$30.00 - $35.00
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 MDS Dropout Chips
$33.50 - $49.99
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.
Surly Cassette Cog
$35.00
Pair this cog with your Shimano-compatible rear hub, spacers and a lockring (sold separately) and discover the joy and simplicity of a singlespeed without the cost of a new wheel. Machined from heat-treated chromoly and then chrome plated, these seriously tough cogs are strong, shiny and they come in sizes from 13T to 22T so you can pick the perfect gear.
Surly Dingle Cog
$44.99
If you love the feel and simplicity of a fixed gear, but crave a bit more versatility from your steed, the Surly Dingle Cog has just what you need.

Suddenly your fixed gear is a two-speed so you can tackle varied terrain with more ease.

Surly Sunrise Handlebars
$65.00
In today’s fast-paced world of riseless flat bars and far-too-aggressive-for-our-liking cockpits, Surly harkens back to simpler times. They wanted a handlebar that would suffice for a relaxed cruise to a favorite windowless bar, but would also be suitable should a person decide to take the long way home. The Sunrise Bar is a cruiser bar, a trail bar, and a BMX bar all rolled into one. It has a 22.2mm clamp diameter, but Surly included some Problem Solvers shims so you can mount it up to your fancy 31.8mm stem. Material: CroMoly steel Clamp diameter: 22.2mm; Includes shims for 31.8mm clamp Width: 820mm; Can be cut to 720mm Rise: 83mm Sweep Angle: 14.7 degree backsweep, 6.7 degree upsweep Weight: 778g including shims Color: Black
Surly Dirt Wizard 29-inch Tubeless Ready
$79.99
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
Surly MWOD Chainrings
$92.99 - $93.00
Trust Surly to come up with a reasonable solution to a bizarre problem. The Surly MWOD chainring set moves a bike's chainline away from the spinning tire allowing for the use of super wide tires on extra wide rims. The genius part is that it doesn't increase the Q factor (a.k.a. width of the bottom bracket) and keeps the low gears necessary for pedaling bikes with monster tires. The chainring set bolts directly to Mr. Whirly cranks and is available in two sizes.
Surly 1x1 Fork
$99.99
The 1x1 fork is designed for use with Surly's 1x1 frame. It uses 51mm I.S. disc caliper mounts, line guides, and it is corrected for frames designed for 100mm suspension forks. The 1x1 fork is triple butted and can fit real big tires…you can stuff 2.7-inch tires between the blades and have room to spare. Made from 4130 CroMoly tubing, with 1-1/8" threadless steerer and powdercoated black.
Surly Ogre Fork
$109.99
Surly's Ogre Fork is perfect for replacing 80mm-travel suspension forks on 29-inch wheel bikes or for building a custom 29er. This sweet fork features large-diameter, thin-wall chromoly blades that taper for a smooth and supple ride. And, it's got removable rim-brake posts, disc-brake tabs, fender mounts, standard and low-rider rack mounts and a tough powdercoat finish because it's awesome.
Surly Front Rack
$145.00
Surly Racks are well-thought-out, durable, expedition-worthy racks that work with most panniers. While their racks aren't limited solely to heavy duty touring, that is what they were designed for. When you're out on the road, the best option is to never ever have anything ever go wrong ever. Right? That's never a guarantee though; so having something that you can repair if it does break can be pretty clutch. Thus, the main bodies of Surly's front and rear racks are made from tubular CroMoly steel with stainless hardware. This means you can probably find someone out there that can torch it back into one piece in the rare instance things go south. The Front Rack is height adjustable and provides either a low or high pannier mounting position, which can be handy depending on terrain. When the ground gets rough, keep your gear high and dry. When the path is smooth and easy, you can load things low and keep everything balanced and stable, with the platform above the wheel providing yet more space for more stuff. It's worth mentioning they've redesigned the Front Rack hardware to be simpler to attach and more compatible with things like disc calipers and fenders. Surly also made attachment plates specifically for their Uni-Crown forks for yet more fork compatibility. This simpler design has fewer moving parts and costs less to manufacture; ergo, costs less for you to purchase. Surly's front rack WILL work with disc brakes on the Troll, Ogre, and Disc Trucker frames. It may take a bit of work to get clearance around the front caliper since the many different calipers out there are many different shapes. The new attachment plates will limit any DIY ingenuity you might need, but if you need to throw a washer or three behind the lower left bolt where the plate attaches to the fork dropout, that's not a big deal. As part of Surly's ongoing effort to make this planet last a little longer, they recently started shipping their racks with a small, reusable Surly Tool Bag that houses the rack struts and hardware. This switch helps eliminate the use of some polybags, thereby minimizing excess waste. Plus, you get a free tool bag out of the deal. Surly Front Rack will haul up to 32kg (70 lb) of well-secured, well-balanced gear over roadways and maintained off-road trails. Front Rack specifications: - Tubing diameter: 10mm - Platform dimensions: 230 x 170mm - Weight: 1382g
Surly Rack (Rear)
$155.00
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.
Surly Ogre
$1,450.00 - $1,499.99
A steel utility vehicle designed for fully-loaded exploration, whether across town or across the country. A Versatile All-Season Commuter Bike If you’re like us, your bike needs likely change by the day, week, month or year. Quite the adaptable little beast, Ogre can get you to your job during the week, then way out of town on the weekend. It’s not sluggish on pavement or gravel and can also hold its own on singletrack. Ogre is designed to be the ultimate steel utility vehicle. It relishes in those “take-the-long-way-home-and-find-some-beverages-along-the-way” sort of commutes. Snow, sleet or sweltering humidity, this is an ideal year-round commuter bike. You can also haul enough crap on it that you don’t even have to go home if you don’t want to. - All the barnacles you could ever possibly ask for including rack and fender, multiple three-pack mounts and mid-blade. - Gnot-Boost rear spacing with Rohloff torque arm slot and Bill/Ted trailer mount - Clearance for 29 x 2.5 or 27.5 x 2.8 tires with fenders
Surly ECR 27.5+
$1,499.99 - $1,900.00 $1,899.99 - $1,900.00 Up to 21% Off
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's 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 27.5+ sizes also feature two sets 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 Straggler 650b
$1,549.99
See that fire road? How about that gravel grinder you've always thought about doing? Surly's Straggler is just the steed you need to explore all the backroads and sideroads. Manufactured from Surly's favored chromoly tubing, paired with a lugged chromoly fork, the frame is responsive, nimble, and showcases steel's inherent ability to damp road buzz. 650b wheels are a great 'tweener size, with speed, traction, and road smoothing comfort. It also has clearance for 42mm tires, a full set of rack and fender eyelets, and custom rear dropouts that let you ride the bike singlespeed or geared. The wide-range SRAM Apex drivetrain will get you through all the ups and downs of any ride, and snappy SRAM Apex DoubleTap shifters make it easy to get through the gears. And control is easy with Hayes CX-Expert disc brakes providing tons of all-weather, all-terrain stopping power.
Surly Karate Monkey
$1,550.00
Karate Monkey is a highly-versatile trail bike that plays the part of 29er and 27.5+ equally well. Multipurpose Hardtail Mountain Bike 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 maniacal 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
Surly Krampus
$1,550.00
Krampus is a dedicated 29+ trail bike that can go over, off of, or through just about anything in its path. 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. "Lean back, hang on, and ride that wild horse." -Thor - 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
