Birzman Aeroman Rear Hydration Carrier

The Birzman Aeroman is an award-winning adjustable rear hydration system with a 6061 alumium modular structure and multiple mounting holes which provide different attachment possibilities - stow the bracket to carry one single bottle cage at the rear end or extend the bracket to carry two bottle cages side by side. The arms mount onto the saddle rail at two adjustable angles to accommodate saddles of different shapes.
