Dummy Rails support Dummy Bags on your Big Dummy cargo bike, and Surly's Dummy Deck bolts directly to them, stiffening the whole system for a more stable load. Dummy Rails are made of light, strong aluminum and were designed in conjunction with the Dummy Deck and Dummy Bags; each component works best when used with the others. Like all Surly products, they've built in lots of useful details. For example, the deck-attachment bosses stick up from the rails to create space between the deck and rails, providing windows to route tie-down straps and cordage; and threaded bottle cage bosses located at the rear of each rail provide mounting locations for accessories: bottle cages of course, or lights, cameras, pumps, flags, horns, light saber scabbards, disco balls, spittoons, cornucopias, etc. Dummy Rails will work with cargo frames (including the Surly Big Dummy) built around Xtracycle's longtail standards.
