Whether you're training for an event or wanting to beat your previous goals, the Precision Pro is the ultimate component for the job. This dual-sided model (comes with both crank arms, left crank arm has strain gauges built-in) provides readings with an accuracy of within +/- 1% and can be used with your Shimano Ultegra R8000 drivetrain. 4iiii has built on what it learned when producing their left-side model (exceptional accuracy, lightweight design, ANT+ and Bluetooth compatibility, 3D power meter technology), by developing the technology even further for increased precision of the readings. This model is assembled within Shimano's stunning Ultegra R8000 crankset and measures the individual power output of each leg. ANT+ and Bluetooth connectivity allow you to wirelessly connect to it using your smartphone and a wide variety of devices. Accurate and consistent, its smartphone app also gives you access to the rider compensation scale and other useful features such as a battery status indicator. The app also allows you to enjoy over-the-air upgrade capabilities such as adding new features and updates. What's most impressive is its battery life lasts 100+ hours on a 2032 coin cell battery, so you'll benefit from precise and reliable data for longer than ever before. Lightweight and compact, this is a perfect choice of upgrade for riders who want to take their road cycling to the next level.
