Using this 8L Frontloader Bicycle Handlebar Bag is a breeze. First, attach it to your bike's handlebars using the two straps, special spacer mounts, and quick - release buckles. Make sure to use the backside head tube strap attachment to keep your load stable. When packing, place light and bulky items like sleeping bags and extra clothes inside. The removable 8 - liter waterproof drybag is great for protecting your stuff from water, so don't forget to zip it up tightly. If you want to save space, press the built - in air release button to get rid of the extra air. As for maintenance, after each use, wipe it down with a damp cloth to keep it clean. Store it in a dry place when not in use. Avoid dragging it on rough surfaces to prevent abrasion.
