The AeroGain Aero BTS Pro System is more than just a rear hydration mount. Developed through aerodynamic testing, it's designed to reduce drag while carrying everything you need for race day, transforming your hydration setup into a genuine performance advantage.
By improving airflow behind the rider, the BTS Pro has been shown to deliver up to 8 watts of aerodynamic savings, helping you ride faster without changing your position or producing any extra power.
Whether you're racing an Ironman, 70.3 or a UCI Time Trial, every watt counts.
Traditional rear bottle carriers often add drag and clutter to your bike. The Aero BTS Pro has been engineered differently.
Its aerodynamic design helps optimise airflow behind the rider while providing a secure mounting point for hydration and an integrated storage solution for your essential race equipment.
Everything is kept neatly behind the saddle, leaving your cockpit clean and your bike race ready.

Integrated storage compartment for tools and spares
Stable and secure over rough road surfaces
Lightweight race-ready construction

Inner tube or tubeless repair kit

Other race-day essentials
With everything stored neatly behind the saddle, your bike maintains a clean, professional appearance while keeping your equipment exactly where you need it.
Engineered for the demands of long-distance triathlon and time trial racing, the Aero BTS Pro remains secure over rough roads, reducing bottle movement and eliminating the rattling often experienced with traditional rear hydration systems.
