We think by now, most of you get what Straggler is. It’s a madly versatile bike that can be used for most types of riding and riding surfaces. Better still is that you now have the option of 650b wheel size. 650b wheels were popular for a long time many years ago on ‘Constructeur’ style bicycles and we all know how real stuff was back in the day…650b wheels strike a nice balance between the benefits of both 26” and 700c sizes. The smaller wheel allows smaller riders to fit well on smaller frames, produces a stronger wheel, makes fitting big-ass tires easier and are more agile than their larger counterparts. Straggler has disc caliper mounts instead of rim brake studs. It’ll accept rotors up to 160mm. The rear dropouts are unique, too. They’re a partially closed horizontal design that accommodates singlespeed or geared drivetrains. They feature stop screws that thread in from the rear to further secure the wheel and to position the rear wheel for optimal shifting, plus a forward-mounted stop screw on the drive side to keep the wheel from slipping forward under the force of your gargantuan legs. The rear dropouts are spaced 135mm instead of 132.5mm like the Cross-Check simply because there are far more options for disc hubs in this spacing. Straggler 650b has braze-ons for fenders, racks and bottle cages. The geometry is slightly different, with angles and tube lengths very close but not identical to the Cross-Check, but like the Cross-Check it’s ready to take you just about anywhere. It’s a day tripper and a weekender. It’s a ‘rough road’ road bike. It’s a cyclocross bike with no pretense about racing. It’s a utilitarian townie. It’s a light-duty touring bike. It’s an all-weather commuter. And when you get tired of one set up, you can swap parts around and turn it into something else. We think that’s pretty neat.

Surly's Stainless Steel Chainrings last longer than their aluminum brethern because the 304 grade metal they use is 35% stronger. The rings aren't pinned or ramped so when one side starts to wear you can flip it around and pedal some more! They work great with singlespeed, fixed, and 1x9 applications, and the teeth are 2.2 - 2.3mm thick so they work well with wider chains.

Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. Your BMX Bike All Grown Up Lowside is like the grownup version of the bike you rode when you were a kid and still had hopes and dreams and some semblance of ambition. It's just as happy riding singletrack as it is parked outside your favorite drinking establishment. Lowside is a single speed mountain bike. Singlespeeding has been a part of Surly's DNA since day one when we launched the 1x1 Rat Ride. After a lot of Homie Fall Fests and more feats of strength than we can recall, we decided to discontinue it a couple years back. Lowside picks up right where the 1x1 left off. "Some have dubbed the Lowside the ultimate pub cruiser." - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Spec'd in alternating years with 26 x 3" or 27.5 x 2.8" tires, the Lowside remains capable of running either option

Surly's Junk Straps can secure almost anything to almost anything else. Essentially an extra long toe strap, they're easy to use and store. And, trust us, these handy straps will get used often.

A class-leading touring bike, the newly redesigned Disc Trucker provides versatility and dependability on the daily commute or trans-continental excursion. Fork blade three-pack mounts enable you to attach and haul even more stuff, and the frame features a low bottom bracket and long chainstays for comfort and stability while loaded down. With increased stack height and improved standover clearance, plus ample space for larger tires and fenders, it’s designed to go the distance. Introduced in 2012, the Disc Trucker is widely considered one of the best-in-class touring bicycles available today. Truly at home on the road, it features updated geo and modern component compatibility, along with versatile mounting options that make it ideal for daily commutes and months-long disappearing acts alike. Built from Surly’s proprietary, touring-compliant 'Natch tubesets, updates to the Disc Trucker include a shortened seat tube and slightly sloped top tube for better stand-over clearance, plus an increased stack height for a more relaxed riding position. Shortened chainstays offer improved stiffness and maneuverability around corners, while 12mm thru-axles provide a stiffer feel and greater stability when fully loaded. To ensure the Disc Trucker continues to exceed expectations in terms of compatibility with modern product standards, its dropouts have been redesigned to accommodate flat-mount disc brakes and captured thru-axles. An updated fork incorporates dynamo routing and three-pack mounts for even more mounting options. Additionally, the 700c platform now offers clearance for 47mm tires for greater flexibility in tire options. - 100% Chromoly steel frame and fork; double-butted main triangle and E.D. coating for increased frame life - Braze-ons for fenders, racks, and almost anything else you might want to stick on your bike, plus spare spoke holders for when the road gets rough - Fork blade three-pack mounts for even more mounting options, plus routing for Dynamo hubs - Redesigned front and rear dropouts to accommodate captured 12mm thru-axles and flat-mount disc brakes - Clearance for 700c x 47 tires with or without fenders

