A durable and waterproof downtube bag that maximises frame storage space on bikepacking trips.

Securely fastening to downtubes and similar diameter tubes, the Expedition Downtube Pack is a versatile and compressible pack, ideal for carrying tools and spares. A wide velcro Hypalon Stability Strap attachment fits to tubes of varying diameters and evenly compresses contents whilst foam bumpers and silicone further enhance pack stability. Asymmetrical tapering at the base of the pack prevents any contact with chainrings.

Please Note: We do not recommend mounting on tubes with a circumference of less than 9.5cm, such as seat stays and forks.
