Gold Standard In Accuracy
4iiii powermeters have had their gold-standard +/- 1% accuracy independently verified by leading scientists at the Locomotion Lab at the University of Colorado. This lets you plan your training, pacing, and racing with confidence, knowing that your equipment is measuring your true power output.
Dual-Channel ANT+ & Bluetooth Smart
4iiii powermeters communicate their measurements over both the widely-used ANT+ and Bluetooth Smart radio standards, letting you read and record your power numbers on an enormous catalog of headunits, sportswatches, smartphones, and computers.
3D Power Measurement
When you put force through your pedals or crank, it doesn't just bend the crank - it twists and flexes in all 3 dimensions. 4iiii's patented 3D power measurement system measures this multidimensional strain, so you can be confident that your unique pedal stroke is still measured accurately no matter your riding conditions.
