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

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 All-Around Fat Bike Wednesday sits in the middle of our Trail category, but don't let that fool you into thinking that's its only use. 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.

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.

Don't worry, we get it...your training buddies all think you're a bit "particular". You may or may not have stockpiled your favorite grips just in case they ever get replaced by a new model. Perhaps your trailside toolbox would make a quality control engineer blush. Whatever the case, you won't find any judgment here. Instead, the endlessly engineered S-Works Epic Frameset is here for you to let your discerning tastes run wild. We sweated every last detail when designing the S-Works frame, from an endlessly refined layup schedule that re-examined every last ply of FACT 12m carbon to optimize weight savings and ride dynamics, to the weight-shedding carbon shock link, all so that you focus on the rest, knowing that you're starting with the most capable canvas in the world. True to form, the latest Epic continues the tradition, taking advantage of the most efficient Brain suspension we've ever created to ensure it's always on a first-name-basis with fast. Re-engineered hand-in-hand with the new Epic, the latest BRAIN design resets the expectation for efficiency, employing a new race-tuned pedaling platform to ensure every watt possible is translated into forward motion, while handily soaking up momentum-killing chatter and big hits alike, all more smoothly than ever. Perfectly matched to the frame's BRAIN system, the S-Works Epic frameset's Position-Sensitive BRAIN fork benefits from RockShox's latest SID Ulitmate SL chassis for next-level steering stiffness that still manages to keep the gram count to a minimum. - If speed could talk, it'd introduce itself as the all-new S-Works Epic frame. Offering 100-millimeters of brilliantly efficient Brain-controlled travel, the S-Work Epic increases rear-triangle stiffness for peerless power transfer, while the use of FACT 12m carbon, a dedicated layup, and a full carbon shock link also make it the lightest full-suspension frame we've ever created, all while offering the most capable handling in an Epic yet. Nice to meet you, speed. - Pairing 100 millimeters of the most efficient travel on earth with RockShox's svelte-yet-stiff SID SL Ultimate chassis, the RockShox SID SL Ultimate BRAIN fork serves as the pinnacle of XC-race suspension perfection.

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.

Going all the way back to when inspiration for the EVO lineup was still waiting to be drawn from employee bike racks packed with hot-rodded Epics sporting shorter stems, wider bars, and longer forks, Epic EVO has always been about taking the Epic's unmatched pedaling efficiency, nimble handling, and featherweight chassis and injecting an added dose of capability to make quick work of technical singletrack and demanding descents. While the Epic EVO sees a seemingly modest 20-millimeter increase in suspension travel up front over its Epic stablemate and just 10-millimeters out back, we've worked overtime to make sure it's been implemented in a way that'll have you saying "Whoa!" as soon as you hit your first stretch of singletrack. Meticulously engineered to retain as much of the Epic's standard-setting efficiency as possible, the EVO's new suspension kinematics work in concert with Rx XC Tune customized suspension front and rear to ensure you're able to make the absolute most out of every inch of travel on tap, while still offering increased anti-squat characteristics for improved pedaling efficiency. With plenty of practice at staying ahead of the curve, the Epic EVO now lays claim to the most capable iteration of our Progressive XC Geometry ever to grace an Epic. It's also more versatile than ever thanks to a new flip chip-equipped rear end that allows riders to adjust headtube angle and bottom bracket height to easily customize Epic EVO's handling characteristics. - Flip It To Rip It: Tune the ride of the Epic EVO's FACT 12m carbon frame to match your preferred handling characteristics with flip-chip simplicity that allows riders to steepen the EVO's headtube angle by half a degree while raising the bottom bracket height by six millimeters.