Hurdy Gurdy is another nifty device that keeps a rear wheel from slipping forward in the dropout under pedal load. It's designed for the Cross-Check's semi-horizontal front-loading dropouts, and will also work on many other similar dropouts. Hurdy Gurdy is investment cast of stainless steel for durability and good looks, and shares many of Tuggnut's design features. Its two axle holes allow for a wide variety of fore/aft wheel positions, it will work with standard QRs, bolted axles, and nutted axles up to 10mm.

The Grappler is Surly's dedicated drop-bar trail bike. With mountain geo designed around a comfortable, confident drop-bar hand position, it's lively and responsive on single track, double track, and other degraded surfaces. Ready to haul essential gear for all-day dirt rides and quick bikepacking excursions, captured thru-axles front and rear provide ideal stiffness and handling. Built around 27.5" wheels and compatible with internally geared hub and single-speed setups, Surly's tried-and-true Gnot-Boost spacing allows riders to run 142mm or 148mm rear hubs. - 100% Surly Chromoly steel frame and fork, featuring Surly's proprietary 'Natch tubing, double-butted main triangle, 1-1/8" headtube, non-suspension corrected. - Horizontal-slotted dropout, Surly Gnot-Boost spacing. - Seat stay mounted bottle bosses on all sizes except XS, plus three-pack mounts at the top and bottom of the down tube and stealth dropper post routing. - E.D. coated frame for increased life expectancy. - 27.5 x 2.8" tire clearance (with or without fenders).

Bridge Club is a highly versatile touring bike that perfectly hits the sweet spot spanning on- and off-road excursions. Bridge Club is for those multi-surface outings — planned or unplanned. We've all run out the clock on a dirt tour and had to add in some paved shortcuts. Conversely, when you’re feeling a little zesty on your next road tour, Bridge Club is ready for reroutes through the woods. Some people hear "bike touring" and immediately think of long-forgotten stretches of highway, small-town oddities, and roadside attractions. Some instantly recall desolate stretches of desert dirt roads or lush green forest trails. With Bridge Club, you can have your dessert and eat it too! - Ultra-focused on simplicity, it only has the barnacles that matter most to the discerning bike tourist - Two build kit options: Pavement (700c) and Off-Road (27.5-inch) - Run racks and panniers, framebags, or all of the above - Disc brake-specific, single position, vertical rear dropout makes it less intimidating than other bikes in the category - Clearance for 700 x 47mm tires (with or without fenders), 27.5 x 2.80 tires (27.5 x 2.60 with fenders), and 26 x 3.0 tires (26 x 2.80 with fenders)

As the first "plus" bike to hit the market, Krampus changed the way many people approach trail riding. It's shown people the light of how high-volume, large-diameter tires can vastly improve the ride experience. It's also done a bang-up job dispelling the myth that big tires make you slow. Krampus is kind of like the opposite of a mullet: long in the front and short in the rear. With a long toptube and compact chainstays, it takes trail-shredding abilities to the next level. A mullet may be business in the front, party in the back but Krampus makes partying its business. - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension-corrected fork - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Clearance for 29 x 3" tires

Straggler is a bikepacking-inspired road/gravel bike mostly at home on pavement but ready for trail duty when called. Born on Gravel. Raised on Pavement Straggler is tuned for cross-over exploration on a wide variety of terrain conditions. It's a day-tripper and a weekender. It's a "rough road" road bike, a cyclocross bike with no pretense about racing, a utilitarian townie, a light-duty touring bike and an all-weather commuter. It's a steel gravel bicycle that thrives on the road. Think of it as a "mountain biker's road bike." If you only have room for one bike in your life, Straggler can (and should) be your one and only. Straggler's capabilities go well beyond asphalt. It also lends itself well to light touring setups. We're talking frame bags, seat bags, and "credit card touring" rather than full-blown touring. Straggler also handles our 8- and 24-Pack Racks well, so you have some heavier-duty loading options. - Accommodations for racks and fenders - Forward-exiting horizontal dropouts for singlespeed compatibility and wheelbase adjustability - Clearance for 650B x 41mm tires with fenders!

