Surly Krampus Frame Stickers/Decals - For repair, repaint, or whatever - Dry transfer style - Headbadge included

Our family of Dirt Wizards is highly-focused – one might even say spellbound – on providing traction and control on the kinds of surfaces where nary traction nor control are to be found. Its tread is comprised of a dual row of aggressive, trail-gobbling, beveled knobs in the center and well-spaced, siped knobs to dig into loose corners. Designed to work on 50mm rims, Dirt Wizards are tall and wide, providing next-level traction and cushioning. The casings have been designed to be flexible and responsive, yet durable and supportive. Minimum rim size for these naughty little wizards is a 35mm outer rim width. - Folding bead - Casing: 60 TPI - Max pressure: 30psi

This expedition-worthy rack is made from 4130 chromoly, so it's tough, light and easily repairable in the field. It's also height-adjustable, so you can get your center of gravity as low as possible for a stable ride. The provided stainless steel hardware enables you to attach your rack to virtually any frame with 26-inch, 700c and 29-inch wheels. And, it hauls up to 80 pounds of gear and is powder-coated to protect it from the elements.

Machined from heat-treated, chrome-plated chromoly, these seriously tough cogs will hold up to massive track sprints and crazy skid-stops. Surly's Track Cogs are strong, shiny and they come in two widths and sizes from 13T to 22T so you can select the perfect gear.

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 2.1mm thick so they work well with 9-speed chains.

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

Single chainring drive train setups are all the rage these days. With the introduction of exceedingly wide range 10- and 11-speed cassettes, the need for two chainrings has become a thing of the past. But when you only have one chainring, the only thing standing between you and a long walk back to the trailhead is you making sure you don't destroy your one chainring. That's why Surly made a chainring guard to fit O.D. cranks. It is made of aluminum and will take the hit for your chainring. It comes in 5 bolt, 94mm BCD and was designed to protect 22t – 30t rings.

Build your singlespeed or fixie bike around Surly's Ultra New Roadie Rear Hub. This gorgeous hunk of aluminum has the capability you need and reliable sealed bearings, too! It sports threads for a track cog and lockring on one side and a freewheel on the other so you can decide how you want to roll. Plus, this hub's 130mm width fits most road frames and the hollow chromoly axle provides a flex-free ride as well as simple quick release skewer compatibility.

Offering a variety of hand positions for comfort over the long haul, it also features 30mm of rise for a more upright and relaxed riding position. With a clean aesthetic, it’s a great option for taller riders looking for more rise and for bikes with a low-cut steer tube. - Lightweight, aluminum construction - Available in various widths - 31.8mm clamp diameter

When you’re out on a ride the last thing you want is to be limited by your tires in any way. Our ExtraTerrestrial Tires were designed to let you ride without limits by simply following the only tenets we have for tire design: they’re high volume and they kick ass. The ExtraTerrestrial tire was meant to serve as a heavy-duty off-road touring tire that shines on hardpack surfaces. It uses a nylon breaker in the sidewalls for cut protection, a molded pattern for anti-cut propagation, and a Kevlar cap under the tread to protect against flats. The ET Tire uses a distinctly directional tread pattern and its width yields more traction than you might expect from a tire with such little rolling resistance. The tread is low profile with a file tread in between tread blocks. The ExtraTerrestrial tire has enough width and traction for the soft stuff and won’t bog you down on smooth or hard surfaces. - Folding bead - Casing: 60 TPI

Like its QR cousin, the Disc Trucker Thru-Axle Fork is designed to mount racks and fenders and haul your worldly possessions. It's also got modern touches like dynamo routing, compatibility with flat-mount disc brakes, and three-pack mounts on both fork blades to satisfy your deepest cargo desires. Captured 12mm thru-axles make tool-free removal and installation possible. Offered in 26" and 700c wheel sizes, the Thru-Axle fork clears 26 x 2.1" or 700c x 47mm tires. With a 1-1/8" steerer, it's powder-coated and constructed using the same Chromoly steel as all our other frames and forks. Why? Because we swore a blood oath to steel and we intend to keep it. Note: The Disc Trucker TA Fork is designed to pair best with second-generation Disc Trucker models—those first released in 2020. Defy this guidance at your own peril. 26 Inch - Axle-to-crown: 376mm - Offset: 45mm - Steerer: 42–54cm frames = 300mm, 1-1/8" straight - 56–62cm frames = 400mm, 1-1/8" straight - Tire Clearance: 26 x 2.1" (with or without fenders) 700c - Axle-to-crown: 390mm - Offset: 45mm - Steerer: 56–64cm frames = 350mm, 1-1/8" straight - Tire Clearance: 700c x 47mm (with or without fenders)

Designed for Surly's Krampus frame, this fork has quick-release dropouts spaced at 100mm and clearance for a 3-inch tire on a 50mm rim. To accommodate such big tires it's got a longer axle-to-crown measurement than the Ogre or Karate Monkey forks, making it a perfect rigid fork option for lots of 29ers out there. The Krampus fork's blades were designed and manufactured specifically to play well with the unique forces such a long fork with big tires will encounter, and the steer tube is standard 1-1/8-inch threadless. It has line guides for a disc brake line as well as thru-blade eyelets and Three-Pack bosses on both fork legs. - Axle-to-crown: 483mm - Offset: 47mm - Steerer: 260mm - Tire Clearance: 29 x 3" - Weight: 1133g uncut

Surly's Ultra New Disc Rear Hub is just the thing for singlespeed fanatics and one-gear mountain riders. This gorgeous hunk of aluminum boasts reliable sealed bearings and a 6-bolt disc attachment on one side and threads for a singlespeed freewheel (or fixed cog) on the other. A hollow axle lets you choose how to secure it to your dropouts. You have choice between the included fixing bolts or a quick release skewer (sold separately). And, that aforementioned chromoly axle is flex-free to take all the abuse you can dish out, and then some!

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 Surly Corner Bar is for off-road riders who want to give drop bars a try without swapping out the drivetrain and brake levers on their current mountain setup.
