Mountain Frames

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.

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

DH is all about speed—that's true whether your aim is to climb the podium or to simply bring home all the bragging rights after a day at the park. If speed is what you're after, the Demo Race 29 is your sled. Everything about this bike is designed to get you from zero to Mach 10: a new frame design, improved kinematics, better braking, big wheels, and all today's newest fancy bits. It's time to get rowdy. We've refined the Demo's kinematics and suspension design. We had one overriding goal—improve the bike's ability to carry momentum, no matter how technical the terrain. More momentum equals more speed, after all. The revised axle path reduces hang-up on square-edged bumps and that, in turn, transfers more energy to the suspension and less to you. While we were at it, we also improved the Demo's suspension performance under braking and added a bit more anti-squat to improve its pedaling performance. Bottom line, the new Demo rolls faster through chunky terrain than its predecessor. To get your dream build started off right, the frame includes an Öhlins TTX rear shock with 200mm of travel, a 225x75 Trunnion mount, and high- and low-speed compression adjust. Finally, no DH rig would be complete without a Thomson seatpost, so yeah, we threw that in there, too. - M5 alloy construction works in harmony with our Style-Specific DH Geometry to create the ultimate race machine. The design is compact in order increase maneuverability and responsiveness, while the 200mm of travel at the rear makes the bike capable of taking big hits in stride. And to fill out all of the details that make the difference on race day, we’ve included an ISCG ‘05 mount for chain guides and all the bits to make it easy to work on. - Custom Ohlins TTX Trunnion 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 has 200mm of coil-sprung travel that stands without rival, and you won't find it anywhere else. - The Body Geometry Henge DH saddle features our proven Body Geometry design, and implements a cutout on the underside for added rear tire clearance.

The Rebel Yell of the middle child. Fed a steady diet of super-tech climbs, the SB130 was built to crush the biggest terrain. No trail is "too" anything. Point it up or down. Enter a last-minute enduro just for the fun of it. We like to say no one bike can rule it all. But the SB130? It's one bike that rules. - At the heart of the SB130 suspension design is our patented Switch Infinity suspension system. - The SB130 is built to tackle any type of terrain. From buffed out singletrack, to rugged EWS racecourses, it can hold its own on a huck. - The SB130 has progressive trail-inspired geometry. We took what we learned from the SB5 and our Factory team riders and incorporated it here. - A patent-pending wishbone shock extender was developed to change the leverage ratio and shock clearance. - No more gunk on your water bottle mouthpiece, as the mount is now inside the front triangle. - An integrated headset allows for a lower overall stack height and cleaner carbon layup. - Internally tunneled routing allows for clean lines, ease of maintenance, and less shifting of housing during suspension movement. - Switch Infinity utilizes a patented translating pivot that switches direction as the bike moves through its travel. - Our linear system built by FOX is able to achieve infinite tunability and durability, which cannot be matched by traditional link designs. - Decoupling of the chain forces allows the suspension to work more efficiently to absorb impacts. - The ability to manipulate the leverage ratio without affecting the anti-squat characteristics is unique to Switch Infinity suspension. - C-Series frames utilize small changes to the carbon fiber layup to offer a more aggressively priced carbon frame.

Santa Cruz's 5010 CC is more than just a bike—it's a well crafted, trail-slaying tool. It features VPP suspension providing 130mm of ground-gripping action to tackle the steeps, the drops, the bumps, and the curves. A low bottom bracket and short chainstays translate into a snappy ride, while CC carbon construction makes the 5010 as light and stiff as possible. Throw in a 142mm rear axle, forged upper and lower links, double-sealed pivots, lower link grease ports, and angular contact bearings for lateral stiffness that will have you howling through the corners. It's topped off with ISCG-05 tabs and internal cable routing for your dropper post.

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 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. 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. - Custom Micro Brain shock offers easy tuning and unrivaled efficiency - Our custom RockShox SID WC fork with Brain features a full-carbon upper, top-adjust Brain Fade, and a custom offset, making it the perfect match to the new Epic.