This is the bike that defines the very genre that bears its name, the S-Works Enduro climbs with utmost efficiency yet stays calm on even the gnarliest descents. It features a bomber, yet lightweight carbon frame that blissfully tackles the kind of terrain that chews up and spits out lesser bikes. ASTONISHINGLY FAST, UP AND DOWN THE TRAIL Stomp on the pedals and the new Enduro accelerates far quicker than you'd expect possible from a downhill bruiser. To start, we increased anti-squat, so the suspension better-resists pedal bob. Then, to further its efficiency, we re-directed the angle of the chainstay and upper shock linkages for a much more efficient design. The end result? Less bobbing, more speed. FAST STARTS WITH FIT Fast and fit aren't mutually exclusive, which is why the progressive geometry of the Enduro has been designed for going up and down. To start, seat tubes and stack heights don't grow massively between sizes, meaning you can now pick a frame size based on both your height and your riding style. Pair this new sizing style with a slacker head angle, longer reach, and steeper seat tube across the line, and you're left with a quicker and more capable steed, no matter the size. INCREDIBLY CAPABLE If the Enduro looks like its sibling, the Demo, it's because they share plenty of downhill DNA. A more-rearward axle path reduces wheel hang-up on big impacts. A low- and forward-positioned shock keeps it planted and confident-feeling at high speeds. And balanced chassis stiffness helps the front-end steer precisely and keeps the rear-end tracking like it's on rails. Add it all up and you have a bike that laughs in the face of the steepest, rockiest trails.

When we say "The Ultimate Trail Bike," we mean it—the all-new Stumpjumper is everything you could ever ask for in a dirt-shredding steed. Want a bike that climbs with ease? The Stumpjumper delivers, with the help of a ground-up suspension re-design and a lightest-in-class frame weight. How about something that's ready to shred when the trail turns against you? That suspension re-design, paired with new Trail Geometry and a Rider-First Engineered frame that's the perfect blend of stiffness and lightweight, turns the Stumpjumper into an absolute monster descending. Point the front wheel where you want to go and be ready to party. THE TRAIL BENCHMARK When we set out to design the all-new Stumpjumper, we pursued some hefty goals. We went after the lightest-possible weight that sacrifices nothing in terms of durability, a stiff chassis that corners on rails, and a geometry that everyone can enjoy, all with the best suspension kinematics we know how to design. Turns out, you can have your cake and eat it too with the new Stumpjumper. THE SWEETEST 130MM OF TRAVEL YOU'LL EVER RIDE We massaged the kinematics of the Stumpjumper suspension to bring out the very best all-round performance possible in a 130mm package. Countless hours of suspension lab development and field testing created a refined mid-travel ripper that eats big terrain like a gravity fed beast, handles like a dream everywhere, and climbs like it has a motor. PROGRESSIVE GEOMETRY The S-Sizing geometry of the new Stumpjumper hits the progressive sweet spot. It's long, low and slack, with a short offset fork and a steeper seat tube angle. These numbers combine to make your ride more stable, more carvealicious, more comfortable climbing, more better everywhere. With FlipChip adjustability you're able to further fine-tune your fit, ensuring that your new Stumpjumper performs flawlessly on whatever terrain you choose. RIDER-FIRST ENGINEERED Rider-First Engineered frames use a size-specific approach to ride characteristics that ensures every frame performs flawlessly. So, whether you're a Grom riding an S1, or in need of the lengthy S6, you'll experience the same ride characteristics—on-rail cornering and balanced front and rear stiffness, all at the lightest-possible weight: 2,250 grams (S-Works, Medium, with rear shock). SWAT When we introduced the SWAT door on the Stumpjumper in 2016, we increased pocket space, and added room for those “oh s**t” pumps and flat accessories. With the new Stumpjumper, we've kept those same design hallmarks that you know and love.

Going all the way back to when inspiration for the EVO lineup was still waiting to be drawn from employee bike racks packed with hot-rodded Epics sporting shorter stems, wider bars and longer forks, Epic EVO has always been about taking the Epic's unmatched pedaling efficiency, nimble handling and featherweight chassis and injecting an added dose of capability to make quick work of technical singletrack and demanding descents. While the Epic EVO gains a seemingly modest 20 millimeters of front and 10 millimeters of rear travel over its Epic stablemate, we've worked overtime to make sure it's been implemented in a way that'll have you saying 'Whoah!' as soon as you hit your first stretch of singletrack. Meticulously engineered to retain as much of the Epic's standard-setting efficiency as possible, the EVO's new suspension kinematics work in concert with Rx XC Tune customized suspension front and rear to ensure you're able to make the absolute most out of every inch of travel on tap, while still offering increased anti-squat characteristics for improved pedaling efficiency.

