Dummy & Big Fat Dummy Rail Instructions
Hi there. Thanks for spending your hard-earned cash on this Surly product. Surly stuff is designed to be useful and durable.
We’re confident it will serve you well for years to come.
Surly Dummy Rails were designed to support our Dummy Deck and Dummy Bags. They fit all longtail frames(including the Big Dummy) using Xtracycle’s design standards.
Our Dummy Deck bolts directly to the Dummy Rails using M5 metric hardware, unifying and stiffening the entire system.
We include 20mm-long stainless steel flanged button head machine screws with the Dummy Rails for this application.
The threaded deck-attachment bosses, located along the tops of the Dummy Rails also serve as spacers. These 5mm-tallstandoffs create space between the rails and the deck for bag straps, Junk Straps, webbing, and cords.
Threaded bosses, located at the rear of each rail, provide a mounting location for a water bottle cage or other accessories suchas lights, cameras, action, pumps, flags, horns, light saber scabbards, disco balls, spittoons, cornucopias, etc.
Our Dummy Bags were designed to be fully compatible with our direct-mount rail and deck system. Non-Surly bags mayor may not be compatible with our system, due to the placement of the threaded bosses on the rails.
We highly recommend you have your Dummy Rails installed by a competent professional bicycle mechanic.
WARNING: Cycling can be dangerous. Bicycle products should be installed and serviced by a professional mechanic.
Never modify your bicycle or accessories. Read and follow all product instructions and warnings including informationon the manufacturer’s website. Inspect your bicycle before every ride. Always wear a helmet.
•	Check with your bicycle’s manufacturer to verify proper fit, mounting points, bicycle cargo load capacity, andcompatibility for carrying cargo. Do not exceed the bicycle manufacturer permissible load
