The Expedition Downtube Pack is designed for storing items underneath the downtube on bikes without accessory mounts.
The 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.
We do not recommend mounting the Expedition Downtube Pack on tubes with a circumference of less than 9.5cm, such as seat stays and forks.
The Expedition Downtube Pack (1.5L) has been designed to secure to 12-18cm circumference tubes.
