Surly Big Dummy Rail Collars
$33.50
Surly's Dummy Rail Collars are nothing more than a simple clamping device that buttresses the connection between your Big Dummy Frame and the Dummy Rails. They increase the stiffness of the interface of these two parts and help keep your cargo from getting its salad tossed… unless of course your Dummy Bags are filled with tossed salad. These are designed specifically for use with the Big Dummy frame and Dummy rails, and will not work with Xtracycle rails. WARNING: Properly installed Dummy Rail Collars are required for carrying live cargo on your Big Dummy.
Surly Dummy Rails
$70.00
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.
