Surly Pugsley
$1,900.00
The Surly Pugsley may be the original fat bike, but this one is far from the original. Previously a great all-around fat bike, the Pugsley has been redesigned to be an ideal off-road touring and exploration rig. Surly lengthened the chainstays 12mm for stability when loaded and so your heels float effortlessly past panniers. The tweaked rear rack mounts on the dropouts let you center your rack over the wheel, despite the offset rear triangle. Those dropouts will take a 142x12mm thru axle if that's your schtick, but this rig comes with a 135mm QR hub, snug as a bug with a pair of adapter washers. Pugsley brings back the 135mm-spaced offset fork, so you can run a front wheel with a spare cog or freewheel as a bail-out option to swap with the rear if your internally-geared hub freezes up in neutral or you smash your derailleur having too much fun. A plethora of three-pack mounts give you gear-hauling options aplenty, and a Surly Moloko Bar gives your hands damn near as many options as well, so they stay clappably happy even on your longest, story-generating adventures.
Surly Karate Monkey
$1,550.00
Years ago the Karate Monkey helped start the 29-inch 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-inch wheel, yet you get all the traction and floatation benefits of extra-wide knobbies. And that's just the tires. The Karate Monkey frame has recently gotten a makeover that includes the addition of features like internal dropper post routing, a new tubeset that uses the same trumpet tubes found on Surly's 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-inch 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. - 100% Surly 4130 chromoly steel frame and fork; double-butted main triangle and 44mm headtube - Adjustable rear dropouts with 145mm Gnot-Boost spacing. Works with 142, 148 12mm thru, as well as 135mm w/ 10/12 washer - Internal dropper seatpost routing with 30.9mm seat tube ID - Clearance for 29 x 2.55 or 27.5 x 3 tires

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 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 Karate Monkey 27.5+ Frameset
$675.00
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.

Surly Troll Frameset
$650.00 - $675.00
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 Krampus Frameset
$675.00
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.
