Using this Blackburn storage bag is a breeze. First, find the empty space behind your bike's head tube. Attach the bag using the hook and loop straps provided. Make sure it's secure before you start your ride. When storing items, put your CO₂ cartridge, tube, and tools inside. You can arrange them however you like to make the most of the 0.7L capacity. As for maintenance, if it gets dirty, just wipe it down with a damp cloth. Since it's water-resistant, it can handle a bit of rain, but try to avoid submerging it in water for long periods. Always check the straps regularly to ensure they're still in good condition and can hold the bag firmly in place.