Featuring an all-new design, with an adjustable head tube angle, 150mm of performance tuned travel, and the adaptability of S-Sizing, this thing is an absolute ripper. The S-Works Stumpjumper EVO—get rowdy. This S-Works Stumpjumper EVO Frame is the perfect canvas to imagine your ultimate ride. Build your totally custom dream bike, make it a reality, and shred happily, partner, no matter where those trails are, or how rowdy they get. 150MM OF TRAIL-TAMING TRAVEL - All the travel in the world is useless without the proper kinematics, which is why we kept it at the forefront of the new Stumpjumper EVO design. With the learnings from the suspension design on the Demo and Enduro, and practically countless hours of field and suspension lab development, we've not only improved the pedaling performance of the Stumpjumper, but we've made it more capable, agile, and lively. We increased anti-squat, so the suspension better-resists pedal bob and then, we further-improved bump performance on square-edge hits. Bottom line? This thing shreds trails not legs. ADJUSTABLE GEOMETRY - The S-Sizing geometry of the new Stumpjumper EVO is our most progressive yet. Long, low, slack, a short offset fork, a steeper seat tube angle—they're all the talk of the town because they make your ride better. But the perfect geometry is different for different riders, which is why the geo on the new Stumpjumper EVO is fully adjustable with six different settings. Not only are you able to adjust the BB height by 10mm, but you can adjust your head tube by two-degrees. RIDER-FIRST ENGINEERED - Rider-First Engineered frames use a size-specific approach to ride characteristics that ensures every frame performs flawlessly. So, whether you're a Grom riding an S1, or in need of the lengthy S6, you'll experience the same ride characteristics—on-rail cornering and balanced front and rear stiffness, all at the lightest-possible weight. SWAT - When we introduced the SWAT door on the Stumpjumper in 2016, we increased pocket space, and added room for those "oh s**t" pumps and flat accessories. With the new Stumpjumper, we've kept those same design hallmarks, but have increased the volume and added a SWAT Bladder, that gives you an extra 22oz of water hidden in your downtube. Yes, it's the same size as a small bottle.

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 fast-rolling 29-inch wheels and modern frame have been purpose-built to make short work of the rockiest, gnarliest, and steepest trails, while still climbing 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 makes 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 160mm 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 160mm of travel. - 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 29 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 FOX Factory X2 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.

The S-Works Epic Hardtail is the lightest and most capable carbon hardtail frame ever created. Need we say more? While that does a great job of summing things up, if we're being honest, we're still a bit too proud to leave it at that. An impressive 140 grams lighter than the already ‘how'd they do that'-light Epic Hardtail frame, the S-Works frame makes use of our FACT 12m carbon to cut a figure that'll make any gram-counter swoon, while still offering riders enough capability and composure to wring out extra seconds on any section of course, not just the groomed bits. Working towards the lightest bike possible has long been the race within the race, but at what cost? The battle of the grams certainly hasn't been without its casualties, with hardtail XC race bikes coming to stand for a harsh, twitchy ride at the expense of capability and versatility. But who said fatigue from fighting against your own bike makes you any faster? Instead, recognizing that the fastest bike is more than simply the lightest bike, we said out with the jarred-to-death tail, the measure-your-posterior's-sorrows-by-the-yard tail and in with the avant-garde tail. The ridiculously capable, mystifyingly comfortable, head-shakingly light and all-around fast, Epic Hardtail. Sure, we optimized every inch of the Epic Hardtail frame to achieve the lightest production hardtail frame in the world anyway, but we also prioritized our commitment to creating an Epic Hardtail that's as capable as it is comfortable with aggressive singletrack-inspired geometry, increased tire clearance and a frame obsessively engineered for increased vertical compliance, all while creating a bike that lives and breathes the fundamentals of fast. - Ridiculously capable and refreshingly compliant with a weight that'll make most road frames jealous, the FACT 12m carbon S-Works Epic Hardtail frame isn't just light, it's the lightest production hardtail frame ever produced.

