Improve your aerodynamics and Save Up To Tens Of Minutes In Your Next Race Quickly And Inexpensively

Almost 90% of the power you use when cycling on a flat course is spent fighting aerodynamic resistance. The revolutionary Virtual Wind Tunnel technology makes aerodynamic testing quick, affordable, and accessible anywhere. Now you too can become as aerodynamic as the professionals.

If you want to get faster on the bike, there is no better value-for-money investment than a Virtual Wind Tunnel assessment. Watch the video below to learn how it works.

“Over the past year, I’ve been using the Virtual Wind Tunnel to optimize my position and inform my equipment choices for racing. My results were in close agreement with my data from a conventional wind tunnel, which validates this approach.


Testing with the Virtual Wind Tunnel is far more convenient, quick and affordable than a trip to the wind tunnel or velodrome, making aerodynamic testing more accessible for athletes, coaches, bike fitters and product developers. It’s a revolutionary step forward.”

How the Virtual Wind Tunnel will make you faster

When you ride a bike on a flat course, up to 90 % of your power goes to overcoming aerodynamic drag. Put simply, you're fighting the wind. With the virtual wind tunnel, it's possible to make improvements to your riding position, equipment setup or make equipment changes that can reduce your aerodynamic drag by 10 to 15 %.


To be able to make such improvements, you must be able to test your aerodynamic drag. In the past, such testing has been very difficult or very expensive, or both. This changes with the Virtual Wind Tunnel.

1

Affordable, accessible, and accurate testing

Testing in a real wind tunnel usually costs upwards of 1000$. The accessibility of wind tunnels is also very limited, so you may have to travel for it, and the process is time-consuming.

Testing at a velodrome is cheaper (or free), but access may still be limited, and the process is time-consuming. The biggest issue is that it's difficult to get accurate results if you're doing the test yourself. Unless you are very experienced, it's likely that you'll make some critical measurement errors.

The Virtual Wind Tunnel solves these issues. It's a much quicker and easier process than real wind tunnels and velodromes. It is very affordable, and you can easily replicate tests and compare results without the large risks of measurement errors from field testing. 

Virtual Wind Tunnel - Aerodynamic Analysis

Know your CdA (aerodynamic drag) and race time savings

You will get the CdA-value for each of the setups or positions you scanned. The CdA is basically your score for how aerodynamic you are, the lower the better. It can be used to estimate how fast you will complete a certain race distance,

When comparing two different positions or setups, you can therefore find out how much faster you will be over your goal race in one position compared to the other.

You can also find out the difference in speed at any given power output between your different tests. For example, at one riding position  and 250 watts, your speed could be 42.6 km/h, compared to 44 km/h for another position.

Compare different positions, equipment and setups

One of the best use case of the virtual wind tunnel is testing specific changes or alternatives in terms of riding position, equipment, or equipment setup.


For example, you may find that switching from water bottles on the bike frame to a between-the-arms bottle and a bottle cage behind the saddle can save you 6 minutes over the course of an Ironman.

Or that a more aggressive riding position could save you 15 minutes over an Ironman compared to your current position.

One scan, multiple tests with post-processing manipulations

Analysis of certain positions and setups can be analysed without needing to do a separate scan. This is called a "manipulation".

For example, you could ask to have two manipulations done of your baseline scan - one with changed arm angles and one with changed head position. All without having to perform or pay for a separate scan. 


Another example would be to compare different wheel profiles. You could do the scan with your standard training wheels, but through manipulations analyse and compare 30 mm, 60 mm and disc wheels. 


Note that not everything can be done through manipulations of a baseline scan. In general, changes that just require stretching the 3D model can be done, and simple equipment changes as well.

Used by amateur and professional triathletes and cyclists

Athletes of all levels, from amateur to some of the best professional triathletes in the world are already using and benefiting from the Virtual Wind Tunnel. Age-groupers have set new personal bests or qualified for Kona, and professionals have won and podiumed at international races of the highest level. 


Some examples of professional athletes using the VWT are Cody Beals, Alex Vanderlinden, Amanda Bohlin, and Andrew Bolton. And more are joining the cause constantly!

How it works

1. Scan

You will be sitting still on your bike indoors on a stationary trainer. A digital, three-dimensional model of you and the bike is obtained by capturing images with a 3D scanner. This takes 2-4 minutes per scan.


In some cases, a few different scans may be done. For example, when comparing different equipment setups or positions that can't be done through simple model manipulations in the analysis process. 

2. Analysis and post-processing

Advanced computational fluid dynamics analysis of the model then simulates how the flow of air moves around you and how much aerodynamic drag you’re creating.


Analysis of certain positions and setups can be analysed without needing to do a separate scan. This is called a "manipulation". For example, you could ask to have two manipulations done of your baseline scan - one with changed arm angles and one with changed head position. All without having to perform or pay for a separate scan. 

3. Apply results

Within a couple of days the analysis will be done, and the results (and optional full report, should you choose to order that) will be sent to you.


Now you'll have data to back up which riding position or equipment change or setup is the most aerodynamic for you. And you'll know how much time this can save you in your next race.

You'll know if your aerodynamics are currently good, bad or in-between. You can compare your results with a database of VWT clients, including both professional and amateur athletes. 

You'll even have the information needed to estimate how fast you'll be able to cover the race distance (assuming you know your realistic power target), which can help you set a time goal for the bike leg and the entire race.
