The Trailfront Cage handlebar bag consists of two parts: a mount and a dry bag. This means the mount can stay on the bike throughout your bikepacking trip, while you only need to take the dry bag with you for safekeeping. The included spacers let you position the mount perfectly for your specific handlebars. The bungee cords let you secure small items or clothing on the outside. The dry bag itself is waterproof and attaches to the mount quickly and easily with two buckles.
