Designed with a built-in, discreet holder for an Apple AirTag*, the Matrix Air Cage is a revamped take on our popular Matrix Team Cage. Featuring the same minimalist, dual-side-loading design, it goes one step further by cleanly hiding the AirTag between the bottle cage and bike frame for an added level of security. Its also constructed from the same lightweight, incredibly durable Composite Matrix material and goes one step further with its IPX7 waterproof rating keeping the AirTag dry. By developing it to be virtually indistinguishable from a standard water bottle cage, the Matrix Air Cage is a perfect solution to hide an AirTag and utilize ApplesFindMyapp to help locate a stolen or missing bicycle. And its been verified to work with Apples ultra-wideband signal. Lastly, it comes with a set of stainless steel TR25 security bolts, complete with an included tool bit.*Apple AirTag not included.*AirTagis a trademark of Apple Inc., registered in the U.S. and other countries and
