Using this top tube bag is a breeze. First, decide if you want to directly mount it on a compatible Salsa frame using the thumb screws provided, or use the included straps for Salsa and non - Salsa frames. Once it's attached, you can start filling it with your items. The one - hand operable zipper makes it easy to open and close while you're riding. Keep your frequently used items like energy bars, your phone, or a battery bank in the four - way stretch mesh exterior pockets for quick access. As for maintenance, simply wipe the bag down with a damp cloth when it gets dirty. Avoid using harsh chemicals as they might damage the 1000D Cordura nylon material. Also, make sure to empty the bag and let it dry completely if it gets wet. This will help extend the life of your top tube bag.
