The Ranger is a workhorse of a frame bag. Designed to make use of the full triangle, the Ranger is an off-the-shelf bag that fits a huge range of standard mountain and fatbike geometries. We used our wealth of knowledge from years of custom bag building to deliver on a bomber feature rich bag that you can swap to different frames for years to come. As frame bags are intended to carry dense items like food and water, we emphasize durability and fast access in the design and features. Ranger bags can be loaded full and still accessed while riding. Something that is impossible with higher bulk, roll closure frame bags.

Please check sizing chart for detailed dimensions and compare to measurements of your frame.
