Materials & care

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 diameter of less than 30mm, such as seat stays and forks.


The Expedition Downtube Pack is cut from a three-layer laminate fabric that was developed specifically for Apidura. The material is lightweight, and is highly resistant to tears and abrasion. Notably, it’s welded together at the seams, creating a watertight seal that ensures the down tube bag remains completely waterproof.


Wash the downtube bag by hand, using a mild diluted soap if necessary. Afterwards, let it air dry.

Do not machine wash, machine dry, or iron.



The Expedition Downtube Pack (1.5L) has been designed to secure to 12-19cm circumference tubes.
