freerad luggage

Here is the whole bike with the Free Radical luggage attached. The luggage consists of 2 light weight aluminium U-frames to each of which a canvas sling is attached with webbing strap. The prongs of the U slip into the open upper ends of the four "pillars" you saw on the Free Radical in earlier pictures. The inner surface of each sling is waterproofed. Xtracycle calls these (frame plus canvas) units "FreeLoaders".
