The Expedition Frame Pack is designed for storing items within the main triangle, creating a lower centre of gravity and enabling more natural bike handling. The frame bag securely fastens to the top tube with velcro straps, and is useful for storing heavier items as part of a larger bikepacking setup. The result is an even, balanced load, making longer tours and multi-day trips more comfortable. The frame bag is equally useful when used on its own for storing essentials on a daily commute. It’s constructed from a lightweight fabric, custom milled to Apidura’s specifications and welded together at the seams to create a watertight seal. Zippers with protected closures ensure that kit stays dry, even in a sustained downpour. A battery lead/hydration hose port is handy for charging devices or staying hydrated on the road. Our frame bag sizing tool. will help you work out what size frame bag fits your frame and whether you have a Tall or Compact head tube.
