The gold standard of accuracy.
The accuracy of the 4iiii power meters has been independently verified by leading scientists at the University of Colorado Locomotion Lab to within +/- 1%. So you can plan your training, pacing and racing with confidence, knowing that the device is measuring your true performance.
Dual channel ANT+ and Bluetooth Smart
4iiii power meters communicate their readings via the widely used ANT+ and Bluetooth Smart wireless standards, so you can read and record your power readings on a huge catalog of terminals, sports watches, smartphones and computers.
3D power measurement
When force is applied to the pedals or cranks, they don´t just bend, they twist and flex in all three dimensions. 4iiii´s patented 3D force measurement system measures this multi-dimensional stress, so you can be confident that every step is still measured accurately, regardless of riding conditions.
3-year warranty
4iiii power meters are waterproof, durable and designed to be accurate and precise even in the harshest conditions. That´s why they come with an industry-leading 3-year warranty.
