Period of the day
We recommend testing very early in the morning before the wind starts to pick up or traffic begins to develop.
The chosen location must allow the athlete to accomplish multiple passes securely in both directions along a section of mostly flat and windless and road. Notio will process the data on roads with soft curves with a max gradient of 2%.
We recommend you ride at speeds close to Threshold pace. It is important not to stop entirely and be as constant as possible with speed while performing.
The greater the distance covered, the better are the results. The standard protocol recommends consisting of 3km out and 3km back. This length allows us to collect as much data as possible to obtain more consistent and accurate results. However, we are aware that not everyone has the same geographical reality. The most important is finding the longest and safest route possible over a distance of at least 1.6 km and seeing what the data allows you to do. With less, the data risk to be more variable (depending on the environmental conditions).
How to record an Aero Test
The most efficient way to record an Aero Test (calibration run) is from the App (Aero Test tool) or the Garmin. For both methods, you have to start recording before pedalling. On the way back, it is essential to stop recording the test where you began it. Our algorithm will automatically remove the acceleration from the start, the u-turn, and the deceleration at the end. That way, we can analyze identical separate sections to calculate the calibration factor and the CdA.
When do I need to calibrate my Notio?
It's crucial to recalibrate the Notio each time you remount/adjust the Notio and significantly if you've changed the Notio position, changed the rider position/fit, or if you've installed it with a new rider/bike. In brief, for every change that can affect the wind speed capture in the pitot tube, you must recalibrate the Notio. You don't need to recalibrate in between changes like helmets, wheels, clothing, or bottles.
