Using this Lezyne bottle cage is easy. First, find a suitable position on your bike frame and use the oval mounting holes to fine - tune it. Then, simply slide your bottle into the cage from the side. When riding, don't worry about the bottle falling out, as it holds securely. As for maintenance, just clean it regularly with a damp cloth. Avoid using harsh chemicals as they may damage the cage's composite material. And if you notice any signs of wear, check the cage's integrity to ensure it still holds your bottle safely.
