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.
