Wind Tunnel Analysis

This report summarises the weighted yaw sweep aerodynamic comparison between the original Hypersonic Speedsuit and the Hypersonic Mk2Speedsuit.

Nopinz uses wind tunnel testing to create apparel that performs where it matters most: in the real world.

While many brands highlight a single headline result, real riding is never that simple. Speed, position and wind angle are constantly changing, so testing one scenario alone does not give a true picture of performance.

That is why Nopinz uses a transparent wind tunnel protocol developed to better reflect how cyclists and triathletes actually ride. Testing is carried out across multiple speeds:45, 50 and 55 km/h and across dynamic yaw angles ranging from -7° to +7°. Rather than relying on one standout number. Nopinz calculates average CdA across the full test range to provide a more credible view of aerodynamic performance.

This approach helps ensure products are optimised not just for the tunnel but for open road riding, time trialling and triathlon. It also reflects the needs of a wider range of riders from elite racers to club level athletes.

Testing takes place at Silverstone and plays a key role at both the concept and final validation stages of product development. New suit ideas are prototyped, tested, refined and retested with fabrics, panel layouts and garment templates all assessed for real performance gains.

The process is time consuming and costly, but it allows Nopinz to make evidence based decisions and develop products backed by robust, repeatable data.

In short, Nopinz wind tunnel data is designed to be honest, relevant and representative of real world riding. Not just a sales headline.

 

Watts Saved

Speed (Hypersonic MK2 vs Hypersonic) across all yaw angles
45 km/h -7.8 W
50 km/h -10.7 W
55 km/h -14.3 W

Key Findings

  • MK2 demonstrates a consistent aerodynamic advantage across the weighted yaw sweep.
  • Peak aerodynamic saving reaches 14.3 W at 55 km/h.
  • Average saving across the tested speeds is 10.9 W.
  • Overall weighted CdA reduction is measured at 0.00653.

What This Means in Racing Terms

45 km/h ~7–10 sec over a 10 mile TT
50 km/h ~10–15 sec over a 10 mile TT
55 km/h ~15–25 sec over a 10 mile TT

Time estimates are modelled from aerodynamic power savings and will vary based on rider position, mass and course profile.
