Prism is Elite’s new bottle cage made of polymer-matrix composite reinforced with strong, high-resistant fiberglass. Prism’s distinctive feature is its side-load structure particularly designed for MTB riders who need to focus on ground conditions and optimize times and procedures of their hydration process with an easy release and insertion of the bottle, which is ideal for smaller bike frames or sloping top tubes. Prism Right has a normal opening to the right when mounted on a sloping cross down tube, but you can change the direction of entry of the bottle when mounted on the main tube of the bike, the seat tube.
