Mountain Frames

The Big Fat Dummy is a long tail cargo bike that took a few too many doses of growth hormones. At first glance, you might say that Surly just put bigger tires on a Big Dummy. But if you said that, you'd actually be very wrong so just… don't. Think of Big Fat Dummy as more of a second or third cousin to Big Dummy rather than a brother. They share some of the same DNA and look sort of similar, but they're two very different bikes and really only interact when they both reach for the potato salad spoon at that family reunion that no one really wants to be at anyway. Now that that's out of the way, let's get down to the nitty gritty of what makes this hulking beast of a bike tick. Surly's goal with designing a cargo bike around fat tires was to create the most stable, stiff, and traction-laden ride possible while hauling a ton of stuff. Big Fat Dummy has a longer toptube and slacker headtube than its more svelt cousin giving it a nice, predictable, and stable ride. They also used thinner, lighter tubing to construct its cargo area so while it's an overall burlier bike, there's not much difference in weight. Big Fat Dummy accepts either 10mm or 12mm axles in the rear with a spacing of 190/197mm. That big ‘ol spacing equates to one thing: tire clearance for days. Big Fat Dummy maxes out at a massive 26 x 5.25" tire.* While that large of a tire provides the most traction and stability a bike can possibly offer, it's also a lot of rubber to push and might not be for everybody. Luckily, Big Fat Dummy is also a blast to ride with 3" tires too. It uses the same 100mm suspension-corrected fork as the Wednesday, meaning if you want to add a little squishy-squishy to your ride, you can throw a Bluto on and let ‘er rip. If you intend to carry a passenger on your Big Fat Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility. All Big Fat Dummy framesets and bikes ship with a Dummy deck, rails, bags, and the aforementioned Dummy Rail Collars so you can immediately start hauling cargo — human or otherwise. Big Fat Dummy is ready and willing to carry all sorts of crap — literally. It's already in use on an organic farm in Ecuador so it's likely that it's hauled some form of manure by now. *Using a 26 x 5.25" tire will cause some drivetrain limitations. For all the nuts and bolts of compatibility read Surly's blog on the subject.

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 they're 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.

What does ECR mean? Anything you want it to. Go camping, ride the Divide Trail, disappear into the woods, and conquer any road. Surly's ECR is a super capable camping machine/trail bike that's outfitted to explore wherever you point the front wheel. Surly's favored chromoly tubing damps road buzz and provides a nimble, responsive ride. The heart of the ECR is the 29+ wheel capability, with clearance for 29 x 3.0-inch tires. Fat tires mean smooth-rolling traction, stability to spare, and a touch of suspension over the roughest terrain. On top of all that, frame eyelets galore are just waiting for racks, fenders, and whatever else to make this your pedal-powered escape pod.

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's Ice Cream Truck turns up the volume on fat. With unmatched traction and float courtesy of super wide tires (up to 4.8-inches wide!), and the flickable geometry of your favorite trail bike, this fatty feels frisky, limber, and ready for action. The symmetrically spaced 190mm rear end uses Surly's Modular Dropout system for an array of rear axles choices. 197mm thru-axle? 190mm geared? Singlespeed? All equally plausible possibilities with the Ice Cream Truck. A 44mm headtube provides fork options, and the frameset ships with a suspension-corrected, 150mm fork with a 15mm thru-axle. Surly's proprietary 4130 chromoly steel and corrosion-fighting ED coating add a hefty dose of tough to this bike. Now, where do you want to ride your Ice Cream Truck?

The Ice Cream Truck goes where most other bikes can’t. Snow, rocks, mud, sand — you name it, and chances are, someone has ridden it on an Ice Cream Truck. Don’t let that terrain-crawling ability fool you into thinking the Ice Cream Truck is slow and sluggish, though. A long top tube (best paired with a short stem) and short stays make it trail-approved and ready to rip. And with 4.8” tires on 100mm rims, “trail” is relative. Show a snowman who’s boss, ride through a sand castle — all while riding the perfect get-away vehicle. Or you can stick to riding terrain that won’t ruin a child’s day. It all starts with Surly's proprietary ED-coated 4130 CroMoly steel. ED coating provides a solid foundation for paint externally while adding a layer of corrosion protection internally. The Ice Cream Truck’s frame is symmetrically-spaced at 190mm and features Surly's MDS dropout system, so you have the option of running a 197mm thru-axle, 190mm geared or a single speed rear end. Each frameset comes with all three MDS chips so you can choose your own adventure. A 132mm wide PressFit 41 bottom bracket allowed Surly to play with the stays a bit more and move them a little further out, creating a much stiffer rear end. If you feel like swapping out the included suspension-corrected, straight blade fork, you’ll have plenty of options thanks to the Ice Cream Truck’s 44mm headtube. In a world full of uncertainties, there’s one thing you can count on: Ice Cream Truck will really take you places. At least when it comes to riding a bike — it can’t do much to help you fix the rest of your life.

