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.

4iiii Precision Pro Ultegra R8000 Power Meter is rated 4.7 out of 5 by 3.
Rated 5 out of 5 by Pearsy from Quality product Fast delivery and easy installation and set up. Definitely recommend. Power figures track well with wahoo kickr
Date published: 2021-03-22
Rated 4 out of 5 by Splodge63 from Simple and effective Paired straight away with Garmin 820 and works faultlessly. Phone app shows battery levels - got 150 hrs on first set. Sometimes gives a “calibration error” But works anyway. Usually just calibrates fine and I don’t think it drifts much anyway. It’s bonded to Ultegra cranks which are of course bomb proof. Also allowed me to ditch cadence sensor as it supplies this as well.
Date published: 2020-05-18
Rated 5 out of 5 by Bonzo67 from Straightforward Straightforward to replace and set up. Close match to smart trainer numbers, allowing that this is more accurate at +/- 1% accuracy. Time will tell how long it lasts and stands up to use. Calibration is easy via the 4iiii app or via a head unit.

Worn chainring

When the chain rings have been worn out can they be replaced on the crank side?
Asked by: andrewmoore24
This is a the same as a normal R8000 chainset so the chainrings can be replaced.

Will this be compatible with a 105 R5800 drivetrain?

I am currently running a full 105 R5800 groupset, I am wondering if the R8000 crankset will especially be compatible with the R5800 FD.
