Salsa Cutthroat Rival 1
$3,499.00 - $3,699.00
Cutthroat brings speed to the mixed surface, ultra-endurance bikepacking race scene. Every aspect was designed to obliterate long-distance cycling route records. An evolutionary leap in all-road bikes, Cutthroat lets you ride long, hard, and fast in comfort. The full-carbon frame and fork deliver race-winning efficiency and offer Salsa’s Class 5 Vibration Reduction System to reduce energy-robbing trail chatter. The DT Swiss C 1800 wheels and Maxxis Ikon tires fly on fire roads and stand up to hours-on-end punishment, all while keeping rolling resistance and rotating weight down so you can keep pushing. The Cutthroat’s SRAM Rival 1x11 drivetrain offers secure, streamlined efficiency with a wide gear range shifted by SRAM’s crisp DoubleTap shifting to maintain speed and momentum in widely variable terrain. And, Rival hydraulic disc brakes deliver ruthless stopping power with precise modulation and a lightweight design; everything you want in a race-ready braking system.

Surly ECR 29+
$1,900.00
The ECR is Surly's answer to those times when you just need to escape to the woods for a while to get away from the humdrum of life. Those familiar with this steel mule know it’s designed around plus tires, previously of the 29” variety. A fully loaded 29+ bike is an excellent way to explore and get away for a while… if you’re of a certain stature that is. For smaller riders, it poses several challenges though. And no one wants new problems when they’re in the woods trying to escape old ones. To solve this, Surly redesigned the smaller sizes of the ECR to work with 27.5+ while the larger sizes are still equipped with 29+. All you medium specimens out there get your pick of the litter as Surly is offering that size in both options. Other updates to the ECR include and are limited to: Gnot-Boost rear spacing and a killer new beige paint job. It retains the abundant accessory mounts that we all know and love like Surly Trip Guide for brakes and derailleurs, fender, rack, and Bill/Ted eyelets, and a Rohloff torque arm slot. The 29+ sizes have two water bottle mounts and one set of Three-Pack bosses. You’ve got lots of options to bring all your “necessities” with you and still have room for excess baggage if you’ve got it.
Surly Big Fat Dummy
$3,175.00
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.

Surly Wednesday
$1,550.00 - $1,675.00
Wednesday is a great all-around fat bike that has the soul of a trail bike and mind of a touring bike. Wednesday sits in the middle of our Trail category, but don't let that fool you into thinking that's its only use. With Wednesday, we borrowed elements from some of our Trail and Touring models to create a versatile fat bike that can truly handle anything you want to attempt. If you do an equal amount of off-road touring as you do hitting trails, Wednesday's ability to play both parts equally will suit you well. Or, if you're looking for a fat bike and don't need the fattest tires on the market, Wednesday's 26 x 4.6" tire clearance is just the ticket. Any day of the week's a great day to ride a Wednesday. - Modern mountain standards: stealth dropper post routing, 44mm headtube, suspension correction, front and rear thru-axles - Full suite of useful braze-ons: front and rear racks, multiple sets of three-pack mounts, fenders - Full-forward, short chainstay position: 26 x 3.8 tires on 80mm rims; full-rearward, longer chainstay position: 26 x 4.6 tires on an 80mm rim

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.