Say hello to Surly's rowdy, trail-shredding Instigator 2.0. The no-nonsense chromoly frame is made for charging hard and going big. It's super tough, yet handles nimbly and accelerates like mad. The heart of the bike is Surly's 26+ platform which has clearance for 50mm-wide rims and 2.75-inch tires, so you get endless traction and the rollover-action of a 27.5-inch wheel, coupled with the snappy, go-fast responsiveness of a 26-incher. The geometry is dialed for a 140mm travel suspension fork and features a long top tube and short rear end for more of the same fun. And this thing is versatile, the frame comes with dropouts for rolling singlespeed, or geared with a quick release or a 142x12mm through-axle with a Shimano direct-mount hanger.

Years ago the Karate Monkey helped start the 29” wheel movement and, as time’s gone by, many companies ­– Surly included – have experimented with even more wheel sizes. With so many different types and sizes of tires now on the market, riders have begun to understand the effect that tire width has on overall wheel diameter, and with ample tire clearance, you can see the benefits of multiple wheel sizes all on one bike. 27+ tires have the same rolling diameter as a 29” wheel, yet you get all the traction and flotation benefits of extra-wide knobbies. And that’s just the tires. The Karate Monkey frame has recently gotten a make over that includes the addition of features like internal dropper post routing, a new tubeset that uses the same trumpet tubes found on our Instigator 2.0, and a slight tweak in geometry that is more progressive and trail-oriented. The Karate Monkey uses a horizontal dropout with a derailleur hanger that features Gnot-Boost spacing, which gives the rider the ability to run any kind of mountain bike hub they choose. 10 x 135mm QR, 12 x 142, or 12 x 148 Boost will all work in the Karate Monkey frame. The frame uses a 44mm headtube for broad fork compatibility and is ED coated for an added layer of internal protection. If, at any point, you decide you want to throw on some skinny meats, standard 29” wheels and tires can be swapped in with no issue. If you want to round-house kick some trail right in the face, the Karate Monkey is your sled.

The Karate Monkey frame features updated, progressive trail geometry, a new tubeset, and Surly’s Gnot-Boost rear dropout system to support multiple drivetrain and wheel size configurations. - 100% Surly 4130 chromoly steel frame and fork; double-butted main triangle and 44mm headtube - Tubeset uses the same trumpet tubes found on Instigator 2.0 frame - Adjustable rear dropouts with 145mm Gnot-Boost spacing works with 142 x 12, 148 x 12mm, and 135mm w/ 10/12 washer - Internal dropper seatpost routing - 30.9mm seat tube ID - Clearance for 29 x 2.55 or 27.5 x 3 tires

Surly's Krampus rolls fast, holds speed, and devours corners. It's designed for 29 x 3-inch tires, offering increased traction, incredible float, huge rollover, and low-fi suspension to take your trail ride to new heights of fun. Surly built this frame and fork out of tapered and butted chromoly and gave the frame a long top tube and short chainstays, so it's playful, smooth, versatile, and durable. Boost front spacing keeps you current with the latest MTB tech, and, "Gnot Boost," rear spacing means you can run any the rear hub you want: 135 x 10 QR, 142 x 12mm, or 148 x 12mm thru axles. This frameset also offers internal dropper post routing so you're granted a license to get rowdy, which you really can't help but do on a Krampus.

