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.

Created for road riding and long-distance tours, the Expedition Series is built from a lightweight material that provides unparalleled waterproofing and defence from the most punishing conditions.
The Expedition Downtube Pack (1.2L) has been designed to secure to 12-18cm circumference tubes.
The 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 top tube bag remains completely waterproof.
Wash the Downtube Pack by hand, using a mild diluted soap if necessary. Afterwards, let it air dry.
Do not machine wash, machine dry, or iron.
We’re an independent, family-run business of cyclists, makers and problem solvers, brought together by a shared mission to find better ways to explore the world by bike.
Apidura was born from necessity; pioneering ultralight, rackless packing systems to help us take our love of cycling further and allow riders to unlock their instinct for adventure. As devoted adventure cyclists, we design with our fellow riders in mind, creating products that address genuine needs and bring new value to the bikepacking scene. We create the best packs we can, using technical materials and precision crafting techniques – and when we find a way to improve them we do so straight away and without fanfare. We don’t do ‘seasons’, limited editions or discount our gear – we simply create the best possible technical bikepacking gear that’s built to last.
