from the rest of the component world. It isn’t a reworked set of road components. It represents a ground up look at how cyclists want to explore their world. Shimano GRX helps you eliminate excuses, instead urging you to try that rough sidetrack or ride that little bit longer. It offers you the option to explore beyond.

Up To 800 Hour Battery Life

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

+/- 1% Accuracy

Everyone has a unique pedal stroke. 4iiii’s patented 3D strain gauge measures all forces to deliver precision accuracy.

9g Weight

4iiii has confirmed that it makes the lightest power meter on the market. The brand is committed to helping you get faster, one gram at a time.

Technologies:

  • 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.
