Frequently Asked Questions
Q. You run sessions from two wind tunnels, which one should I choose ?
We offer two different facilities to suit your budget. We have been providing wind tunnel sessions at Shrivenham for two years now and have developed a protocol which has enabled many riders to optimize their riding position and increase their performance. In 2009 we have taken this one step further and now also offer the Drag2Zero protocol out of the state of the art Mercedes GP F1 wind tunnel. This wind tunnel simulates the real world conditions very closely as we are able to test in a cross wind (yaw) and also because the tunnel is open jet. The ability to test in yaw means that it is possible to test different wheels and their effect on performance. For details of the specification and price of this tunnel please click here. Naturally the facility is more costly to run and is used by pro teams, amateurs and manufacturers looking for that extra level of accuracy. Compared to what is on offer elsewhere in the world, we believe that what we offer at both wind tunnels represents good value for money, taking into account the high costs of running wind tunnels and the gains that can be achieved out of a wind tunnel session.
Q. How much does a wind tunnel session cost?
For a first test a minimum 2 hour booking is required. For the Mercedes GP F1 wind tunnel we charge £799 for a 2 hours session. The Cranfield University wind tunnel at Shrivenham is charged at £490 for a 2 hour session.
Q. Where is the wind tunnel?
We provide sessions from two wind tunnels: one in Shrivenham Wiltshire which is part of Cranfield University and the other at Mercedes GP, Brackley, Northamptonshire.
Q. What can be achieved in a Wind Tunnel session?
During a 2 hour session there will be time to cover all general aspects of a rider’s position and this is adequate for most amateurs (for full details of what is covered in a wind tunnel session click here). For serious time trialists and triathletes it is possible to spend more time on specified positions either by booking extra time to add on or coming back (either to the Shrivenham tunnel or the Mercedes F1 scale wind tunnel). We provide you with a CD Rom after the test with the results and photos of different rider positions to enable those who come into the tunnel to really work on their position after the session.
Q. Do you have any products for me to test and buy in the tunnel?
We have a range of helmets and handlebars for you to try and you can then order these from us if you would like to buy. In the Mercedes GP wind tunnel we also have some different wheels for you to try out.
Q. What do I have to bring on the day ?
You should bring your bike, any wheels (at the Mercedes GP F1 tunnel only), bars, helmets and skin suits that you are keen to compare. If you would like to test with two bikes please let us know prior to booking as you may require more time. You should also bring energy drink and water. You will also need to wear glasses/a visor in the wind tunnels. If your bike is non standard in any way, e.g. size, you must let us know this at the time of booking as it may require modifications to be made to the rig.
Q. What time should I arrive for my session ?
You should arrive no later than half an hour prior to your wind tunnel session to allow time for meeting you and set up.
Q. Do I bring a heart rate monitor?
You only need to bring your heart rate monitor if you are using the Watt Bike.
Q. Do you measure power output?
The aerodynamic drag can be presented as a power gain or loss in watts. This information is provided as part of the results from the session. The power level on the resistance unit can be set at any level and is set appropriate to the rider to achieve consistent and realistic conditions.
Q. Can I bring my coach/friend along to the session?
Bringing your coach is a good idea as we will all be able to work together to increase your performance. We can also provide coaching as one of the options available. A wind tunnel session is a scientific process and in order for the best to be obtained from your session, distractions must be kept to a minimum. For this reason we limit attendance to the rider and one coach.
Q. Do I get my results to take away with me?
Following the test, we will produce a CD Rom with the results of your tests, including photographs, and send it to you. We aim to do this within a week of the test.
Q. Should I arrive in my cycling kit?
There are areas to change in both facilities so you do not need to arrive in your cycling kit although it will save time if you do.
Q. Can I arrange for photos to be taken of me in the wind tunnel?
As part of the report provided after the session you will be provided with photos of your “before and after” positions. Other photos should not be taken in the wind tunnel. If you require photos for sponsors etc, please let us know when booking and it may be possible to provide these.