The Surly Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. It’s the bike you turn to when you’re not entirely sure what the night has in store. It’s the bike to grab when you want to have just as much fun riding to the trail as you do on the trail, itself. Singlespeeding is an integral part of Surly’s DNA, and the Lowside continues the tradition, by taking a simpler approach to trail riding. - 100% Surly 4130 chromoly frame, main triangle is double-butted; 1 1/8" threadless chromoly fork - Singlespeed "specific" (derailleur hanger: yes; Trip Guides: no) - Dropper post routing - Gnot-Boost rear spacing - Front and rear thru-axles - 26 x 3" or 27.5 x 2.8" tire clearance

If you’re like us, your bike needs will likely change by the day, week, month or year. Ogre will get you to your job during the week, then way out of town on the weekend. It even has the chops to handle a cross-country trek or nine. 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. You can also haul enough crap on it that you don’t even have to go home if you don’t want to. For this year, we simplified Ogre a bit. We removed the canti studs, so it is now a disc brake-only beast. Now, before you start yelling at us about how the canti studs were the only reason you were even considering buying an Ogre and now we’ve left you contemplating your very existence in this ultimately-doomed universe, hear us out. Rim brake 29er rims — like the ones that you would need to have to make use of those canti studs in the first place — are becoming increasingly harder to find. We could have given you a feature that you’d end up not really being able to use in the future but what kind of monsters do you think we are? To quench your unquenchable thirst for rim brakes, check out the Troll. As far as other updates to the frame go, that about sums it up. Ogre still has everything else you’ve come to know and love: two water bottle mounts, four sets of three-pack bosses, mid- and low-blade fork eyelets, threaded holes for racks, fenders, and trailer mounting nuts, and a Rohloff OEM2 axle plate slot. It still features horizontal-slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefy tire clearance. It’s still fully compatible with both 29 x 2.5” and 27.5+ tires. In the complete bike version, we’ve opted to go with a 1x drivetrain and a flat handlebar. We typically try to avoid BS cliché terms like “Do-It-All” or “Swiss Army Knife of Bikes”, so we’ll just say that Ogre can probably handle most of the ideas that are bouncing around in your head.

If you’re like us, your bike needs will likely change by the day, week, month, or year. Surly's Ogre can get you to your job during the week, then way out of town on the weekend. The latest version of the Ogre has received some fantastic updates, including horizontal slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefier tire clearance — all in a 29er/27.5+ platform. Ride it any day of the week; it’s not sluggish on pavement or gravel and can also hold its own on singletrack. - Gnot-Boost spacing allows the use of 135mm QR hub, 142 x 12mm thru-axle, or 148 x 12mm Boost hubs. - Full-length Surly Trip Guide housing line guides for derailleurs and brakes - Two sets of bottle cage mounts - Disc and rim brake compatible with removable post cantilever pivots - Upper seatstay threaded barrels with mid- and low-blade fully threaded through-blade fork eyelets - Threaded holes for racks, fenders, and trailer mounting nuts - Rohloff OEM2 axle plate mounting slot - Tire clearance for 29 x 2.5” or 27.5 x 3”

The Surly Pack Rat is designed around porteur-style racks and front-loading optimization, with a front cargo-specific design to eliminate steering issues. The fork features internal routing for generator hubs and rear frame dropouts to accommodate multiple drivetrain configurations. It’s an ideal choice for loaded commutes and bike trips with a lighter load, but also rides great when unloaded. - 100% Surly 4130 Chromoly frame, main triangle is double-butted; 1-1/8" threadless brazed Chromoly fork - Bosses front and rear for cantilever or linear-pull brakes, rack and fender eyelets at the dropouts, eyelets at the crown, and fully threaded through-blade fork eyelets for a front rack - Semi-horizontal dropouts with a derailleur hanger for geared or singlespeed drivetrains and/or wheelbase adjustability

The Surly Pugsley may be the original fat bike, but this one is far from the original. Previously a great all-around fat bike, the Pugsley has been redesigned to be an ideal off-road touring and exploration rig. Surly lengthened the chainstays 12mm for stability when loaded and so your heels float effortlessly past panniers. The tweaked rear rack mounts on the dropouts let you center your rack over the wheel, despite the offset rear triangle. Those dropouts will take a 142 x 12mm thru axle if that's your schtick, but can also be used with 135 x 10mmm QR hubs with Surly's Adapter Washers. Pugsley brings back the 135mm-spaced offset fork, so you can run a front wheel with a spare cog or freewheel as a bail-out option to swap with the rear if your internally-geared hub freezes up in neutral or you smash your derailleur having too much fun. A plethora of three-pack mounts give you gear-hauling options aplenty, so go wild with your build. - 100% Surly 4130 chromoly frame, main triangle is double-butted; 1-1/8" threadless brazed chromoly fork - Four sets of Three-Pack Mounts (two on the fork, two on the downtube), a water bottle mount on the seat tube, and front and rear rack mounts - 142 x 12mm rear dropout (or 135 x 10mm QR with Surly 10/12 Adapter Washers) with Rohloff torque arm slot - 135mm-spaced fork with 17.5mm offset for wheel swappability - 26 x 4.8" tire clearance in frame (with drivetrain restrictions), 26 x 4.3" tire clearance in fork