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

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.

The Stumpjumper EVO Carbon 27.5 has one goal—to conquer the gnarliest trails out there. Ultralight yet ultra burly, the carbon chassis is configured around a seriously slack, long and low geometry that make this the perfect foundation for a featherweight bruiser of a bike. ONE FRAME, ANY TRAIL The innovative sidearm frame design makes a lighter, better-handling bike. By directly connecting all three mounting points of the rear-end and shock to the frame, we’ve increased both stiffness and performance over bumps. EVO IS FOR SHREDDERS Stumpy EVOs aren’t "normal" trail bikes—they’re built to get gnarly, simple as that. With their slacked-out front-end and longer top tube, EVO models have heavier steering and exceptional front-end traction that beg you to do cutties and boost every lip. Get rowdy. THE PERFECT FOUNDATION - Lightweight, carbon chassis offers the perfect balance of stiffness and precision handling. - Built to shred with 27.5 Trail EVO geometry and 150mm of rear suspension. - FOX FLOAT DHX2 Performance Elite rear shock boasts stellar big-hit performance.

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

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.

It's hard to top the history and beauty behind a Troy Lee Designs paintjob, and what's on display on this limited-edition, EVO Stumpjumper chassis pairs slack, long and low geometry with 140mm of deep and progressive suspension. It's a featherweight brawler. One frame, any trail The innovative sidearm frame design makes a lighter, better-handling bike. By directly connecting all three mounting points of the rear-end and shock to the frame, we've increased both stiffness and performance over bumps. Evo is for shredders Stumpy EVOs aren't "normal" trail bikes—they're built to get gnarly, simple as that.

You lie in bed at night and dream of a bike that can really do it all—climb the tallest backcountry passes with ease, tear through the rootiest, rockiest tracks, and slingshot out of corners when you get on the gas. Wake up meet Santa Cruz's Hightower CC Frameset. It's CC-carbon construction is as light, responsive, and strong as it gets, while the 135mm VPP suspension, compliments of the RockShox Monarch rear shock, annihilates any and all terrain that gets in your way. These combine to give the Hightower the versatility to deal with whatever appears on the horizon and seamlessly adapt to the trails and style you ride, from the rocky peaks of the Dolomites to the rain forest of British Columbia. The headtube angle and longer reach combine to create a dreadnought that can roll over anything that dare lay in your path.

Last we checked, "XC-style" racing on a mountain bike doesn't stop once you crest the climb. Crushing souls on the descent is more than half the fun. And a hell of a lot more than half the point. For racers who want to fly down as much as soar up, the SB100 is the bike we've always wanted to make. - The Switch Infinity was re-designed for 100mm of travel, it's lighter and tucks neatly behind the seat tube. Pretty rad. - The new frame designs accommodate a water bottle mount in the front triangle and allow space for longer dropper seat posts. - SB100 features genre-killing geometry, inspired by going fast downhill but balanced to provide uphill efficiency. - An integrated headset allows for a lower overall stack height and cleaner carbon layup. - Internally tunneled cable routing allows for clean lines and a quiet, rattle-free ride. - Switch Infinity utilizes a patented translating pivot that switches direction as the bike moves through its travel. - Our linear system built by FOX is able to achieve infinite tunability and durability, which cannot be matched by traditional link designs. - Better "decoupling" of the chain forces allows the suspension to work more efficiently to absorb impacts. - The ability to manipulate the leverage ratio without affecting the anti-squat characteristics is unique to Switch Infinity suspension - TURQ Series bikes are made with the highest quality carbon fiber available and offer the perfect balance of stiffness and compliance.

