Using this bag is a breeze. First, open the water - repellent YKK zipper with the Hypalon puller, even if you're wearing gloves. Then, put your inner tubes and mounting levers inside. You can use the internal side mesh pockets to keep small items organized. To attach it to your bike's upper frame tube, use the adjustable velcro straps on the bottom and front of the bag. When it comes to maintenance, wipe it with a damp cloth if it gets dirty. Avoid using harsh chemicals as they may damage the Nylon Robic material with the PU coating. Also, make sure to keep it dry to maintain its water - repellent properties. And remember, don't overstuff the bag as it may affect its durability and functionality.
