Fit Werx is happy to be one of the first fit studios in the world to offer AiRO’s proprietary Computational Fluid Dynamics (CFD) software. By pairing the skills and biomechanical awareness of a qualified fitter with the power of AiRO, we can analyze equipment and positioning variables for you faster and at a lower cost than in a wind tunnel. AiRO is an impressive software package that brings the immense power of AiRO’s servers to us via the internet. If you have ever wanted to work on aerodynamic details in a wind tunnel, we now offer you the ability to work with aero guru Dean Phillips and AiRO from the convenience of the fit studio in Peabody. Dean + AiRO = No Compromises.

Contact us for additional information or to schedule an aerodynamic analysis of your position and equipment.

What is AiRO?

AiRO is a program that performs CFD (Computational Fluid Dynamics) to measure the aerodynamic impact of changes you make to a rider’s position. Definitions of CFD can be quite lengthy and detailed. Basically, it is a model that analyzes and predicts fluid flow around an object. This is very similar to what a wind tunnel does with air flow. AiRO has harnessed the power of streaming and the cloud to enable relatively quick data transfer, allowing their servers to perform remote analysis from almost anywhere with a reasonably fast internet connection. AiRO can accurately calculate your CdA (Aerodynamic drag coefficient) by taking a digital scan of your position. Before having access to CFD, the only ways to measure your CdA were wind tunnel testing, velodrome testing, or field testing using virtual elevation or aero sensors with a power meter. All of these other methods are time-consuming and/or expensive. AiRO allows us to provide aerodynamic analysis that used to take a whole summer of testing (or a long and pricey trip to a wind tunnel) in a matter of hours.

The AiRO analysis process begins by taking multiple photos and measurements of the rider to create a digital twin. Once the twin has been created, we can run multiple simulations, trying different positions and equipment. In addition to your digital twin’s CdA value, you can see a 3D illustration of where air is flowing. After all simulations are run, you receive an AiRO Fit Report summarizing your results. AiRO is a powerful fitting analysis and validation tool. It does not change the approach we have always taken at Fit Werx, where fundamental fitting principles are not ignored. Our goal is always to find a comfortable, powerful, and sustainable aerodynamic position that helps you achieve your riding goals. A fast position does not need to compromise any of these principles.

We recommend AiRO as a polishing tool that can be used both during and after your bike fitting. With the AiRO program at Fit Werx, any triathlete or cyclist interested in a wind tunnel session can now access the same results at a much lower cost and with a much lower time commitment.
