Surly Instigator 2.0 Frameset
$599.00
Say hello to Surly's rowdy, trail-shredding Instigator 2.0. The no-nonsense chromoly frame is made for charging hard and going big. It's super tough, yet handles nimbly and accelerates like mad. The heart of the bike is Surly's 26+ platform which has clearance for 50mm-wide rims and 2.75-inch tires, so you get endless traction and the rollover-action of a 27.5-inch wheel, coupled with the snappy, go-fast responsiveness of a 26-incher. The geometry is dialed for a 140mm travel suspension fork and features a long top tube and short rear end for more of the same fun. And this thing is versatile, the frame comes with dropouts for rolling singlespeed, or geared with a quick release or a 142x12mm through-axle with a Shimano direct-mount hanger.
Surly Karate Monkey 27.5+ Frameset
$625.00
Years ago the Karate Monkey helped start the 29” wheel movement and, as time’s gone by, many companies ­– Surly included – have experimented with even more wheel sizes. With so many different types and sizes of tires now on the market, riders have begun to understand the effect that tire width has on overall wheel diameter, and with ample tire clearance, you can see the benefits of multiple wheel sizes all on one bike. 27+ tires have the same rolling diameter as a 29” wheel, yet you get all the traction and flotation benefits of extra-wide knobbies. And that’s just the tires. The Karate Monkey frame has recently gotten a make over that includes the addition of features like internal dropper post routing, a new tubeset that uses the same trumpet tubes found on our Instigator 2.0, and a slight tweak in geometry that is more progressive and trail-oriented. The Karate Monkey uses a horizontal dropout with a derailleur hanger that features Gnot-Boost spacing, which gives the rider the ability to run any kind of mountain bike hub they choose. 10 x 135mm QR, 12 x 142, or 12 x 148 Boost will all work in the Karate Monkey frame. The frame uses a 44mm headtube for broad fork compatibility and is ED coated for an added layer of internal protection. If, at any point, you decide you want to throw on some skinny meats, standard 29” wheels and tires can be swapped in with no issue. If you want to round-house kick some trail right in the face, the Karate Monkey is your sled.
Surly Ogre Frameset
$575.00
Versatile doesn't even begin to describe the bike you can build with Surly's Ogre Frameset. It's fabricated from their signature chromoly with their tried and true 29er geometry. Load it up with racks or fenders or a trailer or all three, whatever your fancy, this frame is ready. Up front, Surly's Ogre fork is built as a suspension-corrected rigid fork with all the braze-ons under the sun. Want to build a 29er with road gearing, smooth tires, fenders and cantilever brakes? Go for it. Want disc brakes, a 100mm suspension fork, a Rohloff and fat rubber? That works too. Maybe build it up, enjoy it for a while, and then build it up with new stuff!
Surly Ice Cream Truck Frameset
$825.00
Surly's Ice Cream Truck turns up the volume on fat. With unmatched traction and float courtesy of super wide tires (up to 4.8-inches wide!), and the flickable geometry of your favorite trail bike, this fatty feels frisky, limber, and ready for action. The symmetrically spaced 190mm rear end uses Surly's Modular Dropout system for an array of rear axles choices. 197mm thru-axle? 190mm geared? Singlespeed? All equally plausible possibilities with the Ice Cream Truck. A 44mm headtube provides fork options, and the frameset ships with a suspension-corrected, 150mm fork with a 15mm thru-axle. Surly's proprietary 4130 chromoly steel and corrosion-fighting ED coating add a hefty dose of tough to this bike. Now, where do you want to ride your Ice Cream Truck?
Surly Wednesday Frameset
$650.00
Wednesday is a frame with a decade of Surly's Omniterra design experience distilled into one steel package. Wednesday can ride over the same type of pretty much anything all of their other Omniterra bikes can, but they borrowed elements from both their Trail and Touring categories to create an Omniterra ride that can truly handle anything you want to attempt. Want to point the thing down a mountain and roll those dice? Wednesday has geometry spry enough to get you through the techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish when you have to ride back to the top. It also has the chops for any sort of expedition you may want to undertake. It has plenty of bottle mounts; triple bottle bosses on both fork legs and the down tube; standard bottle mounts on the seat tube and underside of the down tube; plus rack mounts on the frame and fork and fender eyelets on the dropouts, along with barrel bosses on the crown, fork legs and mid-blade, thru-blade eyelets on the fork as well. It also has internal dropper post routing and Surly Trip Guides to manage all the housing and cables on your frame with style. Wednesday also has its very own dropout design as well – a rear-facing, slotted dropout that can use either 10mm or 12mm axles and exit rearward or vertically. They’re cast steel and spaced at 170/177mm. Wednesday gives you a lot of options in the tire clearance category. In the full-forward, short chainstay position you can run 26 x 3.8? tires on 80mm rims and in the full-rearward, longer chainstay position you get the option of 26 x 4.6? tires on an 80mm rim. Wednesday is made out of Surly's own proprietary 4130 CroMoly steel and is ED coated for extra protection from the elements.
