Sections and Laps
For example, for an out & back test there are two sections per lap (the out and the back). Whereas, a circuit course such as a velodrome a single section is equivalent to a lap since there is no turn around.
The distance in millimeters traveled by one revolution of the wheel. The quantity is used in the on-board calculations within the AeroPro. To reduce error averaging multiple wheel rollout tests is suggested. Error in wheel circumference is corrected in any outdoor protocol, absolute accuracy is only required for indoor testing such as a velodrome.
A converged CdA value is the goal of an aero test; a good indicator of this is observing consistent values across multiple laps within a session.
Wheel Rollout Test
The test performed to measure wheel circumference.
- Mark or align with a feature (i.e. logo or valve stem) the point on the tire in contact with the ground;
- Roll the bike forward 1 or more whole revolutions of the wheel;
- Measure the distance from the starting to end location of the wheel contact point;
- Divide by the number of revolutions performed;
Example: If 5 revolutions measures a rollout of 10.48 meters the average wheel circumference is 10,480mm/5 = 2096mm
