Surly

This fine pair of Surly 10/12 Adapter Washers is designed to adapt any 135, 170, or 190mm O.L.D. QR axle hub with a 142, 177 or 197mm spaced thru-axle frame. Make sure the QR axle on your wheel is the right length for the frame spacing. For instance: 190mm OLD QR goes with 197mm thru-axle spacing.

Whether for derailleur clamp clearance, tire clearance, or personal preference, sometimes it can be advantageous to run the wheel further back in the dropouts. Monkey Nuts install into Surly horizontal dropouts to make spacing the wheel back easy. There are 3 different sets depending on the type of dropout and axle configuration the dropout is intended for. Simply select the correct version of Monkey Nut, install it into the frame, and slam the wheel all the way forward. Bang, done.

Surly OD Bottom Brackets - PF cups are 41mm in diameter - Bearing I.D. is 24mm - OD bottom bracket comes with telescoping center sleeve for added durability - High quality double labyrinth sealed stainless Enduro bearings with corrosion resistant coating - 3 additional 1mm spacers are provided to help with chain line and crank arm clearance

Rated fully KICKASS by a very authoritative entity who will remain unnamed, Surly's cast and polished stainless steel clamps won't rust or chip paint because they can't (even the black ones!). They're shiny! They look good! And most importantly, they deliver the clampability seatposts crave.

Surly Rim Strips have one job and they do it well. They cover the cutouts in your rim and — if you're running a tube — they protect it from spoke heads and other sharp matter (okay, so maybe they have TWO jobs but they do them both really well.) Rim strips are crucial and should be used with all Surly rims. Ours come in an array of colors so you can really "express yourself." Surly Rim strips are available in two different materials: PVC and Nylon. PVC is great if you plan on only running tubes. However, if there's any part of you that wants to try this tubeless thing you've been hearing about, Nylon strips are just the ticket. They're thinner and offer minimal stretch so they stay put and lay nicely inside the rim to provide a secure seal. Plus, they're lighter which we all know means you'll go faster… maybe.

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.

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. - 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 26 x 2.1" tires with or without 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

The Karate Monkey features updated, progressive trail geometry, our custom trumpet tubeset, and Surly's Gnot-Boost rear dropout system. Available in a variety of colors, with multiple drivetrain and wheel size configurations.

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 700c x 41mm tires with fenders!

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

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 hubs 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).

Surly's MWOD Inner Chainrings are made from stainless steel for extreme durability. These rings are compatible with Surly's MWOD cranks.

Surly Monkey Nuts v3 Dropout Spacers let you keep that rear wheel nice 'n' perpendicular in those horizontal dropouts, no matter how much of a diesel you are. So go ahead, stomp on the pedals and let the rooster tails fly. They're sold individually because most folks only need one on the drive side.

With Wednesday, we borrowed elements from some of our Trail and Touring models to create a versatile fat tire trail 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.

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

Suitable as a tourniquet or stylish headband in a pinch, the Whip Lash's primary function is to help you attach whatever needs attaching to your bicycle frame. Available in a multi-pack that includes two 550mm lashes and one 695mm lash, the Whip Lash's potential is limited only by your imagination. You could use one to strap your beverage to the down tube when the trail says you ought to keep your hands on the bars. Or you could use another to fix your fishing gear to the top tube when rack space is maxed out. Whatever you get into on or off the bike, they're handy to have around because they're light, compact, and easy to use. Rubberized on one side to keep your stuff from slipping around, the Whip Lash's trimmable design features nylon construction and a simple hook-and-loop style closure.
