Through our custom install process, PRECISION 3 can be installed on a wide variety of crank arms. We’ll work with you to determine the best fit for your bike frame. Once you place your order, we get in touch with the shipping logistics. You’ll then send us your left crank arm, we install a PRECISION 3 Powermeter on it, and we ship it back to you.

Be warned: Failure after one year: Cadence readings but no power

Factory installed left hand crank Precision 3 power meter installed in January 2023.

February 2024: after 3 months of winter hibernation, I updated the firmware through the app and this coincided with the problem. I was getting cadence readings but no power data. I was unable to perform a Zero Offset through the app (Error message on app) and not able to calibrate via the Wahoo head unit either.

Battery 100%, battery contacts all good, followed all the 4iiii support advice, including a factory reset, but still no resolution. The 4iiii support service wasn't particularly informative either, even sending me photos and instructions that were three years out of date.

They finally said it's covered under warranty, so back it will go. This is the second 4iiii warranty job I've had to do in two (the battery contacts on an older unit broke).

When they work well, these power meters are excellent and good value for money. But they do seem to be prone to significant faults.

Will update this review in a few months after they fix the unit.
