Why So Many Pros Choose EZ Hydro-Gains

With over one-third of the female pro field racing with EZ Hydro-Gains, rear hydration strategy isn’t guesswork, it’s a performance decision. Riders choose it because it’s:

  • Aero-optimised: bottle(s) placed close to the rider to reduce wake and drag.
  • Secure by design: custom saddle-specific mounts with tested retention over rough roads.
  • Race-proven: selected by top professionals for reliability and speed on the biggest stages.
