Triathlon Aero Hydration System
Level up and integrate your bike hydration
The Aero Hydration System is designed to unlock the full potential of your triathlon bike. The aero bottle mounts securely to your stem with a solid and rattle free bolt connection. The design integrates into your tri bike aerodynamically, functionally and visually (STEALTH).
Your aerobars remain fully flexible and can be fitted precisely to your needs. The low center of gravity ensures stable and precise handling characteristics of your triathlon bike. This enables you to stay hydrated and maintain your optimal aero position over longer distances.

5 models for bike and size specific integration
Triathletes differ in their body dimensions and so do the sizes and geometries of their bikes and cockpits. Consequently, our models S1 - S5 are designed for specific geometry and size clusters. This athlete-centered multi-model approach ensures perfect integration without compromise – also for smaller frame sizes.
Size Guide
For certain bike models we provide a detailed allocation of our models S1 - S5 by frame size and stem length. For all other models refer to 'Other / General' for an overview of compatible stems and fitting templates for model allocation.
In triathlon, details make the difference. The Aero Hydration System combines streamlined aerodynamics, minimal weight and a robust design that is comfortable and reliable to use even under high loads. Production in Germany with high-precision injection molding technology and advanced blow molding processes ensures high-end quality and optimal material properties.
