King Cage water bottle cages are made from steel, plastic, or carbon fibre. Cages were never made of titanium, until Ron Andrews made it so. Titanium is notoriously difficult to weld and work with. It’s also more expensive than steel, but lighter and more robust, too. Proudly made by hand in Durango, Colorado. King Cage are one of a handful of builders making titanium bottle cages in America.