If you’re looking to build the fastest, most capable enduro race bike, you can’t do better than the model that defines the very genre. The S-Works Enduro’s blissfully tackles the kind of terrain that chews up and spits out lesser bikes. Full-carbon linkage shaves 250 grams off the already ultra-light, carbon chassis. INCREDIBLY CAPABLE If the Enduro looks like its sibling, the Demo, it's because they share plenty of downhill DNA. The Enduro rolls fast on 29er hoops and boasts 170 millimeters of front and rear suspension courtesy of an all new-design that obliterates the biggest hits with ease. ASTONISHINGLY FAST...UP AND DOWN THE TRAIL Stomp on the pedals and the new Enduro accelerates far quicker than you're expect possible from a downhill bruiser. We pulled out all the engineering stops and made the Enduro an incredibly efficient pedaling machine. The end result? Less bobbing. More speed. - All-new design boasts 170 millimeters of suspension. - FOX FLOAT X2 Factory shock offers unrivaled big-hit control and on-the-fly adjustability. - Ingenious SWAT Door downtube storage system, threaded bottom bracket, and internal cable routing.

Let's get something clear—the Stumpjumper EVO Alloy 27.5 isn't a "normal" trail bike. It's built to get gnarly, and there's no real way around that. It has a slacked-out front-end and a longer top tube, so the EVO has heavier steering and exceptional front-end traction that begs you to do cutties and boost every lip. And with the perfect blend of responsiveness and stability that 27.5-inch wheels are known for, you'll be shredding the gnarliest lines in no time. When the goin' gets rowdy, the rowdy get goin'. What exactly is the EVO for? EVO is for the shredders—the gnarliest trail riders who live for gravity riding. Big drops, huge kickers, rocks, roots—whatever you throw at it, the Stumpjumper EVO can handle it. EVO uses the same style-specific sizing that's featured on our Demo. This sizing lets you choose the bike that fits the way you ride—not just by the seat tube measurement like with most bikes—and it narrows things down to two sizes, S2 and S3. These are longer, lower, slacker, and have seat tube and head tube heights that allow you to choose the size that best suits your style and terrain. Our other design goal was simple—build the ultimate trail bike. One that feels telepathic. And it turns out that this feeling all comes down to stiffness. Think of it this way: when the frame's telling your hands one thing and your feet another, your brain gets confused with the imbalance and the bike feels unstable. In order to fix this, we had to get to work on dialing-in the materials and shapes. We continued down the suspension path with a custom Rx Trail Tune on both the fork and rear shock. Suspension performance is highly dependent on frame, wheel, and rider size, so we use our Rx Tune to get each bike to land in the middle of the adjustment spectrum, and this gives you the biggest possible range to fine-tune your ride. Another focal point of the tune was matching the suspension characteristics between wheel sizes—we developed a specific Rx Tune for each platform. So, no matter what wheel size you prefer, you'll get perfectly linear suspension. Steps were also taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, and we made room for up to a 3.0" tire. You're also free to run whatever aftermarket rear shock you want, since we're using standard metric shocks. And customization is furthered with a Flip Chip that lets you to dial-in your Stumpy to your riding style. Switch it from High to Low and it drops your bottom bracket 6mm and slackens the head tube by half-a-degree. Little details also jump out to surprise you, like a newly designed ribbed chainstay protector that makes chain slap a thing of the past and nearly silences the drivetrain. - With its M5 alloy frame, 27.5 Trail EVO geometry, and 150mm of travel, the Stumpjumper EVO Alloy has been purpose-built to shred the most gravity-defying trails. - FOX FLOAT DPX2 Performance has three modes—Open, Trail, and Firm—that control large compression adjustments on-the-fly.

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.

Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. 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 singlespeed. 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) - Clearance for 26 x 3 or 27.5 x 2.8 tires

The same chassis piloted to riotous success in its very first season on the World Cup circuit, the Demo Race frameset brings 27.5/29-inch rear wheel compatibility to the fore in the search for the optimal balance of speed, traction, and maneuverability while allowing for unmatched versatility. RockShox's proven Super Deluxe DH Coil gives you a head start on suspension perfection, just hang your time-tested race kit before you pick up the search where we left off, and there's a good chance you'll find a few podiums along the way. - The Demo Race M5 alloy frame is fully optimized to take advantage of the traction benefits of a 29-inch front wheel and the increased maneuverability of a 27.5-inch rear wheel. And, it retains the ability to change your rear wheel size to suit different terrain and riding styles—the adjustable rear end ensures chainstay length and bottom bracket height stay dialed no matter the hoop size. - The Rockshox Super Deluxe Ultimate DH coil shock may be heavy on adjectives, but it's even heavier on performance, offering external low-speed compression and rebound adjustment while the Trunnion mount offers extra bushing overlap for increased durability.

