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's Krampus rolls fast, holds speed, and devours corners. Surly built its Boosted 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. The 29 x 3-inch Dirt Wizard tires on 40mm Alex rims take your trail ride to new heights of fun. These big tires offer increased traction, incredible float, and reduce the need for suspension because the large volume is plenty to smooth the trail. You'll also get a SRAM NX 1x drivetrain, Answer Pro Taper bars, and SRAM Level hydraulic brakes to make you the new master of terrain that used to be out of bounds.

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
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.
When your bike touring route takes you over the river and through the woods with a quick jaunt through town for supplies, you can't beat the versatility and smooth riding characteristics of Surly's new Bridge Club. First off, it's a Surly so you know the 'Natch chromoly steel frame and fork are built to handle your entire kit and caboodle, and thanks to the typical overabundance of rack and cage provisions you can mount your gear via traditional racks and panniers, go full bikepacking-style, or mix-up your favorite combo of the two. The Bridge Club rolls on plump 27.5 x 2.4-inch WTB Riddler tires for a blend of low rolling resistance on smooth pavement and confident handling on forest trails. You can also run up to a 2.8-inch wide tire for more flotation, or swap-in a 700c wheel and tire combo if your route includes a lot of on-road riding. A dependable 2x10 drivetrain ensures you'll never run out of gears as you make the push up long climbs, and mechanical disc brakes offer worry-free performance to keep you safe no matter what the weather brings. And, thanks to fully housed cabling and front and rear fender mounts, you can splash through soggy days with a smile. A comfortable Salsa Bend flat bar and WTB Volt saddle complete this relaxed all-terrain tourer.
The Surly Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out.

Singlespeeding is an integral part of Surly’s DNA, and the Lowside continues the tradition, by taking a simpler approach to trail riding. - 100% Surly 4130 chromoly frame, main triangle is double-butted; 1 1/8" threadless chromoly fork - Singlespeed "specific" (derailleur hanger: yes; Trip Guides: no) - Dropper post routing - Gnot-Boost rear spacing - Front and rear thru-axles - 26 x 3" or 27.5 x 2.8" tire clearance

The venerable Karate Monkey. When it comes to mountain riding, this bike brings everything you need to the experience and more. It's shod with 27.5 x 3.00 terrain-clawing Dirt Wizards for max traction on singletrack thanks to an aggressive tread pattern and cushy, wide footprint. But there's more to this agile trail runner's set of shoes — thanks to generous frame clearance, you can drop a set of 29-inch wheels in with up to a 2.50-inch tire if you desire something with less bite and similar roll-over capabilities. And, with Surly's Gnot Boost rear dropout spacing, you can comfortably run any kind of mountain bike hub: 10 x 135mm QR, 12 x 142mm, or 12 x 148mm Boost will all work in the Karate Monkey frame.

Wednesday is a frame with a decade of Surly's Omniterra design experience distilled into one steel package.

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.

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.
