Using this bottle cage is a breeze. Just slide your water bottle into the cage. Thanks to its design, it'll hold the bottle firmly but you can still easily grab it when you're thirsty. When it comes to maintenance, a simple wipe with a damp cloth now and then will keep it in good shape. As for precautions, avoid using sharp objects to clean it as it may damage the carbon structure. And remember, this cage is designed for standard - sized water bottles, so using non - standard ones might affect its performance.