Master of the gnarniverse. Bold claim. The SB165 was created to get after whatever you're getting after. The slackest sled in our lineup, with kinematics tuned for a coil-shock, the SB165 is at home outside the tape and trusted on the lines where mistakes can't happen. The SB165 already has you covered. - We wanted the SB165 to rip and have a poppy, maneuverable feel on the trail, so we built it around the 27.5" wheel platform. - At the heart of the SB165 suspension design is our patented Switch Infinity suspension system. Switch Infinity utilizes a patented translating pivot that switches direction as the bike moves through its travel. - Tuned to rip on the gnarliest trails, built tough to handle tosses and nasty tech, with kinematics specific for a coil or high-volume air shock. - The SB165 is designed to handle the steeps, so we made it low, long, and slack. - Better decoupling of the chain forces allows the suspension to work more efficiently to absorb impacts. - Chain Guide-ready out of the box with ISCG 05 mounts. - Internally tunneled cable routing allows for clean lines and a quiet, rattle-free ride. - An integrated headset allows for a lower overall stack height and cleaner carbon layup. - Our linear system built by FOX is able to achieve infinite tunability and durability, which cannot be matched by traditional link designs. - The ability to manipulate the leverage ratio without affecting the anti-squat characteristics is unique to Switch Infinity suspension. - TURQ Series bikes are made with the highest quality carbon fiber available and offer the perfect balance of stiffness and compliance.

Let's get something clear—the Stumpjumper EVO Alloy 29 isn't a "normal" trail bike. It's built to get gnarly, and there's no real way around that. It has a slacked-out front-end and a longer top tube, so the EVO has heavier steering and exceptional front-end traction that begs you to do cutties and boost every lip. And with all the speed that 29ers are known for, you're going to be able to bomb down trails that you thought you couldn't touch without a full-blown DH rig.

It's a featherweight brawler. One frame, any trail The innovative sidearm frame design makes a lighter, better-handling bike. By directly connecting all three mounting points of the rear-end and shock to the frame, we've increased both stiffness and performance over bumps. Evo is for shredders Stumpy EVOs aren't "normal" trail bikes—they're built to get gnarly, simple as that. With their slacked-out front-end and longer top tube, EVO models possess exceptional front-end traction that begs you to boost every feature on the trail. It's rowdy time. The perfect foundation - Limited-edition, EVO carbon chassis is stiff, precise, and rowdy. - Built to shred with 27.5 Trail EVO geometry and bottomless-feeling rear suspension. - FOX FLOAT DHX2 Performance Elite rear shock boasts stellar big-hit performance.

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. Our 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. We’ve also adorned this frame with our Gnot-Boost spacing, allowing you to use any mountain bike hub whether it be 135mm QR, 12 x 142mm thru-axle, or 12 x 148mm Boost hub. The chainstay yoke has been redesigned to be fully compatible with 26+ tires and 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. Man has known for eons the call of the indifferent forest. The inexorable march of time, and dumb crap like cell phones, have dulled our senses and made us afraid. Reclaim your animalistic tendencies atop Man’s greatest invention.

