Surly Big Dummy Frameset
$1,050.00
Big Dummy is a long-tail cargo bike, which means that not only can you haul a serious amount of cargo, different accessories can be added to your Big Dummy frame and deck depending on what you want to carry. Being a dedicated single-piece frame, instead of an add-on to an existing bike, it’s stiffer and resistant to torsional flex, which provides a better ride and longer lasting frame than long-tail add-ons. Like all Surly's frames, it’s made of size specific, 4130 CroMoly steel – a tube set engineered for cargo that sports lots of little touches that you’ve come to love in a Surly, like clearance for big tires and the use of common component sizes. Figure on being able to carry about 200 pounds (90kg) of cargo. The load weight, and how it’s loaded, will affect the handling somewhat. Also, plan on using gears, especially as cargo weight increases. This may seem obvious, but as you get comfy with it, you will use your full range of gears as never before. The included Dummy Rail Collars provide a secondary retention system for the rack, as well as stiffen the rack system so you can safely carry a passenger.
Surly Big Fat Dummy Frameset
$1,599.00 - $1,650.00
The Big Fat Dummy is a long tail cargo bike that took a few too many doses of growth hormones. At first glance, you might say that Surly just put bigger tires on a Big Dummy. But if you said that, you'd actually be very wrong so just… don't. Think of Big Fat Dummy as more of a second or third cousin to Big Dummy rather than a brother. They share some of the same DNA and look sort of similar, but they're two very different bikes and really only interact when they both reach for the potato salad spoon at that family reunion that no one really wants to be at anyway. Now that that's out of the way, let's get down to the nitty gritty of what makes this hulking beast of a bike tick. Surly's goal with designing a cargo bike around fat tires was to create the most stable, stiff, and traction-laden ride possible while hauling a ton of stuff. Big Fat Dummy has a longer toptube and slacker headtube than its more svelt cousin giving it a nice, predictable, and stable ride. They also used thinner, lighter tubing to construct its cargo area so while it's an overall burlier bike, there's not much difference in weight. Big Fat Dummy accepts either 10mm or 12mm axles in the rear with a spacing of 190/197mm. That big ‘ol spacing equates to one thing: tire clearance for days. Big Fat Dummy maxes out at a massive 26 x 5.25" tire.* While that large of a tire provides the most traction and stability a bike can possibly offer, it's also a lot of rubber to push and might not be for everybody. Luckily, Big Fat Dummy is also a blast to ride with 3" tires too. It uses the same 100mm suspension-corrected fork as the Wednesday, meaning if you want to add a little squishy-squishy to your ride, you can throw a Bluto on and let ‘er rip. If you intend to carry a passenger on your Big Fat Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. 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. All Big Fat Dummy framesets and bikes ship with a Dummy deck, rails, bags, and the aforementioned Dummy Rail Collars so you can immediately start hauling cargo — human or otherwise. Big Fat Dummy is ready and willing to carry all sorts of crap — literally. It's already in use on an organic farm in Ecuador so it's likely that it's hauled some form of manure by now. *Using a 26 x 5.25" tire will cause some drivetrain limitations. For all the nuts and bolts of compatibility read Surly's blog on the subject.
All-City Big Block Frameset
$499.00
The Big Block represents All-City's vision of the ideal track bike for everyday life. Take it to the streets or the boards. Wherever you ride it, the Big Block will hold up its end of the deal. All-City's proprietary 612 Select double-butted chromoly steel soaks up bumps and sprints like a champ. Each piece of tubing on every frame size has been carefully scrutinized and specifically chosen to create the best ride possible. This includes butting placement, tubing diameter, and wall thickness. And because it's destined to see usage beyond the veoldrome, it fits a 32c cross tire and has a single set of water bottle mounts for all day in the saddle. The front and rear of the bike are drilled out for a brake, so single speeding (or double brake fixed) is no problem. The package is finished off with a custom headtube badge, brazed-on seat collar, custom bottom bracket, and signature Hennepin Bridge dropouts. An E.D. coating for rust prevention is applied before the classic wet paint finish. Attention to detail is All-City's mantra and it shows in every aspect of this meticulously-designed, beautifully-constructed track racer.
All-City Nature Boy 853 Frameset
$1,150.00
All-City's Nature Boy Disc is your one-stop ride for weekend racing and weekday riding. Race-proven geometry in a classic and durable Renyolds 853 steel frame with a Whisky No.9 thru-axle fork with carbon blades make for a memorable ride both on and off road.

And all the usual All-City details are present, including rust-fighting ED coating, signature All-City stainless steel dropouts, and a stylish integrated seatpost clamp.
All-City Space Horse Disc Frameset
$650.00
Even if you own a different bike for everything, it's still necessary to have one that can do it all. That bike is the Space Horse. It's become a cult favorite because of its classic styling and ability to handle just about any task or terrain. All-City's Space Horse Disc frameset allows you to build your perfect bike with the addition of all-weather control disc brakes. The geometry is a mix of traditional road and randonneur, with a relatively short rear end and a bottom bracket that’s slightly lower than a standard road bike. This gives it both agile handling for riding unbridled and increased stability when loaded. This blend of geometry and 612 Select tubing create a bike that is capable of quick road centuries, gravel racing, commuting, and of course loaded touring. The frame accommodates front and rear racks, fenders, and tires up to 42c in size for the 700c bikes and 45c for the 650B version. It also utilizes a dropout with a replaceable derailleur hanger. All of the classic All-City touches are present: signature brazed-on seat collar, pantographed bottom bracket shell, pump peg, reinforcements on the bottle bosses, and a beautiful lugged crown fork. The fork sports both a double eyelet on the dropout and mid-blade mounts to allow you to use pretty much whatever front rack you wish.

Surly Big Dummy Frameset
$1,050.00
Big Dummy is a long-tail cargo bike, which means that not only can you haul a serious amount of cargo, different accessories can be added to your Big Dummy frame and deck depending on what you want to carry. Being a dedicated single-piece frame, instead of an add-on to an existing bike, it's stiffer and resistant to torsional flex, which provides a better ride and longer lasting frame than long-tail add-ons. Like all Surly's frames, it's made of their size specific, 4130 CroMoly steel – a tube set engineered for cargo that sports lots of little touches that you've come to love in a Surly, like clearance for big tires and the use of common component sizes. Figure on being able to carry about 200 pounds (90kg) of cargo. The load weight, and how it's loaded, will affect the handling somewhat. Also, plan on using gears, especially as cargo weight increases. This may seem obvious, but as you get comfy with it, you will use your full range of gears as never before. It's suitable to loaded as well as unloaded riding. Bags, deck, rails, and rail collars are all designed to improve on previous offerings and work together to make sure your stuff is transported with safety and stability. It's an unbending interface, which when you're carrying lots of cargo, is a good thing to have. Get creative, and get hauling. If you intend to carry a passenger on your Big Dummy, Surly requires use of their 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. They've tested the Maxxi Yepp seat. Yepp makes an adaptor that allows their seat to mount onto Surly's deck. It works well with the Big Dummy. At this time other child seats are not recommended and will void your warranty. Surly is testing other options. Note: keep in mind Big Dummy weight limits when carrying a passenger.
