4iiii INNOVATIONS PRECISION 

I have been patiently waiting to demo the 4iiii Innovations Precision power meter. I have used the Viiiiva heart monitor strap for years and was ready to use the Duo for power, cadence and heart rate during my Fall training. The Precision power meter is battery powered and I was able to demo the Left crank FSA SL-K factory install. The 3-D power technology measures power through a tri-axial on the left crank arm. The data and accuracy is superior and is the most accurate that I can recall to date at +/- 1% error margin. The cycling data is accurate and consistent at all times for both power and cadence readings. The Precision install is lightweight on the FSA carbon crank (mere 9 grams), compact and durable.  The initial set up, pairing with devices and maintenance is incredibly simple. Precision is compatible with all Ant+, Bluetooth technology and smartphones for the very user-friendly 4iiii App experience. The system uses a Coin (2032) operated battery and has approximately 100 hours of riding time and to make things even easier/longer, additional coin battery was included with my purchase. The Precision was affordably priced at $399 for the factory left install. The 4iiii Precision has impressive technology, simple to install and set up for superior accuracy and cycling dynamics that will give you all the data you need to train harder, smarter and improve your performance.
