The Birzman Aeroman Hydration Carrier is a premium rear hydration system developed for triathletes, time-trial riders and performance-focused cyclists who want flexible bottle storage with an aerodynamic and lightweight design. Its modular construction allows riders to customize bottle position and mounting angle according to saddle shape, riding position and race-day preferences.
Built from 6061 aluminium, the Aeroman combines excellent rigidity with low weight. At approximately 105 g including hardware, it provides a strong platform for hydration storage without adding unnecessary bulk to the bicycle.
The carrier uses a central adjustable bracket supported by two arms that clamp onto the saddle rails. These arms can be positioned at different angles, helping the system fit a variety of saddle shapes and rider configurations. The multiple mounting holes also allow the bottle cages and accessories to be arranged in several orientations.
When fully extended, the Aeroman can support two bottle cages positioned side-by-side, with three available mounting angles. This configuration is ideal for longer races or training sessions where additional hydration capacity is required.
For riders who prefer a cleaner and more minimal setup, the carrier can be folded or stowed to support a single rear bottle cage, with two different angle options. This gives riders the flexibility to choose between maximum hydration capacity and a more compact race configuration.
The streamlined structure is designed to sit behind the rider, helping keep the carrier within the rider’s aerodynamic shadow and reducing unnecessary exposure to airflow. This makes the Aeroman especially suitable for triathlon bikes, time-trial bikes and aerodynamic road cycling setups.