Surly Wednesday Frameset
$650.00
The Wednesday is the result of over a decade of Omniterra design experience distilled into one steel package. It can easily ride over or through most anything our other Omniterra bikes can and then some. With the Wednesday Frameset, Surly borrowed elements from some of their Trail and Touring models to create an Omniterra whip that can truly handle anything you want to attempt. Want to point it down the side of mountain? Go ahead, roll those dice. And if you make it to the bottom, you’ll be able to ride back to the top for round two. Wednesday’s geometry is spry enough to get you through techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish on terrain-crawling stuff. While Wednesday is plenty confident on terrifying terrain, it also has the chops for any sort of expedition you may want to undertake. Surly gave it all the necessary braze-ons and mounts for whatever accoutrements you feel necessary in your travels. Racks? Front and rear, friend. Fenders? You got it. Bottle mounts? How does triple bottle bosses on both fork legs and the down tube, and two sets of standard mounts on the main triangle grab you? They even gave Wednesday internal routing for a dropper post and Surly Trip Guides to keep everything nice and neat and free of rat’s nests. In the dropout department, Wednesday uses a cast steel, rear-facing, slotted dropout that can exit either rearward or vertically. They’re compatible with either 10mm or 12mm axles and are spaced at 170/177mm.
Surly Big Dummy Frameset
$999.00
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 Moonlander Frameset
$675.00
If you ever looked at miles of mostly unrideable landscape and thought, "hmmm, I wish I could ride over that," then Surly's Moonlander is the perfect frameset for building your ultimate bike. Surly handcrafts this fine frame and fork with reliable, great-riding butted chromoly and provides the clearances for 26-inch wheels with up to humongously wide 4.7-inch tires. You also get frame reinforcements in all the right places and all the braze-ons and details needed so that you can handcraft your dream fat bike.
Surly Troll Frameset
$599.00 - $650.00
Off-road touring can be a zesty enterprise, but it’s not without its perils. Bicycles are simple machines that are extremely efficient, but all simple machines carry along with them the chance of breaking down. This efficiency can get you in trouble if your bike decides to break down far away from the comforts of your parent’s basement. If you’re going to ride your bicycles where no one can see, you better take gear that’s up to the task. Troll is up to the task. Surly's Troll was once a simple mountain bike frame with a few extras that made it nice for touring. The Troll has evolved into a frame that has been pushed deeper into the category of off-road touring. Its geometry is no longer suspension corrected, which gives it more room for a larger frame bag. The chainstay yoke has been redesigned to be fully compatible with 26+ tires and comes with the always-comfy Jones Loop bar. The dropouts still allow you to run disc brakes, fenders, a Rohloff hub, and racks simultaneously. It also comes with more braze-ons than you thought possible – there are four triple bottle mounts on the fork alone (don’t get excited, you can only run one Anything Cage per fork leg), as well as two more triple bottle mounts on the down tube. Troll is a bike that has one purpose – and that purpose is to carry you as far away from society as possible.
Surly Karate Monkey Singlespeed Frameset
$625.00
The Karate Monkey was one of the first production 29ers. It put the 29? platform in front of a lot of people at a price within reach of many a bike nerd. Since then, 29” has become a full-blown category, with entire bike companies dedicated to the platform. In contrast to the old standard 26” wheels, 29? wheels have unique benefits: delivering increased traction, smoothing out terrain, carrying inertia, and generally fitting tall riders better. With a frame and fork made of custom-designed Surly CroMoly “’Natch” steel, the Karate Monkey delivers a resilient, lively, durable ride. The Karate Monkey frame has recently been updated to include features like internal dropper post routing, a new tubeset that uses the same trumpet tubes found on their Instigator 2.0, and a slight tweak in geometry that is more progressive and trail oriented. The Karate Monkey uses a horizontal dropout with a derailleur hanger spaced to what we call Gnot-Boost spacing. 10 x 135mm QR, 12 x 142, or 12 x 148 Boost will all work in the Karate Monkey frame. The frame uses a 44mm headtube for broad fork compatibility and is ED coated for an added layer of internal protection. The Karate Monkey SS is the sensei for all of your single speed sensations.
Surly Ogre Frameset
$650.00
If you’re like us, your bike needs will likely change by the day, week, month, or year. Surly's Ogre can get you to your job during the week, then way out of town on the weekend. The latest version of the Ogre has received some fantastic updates, including horizontal slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefier tire clearance — all in a 29er/27.5+ platform. Ride it any day of the week; it’s not sluggish on pavement or gravel and can also hold its own on singletrack. - Gnot-Boost spacing allows the use of 135mm QR hub, 142 x 12mm thru-axle, or 148 x 12mm Boost hubs. - Full-length Surly Trip Guide housing line guides for derailleurs and brakes - Two sets of bottle cage mounts - Disc and rim brake compatible with removable post cantilever pivots - Upper seatstay threaded barrels with mid- and low-blade fully threaded through-blade fork eyelets - Threaded holes for racks, fenders, and trailer mounting nuts - Rohloff OEM2 axle plate mounting slot - Tire clearance for 29 x 2.5” or 27.5 x 3”
Surly ECR Frameset
$725.00
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 they're 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.

Fat tires mean smooth-rolling traction, stability to spare, and a touch of suspension over the roughest terrain. On top of all that, frame eyelets galore are just waiting for racks, fenders, and whatever else to make this your pedal-powered escape pod.

Surly Krampus Frameset
$625.00
Surly's Krampus rolls fast, holds speed, and devours corners. It's designed for 29 x 3-inch tires, offering increased traction, incredible float, huge rollover, and low-fi suspension to take your trail ride to new heights of fun. Surly built this frame and fork out of tapered and butted chromoly and gave the frame a long top tube and short chainstays, so it's playful, smooth, versatile, and durable. Boost front spacing keeps you current with the latest MTB tech, and, "Gnot Boost," rear spacing means you can run any the rear hub you want: 135 x 10 QR, 142 x 12mm, or 148 x 12mm thru axles. This frameset also offers internal dropper post routing so you're granted a license to get rowdy, which you really can't help but do on a Krampus.
