BIG DUMMY FRAMESET
Thanks for spending your hard-earned money on a Surly frameset. Seriously, we really appreciate it. You could’ve picked something else but
you didn’t, and that means a lot to us. We’ve put a lot of work into making a great riding bike that you’ll enjoy for a long time. Before you readany further take a minute and write down this frame’s serial number. If you should ever experience a problem with it, the serial number will
help us get things sorted, and if your bike is ever stolen the serial number is undeniable proof that it’s yours. So take a minute, flip the bikeover, and write it down. Your frame’s individual serial number is located on the underside of the bottom bracket (the part of the frame thathouses the crank bearings).

SERIAL NUMBER:______________________________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 information on the manufacturer’s website.
Inspect your bicycle before every ride. Always wear a helmet.
WARNING: Do not use forks exceeding 425mm axle-to-crown. Doing so will void the frame warranty and may result in damage orfailure of the frame and possible serious injury.
If you intend to carry a passenger on your Big Dummy, Surly requires use of our Dummy Rail Collars. These provide a secondary retention
system for the rack, as well as stiffen the rack system. These are included with MY17 Big Dummy bikes and frames, as well as available AM
for older Big Dummy bikes and frames [compatible with all generations of Big Dummy bikes/frames]. In addition, a stoker handlebar set up,
found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility.
If you are planning to carry a child on your Big Dummy, Surly recommends the use of a child seat. We’ve tested the Maxxi Yepp seat.
They make an adaptor that that allows their seat to mount onto our deck. It works well with the Big Dummy. At this time other childseats are not recommended and will void your warranty. We are testing other options. For the most up to date compatibility/options,check surlybikes.com/safety
Note: be mindful of Big Dummy weight limits when carrying a passenger.

CARE AND MAINTENANCE

Keep your frame clean. Dirt and road grime lead to oxidation and fading of the finish, and they make it hard to do a thorough inspection.
Dirt will accelerate any abrasion of the paint that comes from rubbing, such as places where the cable housing touches the frame. In extreme
cases, this type of abrasion could remove frame material. When your bicycle is not being ridden, store it where it will be protected from rain,snow, sun, etc. Rain or snow may cause the metal on your frame to corrode. We recommend applying J.P. Weigle’s Frame Saver to the insideof the tubes before the frame is assembled into a bike. If your bicycle was exposed to moisture during a ride, thoroughly dry the bicycle before
storing it. If water got inside the frame, tilt the bicycle to drain the water. If necessary, remove the seatpost and turn the bicycle upside down.
This is especially critical if there is a large amount of water inside. If water freezes inside your frame, the expansion of the ice can crack andrupture the structure.
Before storing your bicycle for an extended period of time, clean and lubricate the frame with a frame wax, polish, or protectant. Do not store
the bicycle near electric motors, as ozone from motors destroys paint. Before riding the bicycle again, follow the pre-ride checklist in part Cof your bicycle manual to be certain it is in good working order.

INSPECTION

Before every ride carefully inspect your frame for signs of fatigue. If any frame part shows signs of damage or fatigue, consult your dealeror replace the frame before riding the bicycle.
WARNING: An improperly modified frame, fork, or component can cause you to lose control and fall.
NEVER MODIFY YOUR FRAMESET.
WARNING: Attaching incompatible clamping devices to a fork can lead to fork breakage, causing a loss of control.
If you are not sure if a device is compatible, consult your dealer
