| ANIMATION OF FIELD TRIAL RECORDING |
Below, a animation of the recordings of an Active-Spoke test run that shows the Active-Spoke effect.
The chart plots SPEED vs SLOPE. While we're not suggesting every test run was like this, this was the
first run in a series of experiments and highlights the Active-Spoke effect.
You will note that when the slope changes dramatically (rapid horizontal movement), the BLUE (i.e.
Active-Spoke ride) trace increases in speed. When there is minimal change in slope, speed
differentials stabilize.
BLUE = Active-Spoke wheel RED = Equivalent wheel without Active-Spoke
Method Overview - Used an SRM PRO recorder @ 0.5sec sample rate and a Garmin unit for altitude.. As far as
possible, all external factors where kept constant other than the Active-Spoke wheel: a paired run completed on the
same course, same rider, same bike, same contant wattage average (330w) over 4 miles, within 30mins of each other;
same wheel, tire, tube EXCEPT- one with Active-Spoke (BLUE) and one without Active-Spoke (RED). While this run
showed ~10sec / mile in favor of Active-Spoke, this is not typical... however, we used in this example as it highlights
the effect in the chart
