The Prologo U-Cage is the perfect mounting system for long distance Triathlon races and long training sessions.
The revolutionary system allows you to mount up to two bottle cages, allowing you to have two water bottles or one for water and the other for tools and spares.
The U-Cage is aerodynamically designed and has been tested in a wind tunnel to reduce as much air resistance as possible.
This is one of the lightest rear hydration mounting systems on the market, thanks to its carbon injection structure.