Off-road touring can be a zesty enterprise, but it’s not without its perils. Bicycles are simple machines that are extremely efficient, but all simple machines carry along with them the chance of breaking down. This efficiency can get you in trouble if your bike decides to break down far away from the comforts of your parent’s basement. If you’re going to ride your bicycles where no one can see, you better take gear that’s up to the task. Troll is up to the task. Surly's Troll was once a simple mountain bike frame with a few extras that made it nice for touring. The Troll has evolved into a frame that has been pushed deeper into the category of off-road touring. Its geometry is no longer suspension corrected, which gives it more room for a larger frame bag. The chainstay yoke has been redesigned to be fully compatible with 26+ tires and comes with the always-comfy Jones Loop bar. The dropouts still allow you to run disc brakes, fenders, a Rohloff hub, and racks simultaneously. It also comes with more braze-ons than you thought possible – there are four triple bottle mounts on the fork alone (don’t get excited, you can only run one Anything Cage per fork leg), as well as two more triple bottle mounts on the down tube. Troll is a bike that has one purpose – and that purpose is to carry you as far away from society as possible.

The Wednesday is the result of over a decade of Omniterra design experience distilled into one steel package. It can easily ride over or through most anything our other Omniterra bikes can and then some. With the Wednesday Frameset, Surly borrowed elements from some of their Trail and Touring models to create an Omniterra whip that can truly handle anything you want to attempt. Want to point it down the side of mountain? Go ahead, roll those dice. And if you make it to the bottom, you’ll be able to ride back to the top for round two. Wednesday’s geometry is spry enough to get you through techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish on terrain-crawling stuff. While Wednesday is plenty confident on terrifying terrain, it also has the chops for any sort of expedition you may want to undertake. Surly gave it all the necessary braze-ons and mounts for whatever accoutrements you feel necessary in your travels. Racks? Front and rear, friend. Fenders? You got it. Bottle mounts? How does triple bottle bosses on both fork legs and the down tube, and two sets of standard mounts on the main triangle grab you? They even gave Wednesday internal routing for a dropper post and Surly Trip Guides to keep everything nice and neat and free of rat’s nests. In the dropout department, Wednesday uses a cast steel, rear-facing, slotted dropout that can exit either rearward or vertically. They’re compatible with either 10mm or 12mm axles and are spaced at 170/177mm.

The Wednesday is Surly's all-terrain fat bike frame. The frame features trail-ready geometry, 4.6-inches of tire clearance, provides lots of cargo carrying capabilities and is suspension corrected for use with a 100mm suspension fork (sold separately). - 100% Surly 4130 CroMoly steel with 44mm headtube and internal dropper post cable routing - Frame is ED Coated for increased life expectancy - 1-1/8" straight steerer fork, 4130 CroMoly - 100mm threaded bottom bracket shell - Universal cast dropouts accommodate thru-axle or quick-release standards

Wednesday is a frame with a decade of Surly's Omniterra design experience distilled into one steel package. Wednesday can ride over the same type of pretty much anything all of their other Omniterra bikes can, but they borrowed elements from both their Trail and Touring categories to create an Omniterra ride that can truly handle anything you want to attempt. Want to point the thing down a mountain and roll those dice? Wednesday has geometry spry enough to get you through the techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish when you have to ride back to the top. It also has the chops for any sort of expedition you may want to undertake. It has plenty of bottle mounts; triple bottle bosses on both fork legs and the down tube; standard bottle mounts on the seat tube and underside of the down tube; plus rack mounts on the frame and fork and fender eyelets on the dropouts, along with barrel bosses on the crown, fork legs and mid-blade, thru-blade eyelets on the fork as well. It also has internal dropper post routing and Surly Trip Guides to manage all the housing and cables on your frame with style. Wednesday also has its very own dropout design as well – a rear-facing, slotted dropout that can use either 10mm or 12mm axles and exit rearward or vertically. They’re cast steel and spaced at 170/177mm. Wednesday gives you a lot of options in the tire clearance category. In the full-forward, short chainstay position you can run 26 x 3.8? tires on 80mm rims and in the full-rearward, longer chainstay position you get the option of 26 x 4.6? tires on an 80mm rim. Wednesday is made out of Surly's own proprietary 4130 CroMoly steel and is ED coated for extra protection from the elements.

