4iiii Innovations, the leader in power-driven cycling performance, has announced today its latest firmware update to its PRECISION 3 Powermeter. 

PRECISION 3 retains its extremely low profile, 800-hour battery life, and stellar accuracy, but adds Gyroscope and more responsive cadence and power output. 4iiii has taken a new look at the cadence algorithm, the sensors used, and when they are used based on innovative new development processes. 

Key Features of the 1.2.0 Realtime Terrain Auto-Optimizing Firmware update: ● Specifically developed to guarantee optimal performance and unwavering accuracy across any riding surface. 

● Uses the accelerometer for exceptional battery life on smooth steady state cruising and automatically switches to the gyroscope on rough terrain, gravel or for the high RPM sprints. 

● Improved cadence reliability for buttery smooth power measurement. ● Instantaneous startup and transitional responsiveness for those sprinting from 0 to hero, up to 220 rpm! 

● Industry-dominating battery life on a coin cell. 

“We’re committed to disrupting every part of the cycling experience we touch,” says Phil White, President and CEO of 4iiii. “With this update, we’ll be able to integrate features powered by our patented 3D power meter system and machine learning without decreasing long battery life and the precision for which 4iiii is known.

In addition to these features, we also see this firmware as a way to start to treat power meters as tech platforms for cyclists. Innovations like this will allow us to further unlock a rider’s potential with simplified training tools.“ 

With two patents pending for new technologies developed, the PRECISION 3 firmware update 1.2.0 will be available for all PRECISION 3 owners starting March 30, 2023, via the 4iiii app. More details on the specifics of the firmware, testing processes, and future 

innovations will be hosted on’s blog page. 4iiii power meters are available at as well as select online retailers.
