There is no limit to the variety of frame bag shapes except by the bicycle frame. Usually frame bags are small, handy storage compartments in which you can accommodate small parts and repair tools. There is no time-consuming assembly of holders necessary because these bags are attached with Velcro straps on the top tube. Noteworthy are the top tube pockets with map compartment. These practical helpers are not only stowage space, but also facilitate navigation by means of a map, as it is always visible in the field of vision.
