F A Q
FAQ
What is the TEMPO! Wind Tunnel®, and why is it important?
The FUSION TEMPO! Wind Tunnel® is a purpose-built aerodynamic testing facility designed to optimize sportswear and cycling equipment. Unlike traditional wind tunnels, it focuses exclusively on the unique needs of endurance athletes, enabling precise testing to improve speed, efficiency, and performance.
Why does aerodynamic drag matter in cycling, running and triathlon?
Aerodynamic drag is the resistance athletes face when moving through the air. It accounts for a significant portion of the effort in cycling and running, especially at higher speeds. By reducing drag, athletes can go faster with less energy or maintain their speed with greater efficiency.
How does Fusion test its products in the wind tunnel?
We use a structured approach: small, focused batches of 2-3 products are tested repeatedly to ensure consistent results. Each session evaluates fabric textures, body shapes, and product designs to refine and optimize performance step by step.
Can wind tunnel testing help create personalized sportswear?
Yes. Wind tunnel testing allows us to tailor sportswear to different body shapes, athletic disciplines, and performance goals. For instance, we can design garments specifically for high-speed cycling or endurance running based on individual needs and preferences.
What makes the TEMPO! Wind Tunnel® different from others?
Most wind tunnels are adapted from industries like automotive or aerospace, often requiring compromises for sports applications. The Fusion Wind Tunnel was designed from the ground up for cyclists and runners, ensuring the airflow, sensors, and testing conditions accurately simulate real-world performance.
How does textile design impact aerodynamics?
Textiles play a critical role in reducing drag. Specific textures and materials can manipulate airflow, improving efficiency at different speeds and conditions. The wind tunnel enables us to test how fabrics interact with air and adjust their design for maximum performance.
Why isn’t all testing done outdoors?
Outdoor testing is inconsistent due to variable factors like wind, weather, and terrain. The wind tunnel creates a controlled environment where we can repeatedly test and refine products with scientific accuracy, ensuring reliable results.
What is CDA, and how does it relate to performance?
CDA (Coefficient of Drag Area) measures how much drag affects an athlete at a given speed. It’s calculated by dividing drag force by air pressure. A lower CDA means an athlete can move faster with the same effort, making it a key metric in performance testing.
How does Fusion use wind tunnel data to improve its products?
The wind tunnel provides precise data on aerodynamics, fabric performance, and body positioning. We use this data to innovate new designs, adjust existing products, and create sportswear that is scientifically proven to enhance speed and efficiency.
What are “marginal gains,” and why are they significant?
Marginal gains refer to small, incremental improvements that add up to significant performance boosts. In competitive sports, these gains can be the difference between winning and losing. The FUSION TEMPO! Wind Tunnel® helps us identify and capitalize on these opportunities.