Let's not kid ourselves—downhill is all about speed. And when it comes to squeezing every last ounce of fast out of a track, your machine needs to be just as fine-tuned as your skills. That's why we offer our legendary, World-Cup-proven S-Works Demo 8 as a frameset. It's constructed from our finest carbon fiber, FACT 11m, for unparalleled stiffness and strength. Meanwhile, it's been built aboard our ultra-capable S3 27.5 Geometry to ensure a roomy top tube for added control, ultra-short, nimble chainstays, a low bottom bracket that keeps you feeling planted, and a slack front end that provides the utmost in responsive handling at speed. For suspension, this Demo features 200mm of travel delivered via a game-changing custom Ohlins TTX rear shock with both high- and low-speed compression adjust. Altogether, it's a blank canvas of pure performance and potential speed. Build it how you want it, and race it like you mean it. - The frame features a full FACT 11m carbon fiber construction for low weight and heightened levels of strength and stiffness, which is amplified by its asymmetrical frame design that still leaves plenty of access. This has also been paired with our proven S3 Geometry that increases maneuverability and responsiveness, while the 200mm of travel at the rear makes the bike capable of taking on the biggest of hits in stride. - Custom Ohlins rear shock delivers unparalleled DH performance. It offers high/low speed compression adjust that stands independent of the rebound adjust, enabling you to fine-tune the shock for the track at hand. It's 200mm of coil-sprung travel that stands without rival, and you won't find anywhere else. - Thomson alloy seatpost features one of the most durable constructions out there, without coming at the expense of a high overall weight.

The perfect start to your dream build, the S-Works Enduro 27.5 frame is ready to be built exactly how you want it. No matter how you build it, though, you're sure to experience a fast, flick'able, and stupid-fun mountain shredder. We gave it a geometry that features a slacker front end, a longer top tube, short chainstays, and a lower bottom bracket. All of this together makes the bike truly feel glued to the ground, and the platform is more responsive and capable then ever. We even added some bits, like integrated storage with a SWAT Door at the down tube, and made "old" new again by making a triumphant return to a threaded bottom bracket. To keep the weight down, the frame is constructed from our top-tier FACT IS-X 11m carbon fiber. And to ensure top-level performance on the descents, this material choice is greeted by 170mm of plush rear and 170mm front travel, plus a geometry that can be "adjusted" via a shock extension with a "low/high" setting. - The frame's FACT IS-X 11m carbon fiber construction stands as the pinnacle of lightweight, efficient, and tough trail performance. It's been built off our 27.5 Geometry in order to provide an aggressive, well-rounded ride. And with internal Command Post IR routing, a return to a threaded bottom bracket, and an integrated SWAT Door at the down tube, you get a bike that's clean, dependable, and ready for anything that the trail has to offer. - The custom Ohlins STX single tube air shock at the rear features high- and low-speed compression, as well as low-speed rebound. You'll also find an extra-volume reservoir that allows for more oil, which results in more control and an ultra-plush ride quality.

You like gettin’ rowdy, we like gettin’ rowdy, so we figured, “Why not create a bike that lets us do the thing we all love most?” Well, that’s exactly what we did with the Enduro. Its playful and nimble 27.5-inch wheels and modern frame have been purpose-built to make short work of the rockiest, gnarliest, and steepest trails, while still being able to climb well enough to get you there. Witness the sickness. Our quest was to create the perfect long-travel trail bike, and it all began with a close look at the geometry. Basically, we modernized it— slacking out the front end, lengthening the top tube, shortening the chainstays, and lowering the bottom bracket. All of this together makes the bike truly feel glued to the ground, and the platform is more responsive and capable than ever. We then added some crucial bits to make your ride, well, better. We're talking stuff like integrated storage with a SWAT Door at the down tube, a triumphant return to a threaded bottom bracket, and internal cable routing with guides that make cabling super easy. And to keep the weight down, this S-Works frame is constructed from our top-tier FACT IS-X 11m carbon fiber. To guarantee high degrees of "shredability," this material is greeted by 170mm of plush front and rear travel, plus a geometry that can be "adjusted" via a shock extension with a "low/high" setting. To get you started on your way to complete dream build status, this frame includes a FOX Factory X2 Air (216x57mm) rear shock with 170mm of travel. - The frame's FACT IS-X 11m carbon fiber construction stands as the pinnacle of lightweight, efficient, and tough trail performance.

