Using this Aeroe bikepack dry bag is a breeze. First, decide whether you'll use it with the Spider Rear Rack or the Handlebar/Front Fork Cradle. To attach it, loop the built - in straps of the rack or cradle through the dry bag's built - in loopholes. Make sure it's firmly secured. When it comes to packing, you can put in all your cycling essentials like extra clothes, snacks, and a small tool kit. The quick - release system allows you to access your stuff quickly whenever you need it. As for maintenance, after each use, if the bag gets dirty, simply wipe it down with a damp cloth. Keep it in a cool, dry place when not in use. Don't overload the bag; stick to the recommended load capacity of 4kgs (9lbs) to ensure its long - term durability. Also, be careful not to scratch the heavy - duty TPU material.
