The Search for Free Speed: Inside EZ Gain's Wind Tunnel Season

Up Next: Marc Dubrick, 6th August

The mission to find the fastest setup continues. On 6th August 2026, we're taking Marc Dubrick back to the wind tunnel to analyse and optimise his setup, helping uncover valuable time savings and every possible aerodynamic advantage.

Keep an eye on our Instagram to find out the watt savings.

At EZ Gains, we believe the fastest bike split isn't just about fitness, it's about the marginal gains hiding in your position, your kit and your setup. That's why we keep going back to the wind tunnel, working with everyone from World Champions to first-time age groupers to find every last watt.

Here's a look at some of our recent sessions.

Silverstone: A World Champion Chooses Hydro-Gains®

Following extensive testing at the Silverstone Sports Engineering Hub, Ironman World Champion Casper Stornes has chosen Hydro-Gains® as part of his race setup.

Designed to optimise rear hydration positioning while minimising aerodynamic drag, the EZ Hydro-Gains® has become a key component in Casper's pursuit of maximum performance at the highest level of triathlon.

He wasn't the only one putting in the hours in the tunnel that day:

• Sam Dickinson — setup optimised in the wind tunnel, with the BTA system and Hydro-Gains® helping unlock valuable time savings.
• Caroline Livesey — a wind tunnel session that revealed a 40-watt improvement through setup optimisation, proving that every detail matters when chasing performance.
• Fenella Langridge — a 15-watt saving, with the EZ Disc Wheel Cover performing strongly against her current setup.
• Joe Skipper — one of the most tunnel-tested athletes in the world, constantly refining his race position. Testing showed the EZ Disc Wheel Cover performing strongly against his current wheel setup, proving there are still gains to be found even for someone this dialled in.

More Time in the Tunnel, More Watts Saved

On our latest wind tunnel trip, two more athletes walked away with serious numbers:

• Kellie Branagan — an age grouper who saved over 30 watts by optimising her setup with our products, including the BTA system, Hydro-Gains®, veloToze® Calf Guards, and more. Proof that these gains aren't reserved for the pros.
• Joran Driesen — unlocked significant watt savings by optimising his race setup, using our performance products to improve aerodynamics and maximise efficiency.

Stateside: Indiana Wind Tunnel Testing with Jelle Geens

The search for speed took us across the Atlantic too. World Champion Jelle Geens joined us at the wind tunnel, where we worked together to optimise every detail of his race setup.

By analysing his position, equipment, and aerodynamics, we helped identify opportunities to maximise performance and find every possible advantage — saving him a huge 20+ watts in the process.