With more World Championship titles, Olympic medals, and Cape Epic wins than you can count, the S-Works Epic LTD frame can truly be built as the fastest XC bike on the planet. Fast and flat, rowdy and technical, punchy and hard—no matter the course, it’s the best tool to get you to the top of the podium. Race courses have evolved over the past few years. They're more technical, steeper, and more challenging to ride. But instead of quivering in our boots, we saw this as an opportunity to make something special—something that both World Cup athletes and XC riders alike can instantly feel the benefit from. We looked at the sum of parts that make a bike handle well, like the head angle, reach, stack, chainstay length, fork offset, etc., and reevaluated all of it. Increasing the reach made a bike that was more stable at speed and generally more comfortable to ride. Dropper posts? Yep, those fit, and not just a short-travel XC option, but full-length droppers that fit in the 30.9mm seat tube. Head angle? We slacked that out, but not without evaluating the overall handling package. It now lands on a custom offset, 42mm fork that works with the slacker head angle in order to behave itself in tight corners and through switchbacks. Next comes Brain 2.0. The original Brain changed the way the bike world looked at suspension, both in its inefficiencies and benefits alike. And oh, was it good. It won races and put a flag in the ground for us as a true leader in innovation and suspension development, but we knew that we could make it better. Simple physics told us that, by moving the Brain closer to the rear axle, it would be in the most sensitive spot. And after countless hours with the RockShox team, the Brain became more than just a slight upgrade. It's totally reborn. Now, it reacts seamlessly to bump forces, it has much more consistent damping performance, and finally, it integrates the hoses into the suspension links. This, in turn, improves oil paths, and it creates an incredibly sleek package that outperforms anything on the market. The Epic also has a rider Rider-First Engineered design that places complex carbon pieces in all the right places, and this greatly increases stiffness in the front-end for a vast improvement in ride quality and control. To go along with this, each frame size has size-specific tubes that result in the stiffest, best riding XC bike we've ever developed—no matter the frame size. And while stiffness, Brain technology, and geometry features are cool and all, we know what you're thinking, 'What about weight?' We're glad you asked. With the goal of the new Epic to be the fastest XC mountain bike we've ever made, weight was at the top of our priorities list. We started with an efficient frame layout and tube shapes that feature clean cable routing, integrated channels through the shock extension, straight tubes with less curves, and optimized torsion profiles in every section. And, if you're curious, this weight savings is equivalent to shedding a chainstay and shock extension from the previous Epic—nearly 350 grams. This frame comes equipped with a custom RockShox Micro Brain rear shock w/ a Spike Valve. Building out the rest of that dream build is up to you—we hope to see it out on the course soon. S-Works FACT 12m carbon fiber frame is the best combination of stiffness, strength, and light overall weight, resulting in the utmost efficiency and speed. Meanwhile, the new geometry, RockShox Brain shock, and 100mm of travel, make the Epic the best handling, fastest XC bike you've ever been on.

The S-Works Epic is the fastest XC rig on the planet—a bike with more World Champ titles, Olympic medals, and Cape Epic wins than you can count. And now, we’re offering the S-Works Epic in a limited-edition, Troy Lee Designs frame and fork combination. Head to toe, this rig looks fast. Of course, countless race wins around the world testify to how damn fast the S-Works Epic truly is, but you know, it never hurts to look the part. At the heart of it all is the S-Works FACT 12m carbon fiber frame—a chassis that offers the best combination of stiffness, strength, and light overall weight available. This bike, however, isn’t merely fast, it’s also one of the most capable cross-country machines on the World Cup circuit, with a geometry that’s designed to let you tackle the most technical courses at speed, with complete control. Speaking of speed and control, the TLD-edition frame sports 100mm of insanely efficient front and rear suspension. That efficiency comes courtesy of the ultralight RockShox SID World Cup fork and Brain 2.0 rear shock. The unique inertia valve in both the front and rear suspension help the bike stay firm and fast when the trail is smooth and then automatically become plush (and even faster) when the trail suddenly fills with rocks and roots. Brain-equipped suspension is, quite simply, suspension made smart. And since this is the TLD-edition we’re talking about, we also gave that RockShox SID World Cup fork and Micro Brain rear shock matching Troy Lee graphics. - S-Works FACT 12m carbon fiber frame is the best combination of stiffness, strength, and light overall weight, resulting in the utmost efficiency and speed.

