EZ Hydro-Gains®: The Fastest BTS Hydration System Tested at Silverstone

If you are looking for a faster BTS hydration system, a more aerodynamic triathlon hydration system, or a rear hydration setup that has been properly tested against leading alternatives, the EZ Hydro-Gains® has been built for exactly that purpose.

In independent Silverstone Wind Tunnel testing, the EZ Hydro-Gains® was tested against leading competitor hydration systems to measure real aerodynamic performance, speed potential, and practical setup versatility.

Independent Silverstone Wind Tunnel Testing

The EZ Hydro-Gains® underwent extensive aerodynamic testing at the Silverstone Sports Engineering Hub. The goal was simple: compare our rear hydration system against leading competitor BTS hydration systems in controlled test conditions.

This allowed us to see how the EZ Hydro-Gains® performed not just in theory, but in measurable aerodynamic data.

EZ Hydro-Gains® Came Out On Top

Across multiple test scenarios, the EZ Hydro-Gains® outperformed competing products, reducing aerodynamic drag by around 3–4 watts.

For triathletes and time trial riders, that matters. Lower drag means greater efficiency, helping athletes ride faster for the same effort or conserve energy over long-distance races.

A Fair Comparison Against Competitor Hydration Systems

Competitor systems were configured in their most aerodynamically optimised setup to ensure a fair comparison.

Even with competing hydration systems set up as efficiently as possible, the EZ Hydro-Gains® was still faster than every competing hydration system tested.

Proven With Elite Athletes

Testing was carried out with pro triathletes Kellie Branagan and Joran Driesen, helping demonstrate how EZ Gains products perform in elite-level racing setups.

EZ Gains products are trusted by over 400 pro athletes worldwide, showing the confidence that elite athletes have in our aerodynamic cycling and triathlon products.

Wind Tunnel Data That Shows the Difference

The results shown in the wind tunnel data demonstrate that the EZ Hydro-Gains® consistently outperformed competing brands in aerodynamic testing.

Across multiple test scenarios, our system delivered lower aerodynamic drag, helping riders achieve greater efficiency and maximise speed on the bike.

Fast Does Not Mean Less Versatile

The EZ Hydro-Gains® is not just built for speed. Its adjustable, highly versatile design allows athletes to optimise their setup for comfort, hydration access and bike fit without sacrificing aerodynamic performance.

That makes it a strong option for athletes who want the fastest BTS hydration system, but still need a practical setup for training, racing, and long-course triathlon.

Built for Real Triathlon Setups

A fast triathlon hydration system needs to do more than test well in isolation. It needs to work on real bikes, with real athletes, in real race positions.

The EZ Hydro-Gains® has been designed to sit cleanly behind the saddle, helping reduce drag while keeping hydration accessible when it matters most.

Speed, Stability and Hydration Access

For long-course triathlon, bottle access and bottle security are just as important as aerodynamic performance. The EZ Hydro-Gains® gives athletes a fast, secure and practical rear hydration solution for racing and training.

Whether you are racing Ironman, 70.3, time trials or long-distance events, an aerodynamic BTS hydration system can be one of the most effective upgrades on the bike.

The Fastest BTS Hydration System We Tested

The Silverstone Wind Tunnel results showed that the EZ Hydro-Gains® was faster than every competing hydration system tested.

If you want a proven, adjustable and aerodynamic BTS hydration system for triathlon or time trial racing, the EZ Hydro-Gains® delivers speed, versatility and performance in one complete setup.
