4iiii PRECISION 3 Power Meter: Details // Data // Review

4iiii have been in the power meter game for many years now and earlier this year (2022) they released their third generation of their PRECISION cycling power meter. What should have built on a relatively strong offering of the PRECISION 2 has been a rocky ride to date. This video covers the details of the PRECISION 3, my extensive testing, and my take on where things are at with this power meter.
