Aero Testing - How fast are we?

The Test
As an aerodynamic apparel company, it’s important that we are pursuing our commitment to delivering you speed. We visited the Silverstone Sports Engineering Hub to test our products and see how we performed against the top level competitors in the market.
In this article, we present our testing protocol, the testing data and a thorough conclusion on the accurate performance of our products.
Our Protocol
Our testing protocol has been constructed to provide authentic results and factual data. We discussed our process prior to the testing with the wind tunnel manager to ensure that all results would provide the information we required in a fair and level environment.
We conducted two test runs on a static mannequin. This was completed to ensure there were no abnormal movements during the testing. Our initial test was carried out using a regular cotton sock, while our run 2 test was carried out using our own Performance Watts Aero Socks.
Each test was performed at 40,45,50,55 & 60 kmph as this covered a wide range of realistic race speeds. 2 x 30 second runs for each speed were carried out for both mannequin and rider to ensure accurate data and provide an average of both tests as the final result.
How Accurate Are We?
We used a rider to perform our second tests. Although the mannequin provides an accurate testing result of how our material performs, we wanted to capture the movements of airflow around a moving leg at various angles in an everyday pedalling motion. This provides accurate data at every degree within the motion.
Most companies will test their material in a cylinder wind tunnel, this will provide data on how fast the said material is, however this is based on a cylinder and the results may not transfer when being tested on a leg, as we don’t have perfect cylinder shaped legs.
The static mannequin is 3d printed and is a more accurate leg shape compared to the cylinder test. However the natural movements in the pedalling motion differ to a static mannequin so it was important we gained results from both tests to ensure maximum accuracy.
To further ensure a fair test, all aero socks were measured so the socks were worn in exactly the same position, with fine adjustments of the socks taking place in the testing position. Our rider selected a comfortable position that could be held for the duration of all tests and we used an outline software to ensure the same position remained, along with a sustainable cadence which was measured by both the integrated wind tunnel data system and a power meter / computer.
The Data

Our results show a significant saving when using the Performance Watts Aero Socks.

We have used our sock as a reference so that the chart below shows how many watts have been lost compared to using our aero socks. There was only two socks at two different speeds which tested faster, each of those were by less than 1 watt. However at a speed of 55 & 60 kmph, our socks outperformed all market leaders which were included in the testing. The table below shows how many watts have been lost when compared to our aero socks at varying speeds.

All our data was processed by the tunnel manager at the Silverstone Sports Engineering Hub and closely analysed post testing to prove our results are true and accurate.
