Description The Apidura Expedition Downtube Pack 1.2L is designed for storing items underneath the downtube on bikes without accessory mounts. The Apidura Expedition downtube bag securely fastens to the downtube and similar diameter tubes to provide a versatile and compressible storage space for spares and long-distance essentials. It has enough capacity for a 710ml water bottle, allowing it to be used as a bottle holder bag for bikes with limited bottle storage space within the main triangle. Downtube bags for bikepacking bring the benefits of accessory mounts, with the freedom to mount the bag wherever it is needed. The single motion velcro attachment and stability system means the pack mounts securely and easily to tubes of varying diameters. The waterproof, seam-welded construction ensures the contents remain clean and dry. This pack is designed to work without mounts or a cage. If you require a cage-mounted pack, check out the Apidura Expedition Cargo Cage Pack.