Spearfish was designed under a simple premise: that efficiency and precision result in speed. Whether pursuing an ultra-endurance record or working to keep the hard chargers off your back on local training laps, Spearfish’s efficient Split Pivot suspension design rewards the rider. The lightweight carbon frame and 100mm Fox Float DPS Performance Elite shock provide a platform for the ultimate progressive XC bike. Eliminate excuses with Spearfish.

The new Ascent is more adaptable than ever. The frame is tig-welded with heat-treated, triple-butted Ritchey Logic steel tubing that features rack and fender mounts and a third bottle mount under the downtube, while a new Ritchey steel fork offers up multi-purpose, rack, fender and dynamo light mounts. Other notable features of the new Ritchey Ascent include post-mount brake compatibility, 148mm spacing and an external seat collar. Throw a mountain bike bar on it and some 27.5" wheels for more trail-oriented adventures. Or ride it with drop bars and 29" wheels for some longer distance rough road riding. However you choose to roll, your riding possibilities are limitless atop the new Ritchey Ascent. - Includes rack and fender mounts and ability to run a mounted dynamo light - Features the new Ritchey steel fork with an 1-1/8" straight steerer - Frame: heat-treated, triple-butted Ritchey Logic steel tubing - TIG welded - 148mm spacing (12mm alloy thru-axle included) - Wheel and tire compatibility: 27.5" x 2.6" or 29" x 2.6" - Can accommodate 1X or 2X chainrings

If there's one thing Tom knows, it's dirt. When he first designed the Ultra, he knew it would appeal to riders who demand specific ride characteristics and dirt slaying only he could deliver—and that was in the 1980s! Good design withstands the test of time, and the latest iteration of the Ultra is a prime example. Like its predecessor from 30 years prior, the new Ultra occupies a unique ride space from cross-country riders looking to get rowdy and go big to enduro riders lusting for some all-mountain shredding.

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

When we say "The Ultimate Trail Bike," we mean it'the all-new Stumpjumper is everything you could ever ask for in a trail-ripping steed. Want a bike that climbs with ease? The Stumpjumper delivers, thanks to a ground-up suspension redesign and lightest-in-class frame weight. How about something that's ready to shred when the trail turns downhill? That suspension re-design - paired with new Trail Geometry and the Rider-First Engineered frame's perfect blend of stiffness and light weight - turns the Stumpjumper into an absolute monster descending. Point it where you want to go and let the party begin. - THE TRAIL BENCHMARK - When we set out to design the all-new Stumpjumper, we pursued some hefty goals. It had to excel on any kind of trail, for every style of rider. To achieve that, we went after serious weight reduction without sacrificing durability, a stiff, responsive chassis that still rides light and lively, geometry that improves everyone's riding, and the best suspension kinematics we know how to design. Turns out, you can have your cake and eat it too with the new Stumpjumper. - THE SWEETEST 130MM OF TRAVEL YOU'LL EVER RIDE - We massaged the kinematics of the Stumpjumper suspension to bring out the very best all-round performance possible in a 130mm package. Countless hours of suspension lab development and field testing created a refined mid-travel ripper that eats big terrain like a gravity fed beast, handles like a dream everywhere, and climbs like it has a motor. - PROGRESSIVE GEOMETRY - The S-Sizing geometry of the new Stumpjumper hits the progressive sweet spot. It's long, low and slack, with a short offset fork and a steeper seat tube angle. These numbers combine to make your ride more stable, more carvealicious, more comfortable climbing, more better everywhere. With FlipChip adjustability you're able to further fine-tune your fit, ensuring that your new Stumpjumper performs flawlessly on whatever terrain you choose. - RIDER-FIRST ENGINEERED - Rider-First Engineered frames use a size-specific approach to ride characteristics that ensures benchmark handling and flawless performance, regardless of frame or rider size. Whether you're a jump-happy grom riding an S1, or a DH-fiend giant in need of the lengthy S6, you'll experience the same ride traits - rail-sharp cornering and balanced front and rear stiffness - at the lightest-possible weight, And by light, we mean real light: 2,250 grams (S-Works, S-3 size, with rear shock).
