Real World Use

Avio PowerSense is there to help amateur riders reach the very best of their abilities from the grass-roots up with professional equipment.


Active Temperature Compensation

The consistency of measurement is the most important feature of a power meter. Using industry standards with Active Temperature Compensation, Avio PowerSense can now use this information as an automatic process to ensure accurate readings no matter the environmental conditions.


Accuracy Level

Each Avio PowerSense is individually calibrated before preparation of delivery to ensure a +/- 2% accuracy level, which is standard accuracy for non-scientific power meters. Individual calibration means that you can trust the data which has been produced by our systems, as it’s an actual measurement and not an estimation.