There's not much that matches the feeling of powering up a pitch on a featherweight bike, and we designed the new S-Works Epic Hardtail frame with this in mind. It's less than 900 grams, exceptionally stiff, and it features a Rider First Engineered design. It's the perfect jumping off point to begin creating your dream build. Over the last decade, cross country racing has evolved into a completely different animal—the courses are rowdier, more technical, and overall, they're inherently different. Because of this, we realized that the best bike for the job needs to not only be lightweight and stiff but also be able to descend and climb with equal prowess. Determining the best geometry was the easier of the two, as we took our current XC race geo and added some trail DNA to the mix. This equates to a longer top tube, a shortened head tube, and a slacked-out front end, the result of which is a tremendous increase in downhill stability, plus a wider fit range. And just as importantly, this doesn't require any sacrifice of climbing proficiency. The weight aspect was more complicated, though. We were posed with the question, "How do you take weight out of something that's already so light?" But the answer was relatively obvious: you get the best mountain bike engineers together in one room and let the magic come out. Up until now, there were two ways to lighten up a frame—use less of the same grade of carbon or use less of a higher-grade carbon. Option one is never a viable solution as it sacrifices stiffness and strength, two attributes that shouldn't be tampered with. And while we did end up using option two, we weren't content with the amount of weight we could cut out by just using a different grade of carbon. So how else do you cut weight? Well, we began looking at our layup schedules to see if they could be improved, which shed light on a new discovery—layup inefficiencies. Beginning with our Rider-First Engineered frame technology, each size Epic Hardtail is specifically tailored to size—every carbon layup and tube are exclusively selected based upon hundreds of hours of collected ride data. What does this mean for you? It not only creates the optimal balance of rigidity, weight, and responsiveness across every frame size, but it led us to the discovery of how to save weight through the studying of the layup. Through extensive layup studies, we made the discovery that, by further controlling the construction and layup schedules, we could drastically decrease weight, all while maintaining the ride characteristics that you'd expect from a top-level XC race bike. With this discovery, each frame now features complex cut carbon plys that allow difficult junctions to be covered with less overlap. And while this does complicate the carbon frame puzzle by adding more pieces to the mix, it allows us to design and place them more intelligently. The result of this is a lighter frame, stronger junctions, and a drastic increase in stiffness. We then took the weight savings one step further by using Japanese military ballistic-grade carbon, which we now call 12m, to create the lightest mountain bike we've ever made. How much lighter of a frame, you ask? Less than 900 grams for a size Large frame—the same weight as a full 24oz Purist water bottle. - To provide the optimal blend of stiffness, crazy light weight, and strength, we constructed the frame from our S-Works FACT 12m carbon fiber. And when combined with our XC 29 Geometry, this Epic is guaranteed to deliver uncompromising, blistering speed and agile handling come race day—no matter the course.

We’ve heard it all before: “This bike’s for going fast, that one’s for having fun.” “This one pedals well, that one shreds.” Why not make one bike that does everything well? Well, we did, and it's called the S-Works Stumpjumper. Unrivaled handling and stiffness, sublime suspension kinematics, and a complete abandon of proprietary nonsense—it rides like a dream. And with 27.5-inch wheels, this model blends responsiveness with stability to create the pinnacle of trail performance. - The Stumpjumper's asymmetrical, FACT 11m carbon fiber construction is lightweight, stiff, and ready to take on the trail. It's built off our 27.5 Trail Geometry, so it's just the right amount of both capable and comfortable. And with SWAT integration in the downtube, a threaded BB, easy cable routing, and an all-new chain silencer, it's ready for anything the trail, or you, throw at it. - FOX FLOAT DPX2 Factory has three modes—Open, Trail, and Firm—that control large compression adjustments on-the-fly. There’s also a tool adjust compression adjustment that allows for fine-tuning of the compression in Open mode.
