How the EZ Hydro-Gains Makes You Faster!
Verfiried through our own wind tunnel testing and several external sources. Learn exactly how the EZ Hydro-Gains will make you faster, and by how much.
Save Up to 17 Watts!
Independently verified through Fast or Fiction, their data shown here shows how you can save a lot of watts through different configurations when compared to no rear hydration system. Click to zoom in!

How the EZ Hydro Gains Reduces Drag:
Airflow over a triathlete forms a large chaotic wake behind the rider, this creates pressure drag which overall increases their aerodynamic drag. With an aerodynamically efficient rear bottle system, like the EZ Hydro Gains, the area behind the rider is 'filled in' reducing the size of this chaotic wake and overall reducing a riders CdA. This difference in airflow is simplified and shown in the diagrams to the left, click between the images to see how you can reduce your Aerodynamic Drag by using the EZ Hydro Gains!
The Fastest Bike Splits - Follow The Steps
The Fastest Set Up is a double 500ml /750ml Circular Bottles 0-6 Degree from level surface, with the bottles as close to the bum as possible, in general every test feedback has reported the closer to the bum the bottles are the faster it is. "so any systems with the bottles away from the bum are slower including any extra fins away from the back of the bike, any vertical bottles are slower, horizontal and close to the bum slightly lifted of the saddle has always tested faster."

Consistently Faster than Other Setups - Single or Double Bottle
Hundreds of professionals have tested the EZ Hydro-Gains vs their own highly dialed in set ups and consistently save watts! Below are some examples!
Some of the Pro athlete's we have had feedback from: Sam Laidlow, Caspar Stornes, Jelle Geens, Taylor Knibb, Danielle Lewis, Steph Clutterbuck, Kristian Hogenhaug, Solveig Lovseth, Katrine Grasboll, Chelsea Sodaro and so much more endless feedback!!
Faster than Canyon Aerofin
Silverstone Wind Tunnel Tested for a proven 6 watts for professionals!
EZ Hyrdo-Gains
Unmatched speed in every test. The EZ Hydro-Gains achieves this advantage by positioning its bottles horizontally and directly against the athlete's body. This is the most aerodynamic arrangement possible, effectively closing the gap that typically increases drag on other systems.
Faster than Standard Rear Bottle Holder
Silverstone Wind Tunnel Tested to be faster at all speeds and up to 6.6 watts with only the single bottle setup.

IRONMAN 70.3 WORLDS
Over 30% of the Pro Field at Ironman World Champs Marbella
will be benefiting from the EZ Hydro-Gains system!
This chart (prepared by our qualified aerodynamics engineer, Josh Small) shows the average time savings achievable at Ironman 70.3 Marbella using the EZ Hydro-Gains.
The comparison was made against setups with no rear bottle or a vertical/slightly angled bottle.
While gains may be smaller if you’re already using a more aerodynamic system — similar to what Sam Laidlow previously used — even he’s now upgraded to the EZ Hydro-Gains for maximum performance
When every second counts, aero precision and secure hydration make all the difference.
EZ Gains Dominates the PRO Field at Kona
EZ Gains — The Most Widely Used Aero Brand at the Ironman World Championships
With over one-third of the pro field using our products, EZ Gains is officially the most popular aero brand at this year’s championships!
This analysis — prepared by our qualified aerodynamics engineer, Josh Small — highlights the average time savings achievable at Ironman Kona using the EZ Hydro-Gains system.
The EZ Hydro-Gains was compared against setups with no rear bottle or a vertical/slightly angled bottle.
When it comes to speed, precision, and reliability — every watt and every second counts.
Worried about bottles falling out?
Latest News
The safest bottle holder system, "bump tested " this is due to the positioning of the cage, its a lot easier for a bottle to fly out of a vertical holder system rather then a horizontal system due to the force it takes to take a bottle out from the side, its almost impossible.
Weight testing to 33lb of weight and they still held firm, over 600,000 kilometres of road testing with 750ml bottles.
Also EZ Gains individually make the saddle clamps "and exceeded some existing clamps" for each seat giving you an exact fit rather then a universal clamp which will never exactly fit your saddle.
Another main factor is, the athletes do not need to lean as far back to grab there hydration, thus giving them more control of there bike when hydrating and exchanging bottles.
"Ironman Triathlon and World Triathlon have confirmed that EZ Hydro-Gains is legal to use in draft–illegal races and conforms to safety standards set out (BSI -ISO9001-ISO14001 5.03 Ironman (World Triathlon) exceeding the standards of a reputable safety standards organization (such as CPSC, ISO, or other equally reputable safety standards organizations)"
