About the 4iiii PRECISION PRO Power Meter
The 4iiii PRECISION PRO power meter takes the original single-sided PRECISION to the next level with dual sided power. The PRECISION PRO locates one power sensor the left crank arm and another on the chainring. This dual sensor configuration allows you to measure total power as well as left and right leg power independently. In addition, this power meter uses its patent-pending 3D strain gauge technology to deliver industry-leading +/- 1.0% accuracy.
The PRO supports dual ANT+ and Bluetooth SMART wireless protocols. With ANT+, you can use the power meter with your favorite bicycle computer. Bluetooth SMART allows you to also connect using your smart phone or tablet. In addition, with Bluetooth, you can keep your power meter updated at all times with over-the-air firmware upgrades using the 4iiii app for iOS and Android devices.
And if you’re concerned about weight, you will be happy to know the PRO features a super lightweight design – adding only 25 grams of weight to your bike. This makes it one of the lightest power meters on the market!
The PRECISION PRO comes pre-installed on a Shimano DURA-ACE 9000 series crankset.
