Ironman 70.3 World Champ
Over 40% 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® Tests on Old GBR Suit vs New Huub GBR Suits
Tests were conducted at Silverstone Sports Engineering Hub wind tunnel, probably one of the best testing facilities in the world, the engineer was independent and employed by Silverstone Sports Engineering Hub, and the tests were carried out by EZ Gains® with a member of Age Group News present to validate results.
EZ Gains tested adding an Aero Bar Cover at the front of the bike to replicate an aero cockpit. We feel this would be classed as a fairing so will not go into production.
