3D Strain Gauge Technology
Not everyone has a perfect pedal stroke. 4iiii is the only crank-based power meter to use 3 strain gauges to measure all forces in your pedal stroke. Our patented 3D Strain Gauge design has been 3rd party tested to +/- 1% accuracy providing you with data that you can rely on to help you reach your fullest potential.
3 Year Warranty
A lot can happen in 3 years. You probably won’t need to use it, but it’s reassuring to know that all 4iiii Powermeters are backed by an industry leading 3-year warranty.
Ride Ready or Factory Install
Add power to your current crankset or purchase a new crank with our powermeter pre-installed. With our Factory Install option, you send us your crank, we install power on it and send it back to you in less than 2 weeks. We offer Factory Installs on a wide variety of cranks including SRAM, Cannondale and Campagnolo. Our Ride Ready offerings include a variety of Shimano left-sided and dual-sided cranksets that come with a 4iiii Power Meter pre-installed and ready to ride. Both options come with our standard 3 year warranty. Not sure what works best for you? Let us help you choose.