The Stumpjumper EVO Carbon 29 has one goal—to conquer the gnarliest trails out there. Ultralight yet ultra burly, the carbon chassis is configured around a seriously slack, long and low geometry that make this the perfect foundation for a featherweight bruiser of a bike. ONE FRAME, ANY TRAIL The innovative sidearm frame design makes a lighter, better-handling bike. By directly connecting all three mounting points of the rear-end and shock to the frame, we’ve increased both stiffness and performance over bumps. EVO IS FOR SHREDDERS Stumpy EVOs aren’t "normal" trail bikes—they’re built to get gnarly, simple as that. With their slacked-out front-end and longer top tube, EVO models have heavier steering and exceptional front-end traction that beg you to do cutties and boost every lip. Get rowdy. THE PERFECT FOUNDATION - Lightweight, carbon chassis offers the perfect balance of stiffness and precision handling. - Built to shred with 29er Trail EVO geometry and 140mm of rear suspension. - FOX FLOAT DHX2 Performance Elite rear shock boasts stellar big-hit performance.

The S-Works Epic Hardtail is the lightest production frame to date. Impressive, yes, but it's much more than that. We've also created the most capable and comfortable cross-country machine ever, because you're not fast if you're being pummeled by the trail. It's a game changer. - At 775 grams, the new S-Works Epic Hardtail chassis is the lightest production hardtail frame on earth. What’s more, we’ve designed it to be incredibly capable and comfortable, with progressive geometry and an advanced composite layup that boosts vertical compliance. We’ve optimized every inch of this frame, precisely tailoring the carbon and resin mix to create the perfect balance of weight, strength and compliance. We’ve gone full geek on the S-Works frame, obsessing over the shape of every overlap layer. While 3-D tailoring an overlap probably sounds like overkill, the extra time and labor spent doing it allows us to eliminate extraneous composite plies that were adding weight, but not improving strength. In other words, there’s a science to the weight savings.

"Race bred." It's not just a slogan printed on the SB150's top tube. We've been pinning on numbers and pinning the throttle since 1985. So when choices had to be made on the SB150, every single one was made in the name of unbridled speed. It represents the ultimate example of breeding a bike to beat the clock. - At the heart of the SB150 suspension design is our patented Switch Infinity suspension system. - Tuned to perform on the most grueling enduro tracks in the world. - Built Richie "F-ing" Rude tough, this frame meets Yeti DH testing standards. - The SB150 has progressive, enduro-inspired geometry. We took what we learned from our EWS team riders and made it low, slack, and long. - A patent-pending wishbone shock extender was developed to change the leverage ratio and shock clearance. - The water bottle fits comfortably inside the front triangle, where you might be used to looking for it. - Internally tunneled cable routing allows for clean lines and a quiet, rattle-free ride. - TURQ Series bikes are made with the highest quality carbon fiber available and offer the perfect balance of stiffness and compliance.

Some say the SB140 never met a dirt it didn't like. We agree in spades. What's your pleasure? Drag a bar. Make an edit. Stay out after dark. Try it. Land it. Or just stay at it. Happy to pedal, greedy for more—the SB140 is down for fun. - At the heart of the SB140 suspension design is our patented Switch Infinity suspension system. - We've tuned the SB140 for maximum fun on the trail or at the park. - The SB140 is designed to help you get the wheels off the ground. - An integrated headset allows for a lower overall stack height and cleaner carbon layup. - No more gunk on your water bottle mouthpiece, as the mount is now inside the front triangle. - Internally tunneled cable routing allows for clean lines and a quiet, rattle-free ride. - Switch Infinity utilizes a patented translating pivot that switches direction as the bike moves through its travel. - Our linear system built by FOX is able to achieve infinite tunability and durability, which cannot be matched by traditional link designs. - Better decoupling of the chain forces allows the suspension to work more efficiently to absorb impacts. - The ability to manipulate the leverage ratio without affecting the anti-squat characteristics is unique to Switch Infinity suspension. - TURQ Series bikes are made with the highest quality carbon fiber available and offer the perfect balance of stiffness and compliance.

Santa Cruz's Jackal is brutally simple and built for sending it into the air. This aluminum ride is all about short, stiff chainstays and seatstays, and the right feel when launching off a head-high wall of dirt. The top tube is low so it stays out of your way when throwing your legs over it. And, this rig is built stout, so it can stomp landings all day long and come back for more when you don't stick it. Adjustable dropouts let you switch easily between gears or singlespeed and you've got ISCG05 mounts, too.
