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 - Recommended rim width: 23 – 30mm

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 Ted Trailer is brilliantly engineered to carry almost everything! This seriously stout workhorse is built from chromoly with stainless-steel hardware for excellent durability and it rolls on quality 16-inch wheels and tires. There are even fenders. The trailer sits perfectly level as you ride, so you can haul longer items that extend off the back. You can tote up to 300 pounds of whatever on this bad boy! So go ahead, run all your errands by bike — you'll be smiling when you get back home. Please note that the required Surly hitch for this trailer is sold separately.

This beauty here was designed alongside Surly's Midnight Special frame. In an effort to shed a few grams (it's for a road bike after all), they opted to utilize a unicrown design rather than a lugged one. In addition to the weight savings, it also looks really nice — don't you think? Like the Midnight Special frame, this fork is equipped with modern road standards like flat mount disc brakes and a 12 x 100mm thru-axle. For increased versatility, it has braze-ons for fenders and racks (including mid-blade!). - 100% CroMoly construction, fully brazed crown - Mid-blade thru-blade eyelets - Rack and fender eyelets at the dropout - 12 x 100mm thru-axle - Clearance for 27.5 x 2.32 or 700c x 42mm tires

So what is this Straggler anyway? The easy answer is to say that we added disc brakes to a Cross-Check and this is close to accurate. People have asked us to make a disc version of our highly versatile Cross-Check for a long time now and almost everything about the two are very similar. Straggler is slightly different, though. The most obvious difference of course is that the 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 shares all of the Cross-Check’s braze-ons for fenders, racks and bottle cages. The Straggler’s 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.

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

Steel Commuter and Gravel Bike Preamble is a hard-boiled steel commuter built for comfort, durability, and buffoonery on pavement and gravel. Nothing More is Needed. Nothing Less Will Do. The challenge was thus: Build a serious steel bike and give it only the attributes that matter most. Make it quick and comfortable on pavement, as well as confident and compliant on degraded surfaces. What the Enginerds put forth is Preamble, a pavement and gravel utility worker that proves you don't need to cut corners or clip coupons to make a more affordable steel bike. You just need to keep shit simple. Preamble can run racks and fenders and carry a couple water bottles. Surly was raised on stealing basic cable, after all. Smooth and efficient on asphalt, Preamble's double-butted main triangle provides a resplendent ride feel and withstands abuse from life's inevitable potholes. Make it your own with flat bars, drop bars, a basket, or bags. On the road to steel euphoria, Preamble is the gateway drug.

Breaking the Mold with a 29er Bike 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.