You can proudly display these Surly Logo Stickers just about anywhere they'll fit. They comes in three sizes to meet a wide range of sticking needs.

As you must know by now, wool resists odor. We have found that is a good feature in a sock. They also wick and insulate better than cotton or all synthetic, so you can wear them comfortably in a pretty wide range of climates. Surly Socks are made by DeFeet using Merino wool and a small amount of synthetic material for increased durability. These ones here are 5" tall.

Midnight Special is a road plus bike designed to provide comfort and speed on those all-day rides that extend well beyond fresh pavement. Midnight Special shines on pot-holed, deteriorating pavement and the occasional long stretch of gravel. Its 650B road plus tires eat up road chatter and absorb all the bumps in the road like the champion it was designed to be. When it comes to road bikes, we just want to toss a few bananas into our pockets and see where the road takes us. We seek out varied surfaces on our rides and frequently go from pavement to gravel to worse pavement. Midnight Special allows us to accomplish all of that quite comfortably. - Higher volume tires allow better fine tuning of tire pressure on varying surfaces and create a wider contact patch for increased traction - Modern road standards like flat-mount disc brakes, 12mm front and rear thru-axles, and a 44mm head tube - Clearance for 650B x 60mm or 700c x 42mm tires without fenders (650B x 50mm or 700c x 38mm with fenders)

The 12mm slotted MDS dropout is the newest chip for Surly's MDS equipped trail frames. You like chips, don't you? The 12mm slotted dropout chip uses a standard derailleur mount for maximum compatibility and is made of cast and machined 6061-T6 aluminum, with a fender eyelet. What's the coolest part about the 12mm slotted MDS chip, you ask? The fact that it also has the capability to run a 12 x 142mm thru-axle in a single speed configuration. This is good news because single speeds are good news. When you get an MDS equipped frame you're getting the option to set it up however you want. You can run a 142 x 12mm thru-axle rear end with a direct mount Shimano hanger, standard 135mm QR or The Mighty Singlespeed. The way this will work is that Surly complete bikes that feature the MDS will ship with whatever chip is compatible with derailleur spec. For instance, the complete Instigator 2.0 ships with the 142 x 12mm thru-axle Shimano chip. If you want to change it to a singlespeed later (and why wouldn't you?), all you have to do is get the SS chip. Frames will ship with all three MDS chips so pick your poison. The 142 x 12mm and 135mm QR chips are made of cast and machined 6061-T6 aluminum and The Mighty Singlespeed chip is 304 stainless steel, because the two words 'aluminum' and 'singlespeed' should never be too close to each other. Bad things can happen…. As you can see, the MDS gives you not just different build options, it lets you use a more varied selection of parts for your frame up builds. The MDS is featured on most of our trail bikes. That's right: Krampus Ops, Karate Monkey Ops, Instigator 2.0 and Ice Cream Truck frames all sport these puppies.

Karate Monkey is a highly versatile trail bike that plays the part of 29er and 27.5+ equally well. Karate Monkey delivers a resilient, lively ride on all sorts of gnarly terrain. Its frame is a highly-versatile canvas for whatever dirty masterpiece your brain cooks up. According to our computing machine (Thor) it can be set up in approximately 487 different configurations. Originally designed as a 29er (and the frame that helped spark the 29" wheel movement), the latest Karate Monkey is designed to perform just as admirably as a 27.5+ rig as well. This allows you to pick your poison — provided your poison is having a really great time while permanently donning a huge grin, of course. - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension corrected fork - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Clearance for 29" x 2.5" or 27.5" x 3" tires
