Mountain Frames

The S-Works Stumpjumper EVO is much more than just a trail bike; it's a shred-sled built to full-send down the gnarliest trails. 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. - All the travel in the world is useless without the proper shock tuning and kinematics. For the new Stumpjumper EVO design, we prioritized kinematic performance. Applying lessons learned while developing the Enduro, then following that with more than 1,000 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 we further improved bump performance on square-edge hits. Bottom line? This thing shreds trails, not legs. - 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. - The S-Sizing geometry of the new Stumpjumper EVO is our most progressive yet. Long, low, slack, short offset fork, steeper seat tube angle these are requirements for modern progressive riding. But not everyone jibs the same way, which is why the geo on the new Stumpjumper EVO is fully adjustable with six different settings. You can adjust the BB height by 10mm, you can adjust your head angle by two-degrees, and you can make these adjustments independently of each other. Finally, if you want to go full-party mullet-mode, the EVO lets you run a 27.5-inch rear wheel mated with a 29-inch front. - We introduced the SWAT door on the Stumpjumper in 2016, adding room IN your frame for those "oh sh**t" necessities like pumps and spare tubes, and immediately rendering jersey pockets redundant. With the new Stumpjumper, we have increased the volume and added a SWAT Bladder, giving you an extra 22oz of water storage, the same size as a small water bottle, hidden in your downtube.

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 S-Works Stumpjumper frame is the perfect starting point for you to envision your own interpretation of the Ultimate Trail Bike. Start with our supremely light, incredibly strong, FACT 11m carbon frame. Then dress it to suit your needs, whether those needs be singletrack soul surfing or death-grip mayhem. - 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). SWAT—We introduced the SWAT door on the Stumpjumper in 2016, adding room IN your frame for those “oh sh**t” necessities like pumps and spare tubes, and immediately rendering jersey pockets redundant.

Let's get something clear, the Stumpjumper EVO Alloy isn't a "normal" trail bike. It's built to get gnarly, plain and simple. Featuring the same all-new design as its carbon brethren including an adjustable head tube angle, 150mm of performance tuned travel, the adaptability of S-Sizing, and SWAT Door integration in a lightweight yet tough M5 Alloy chassis, you're going to be able to bomb down trails that you thought you couldn't touch without a full-blown DH rig. - All the travel in the world is useless without the proper shock tuning and kinematics.

The all-new Chisel has been purpose-built to tackle modern cross country trails and race courses with the utmost speed. In fact, it shares many of the same modern features as its Epic Hardtail sibling, but in a more budget-friendly package—making it the most efficient and capable alloy hardtail out there. And with this frame option, you can build your new Chisel exactly how you like. Top-end build for a durable XC shredder? Oh, yeah. Or maybe a budget-friendly one that you can upgrade later? Easy. The Chisel frame is the perfect canvas to start painting your new path to XC racing. - We asked ourselves, "How do we bring pro-level performance down to a price more riders can afford?" D'Aluisio Smartweld Technology, that's how. Smartweld allows us to create the most consistent, high-strength welds possible while taking full advantage of compliant, hydroformed alloy tubes. The result? One of the lightest alloy hardtail frames out there at 1,350g, which also features size-tuned stiffness. - The new Chisel also houses all of the modern features that you expect from an XC bike, like Progressive XC Geometry with a 68-degree headtube angle and longer reach, internal cable routing, a threaded bottom bracket, boost spacing, 30.9mm dropper post compatibility, and 1x-only drivetrains.

It's dealer's choice with the Status 160 frameset, but whatever the build, a good time is more than a safe bet. But that said, the odds of you being able to keep your poker face after getting a taste of the Status 160's playful Mixed Wheel-Size Trail Geometry are awfully tall. - With an eye on keeping maintenance to a minimum, oversized pivot bearings increase durability while a common size across all pivots makes service and replacement a breeze when that day does come around. A threaded SRAM DUB bottom bracket continues on the theme with worry-free performance. - The active, planted feel of the Status's FSR suspension design and Fox's FLOAT X Performance rear shock equipped with our Rx Trail Tune make for perfect friends—and plenty of benefits. Calling on a twin-tube design that allows for two separate oil pathways during compression and rebound, the FLOAT X Performance rear shock provides plenty of support for big hits while still offering enough buttery small-bump sensitivity to keep you fresh for when the style points really count.

The Chameleon is a blank canvas, ready to go in whatever direction your imagination takes it. Creativity in wheel size, gearing and component choice make it the perfect muse for freethinkers and freedom seekers alike. We made the Chameleon for riders who like to sculpt their ideal bike, and aren't afraid to experiment. Whether 29er or mixed, geared or fixed, multiple major configuration transformations are made easy via the interchangeable dropouts. The low slung top tube and progressive geometry means this bike blends into whatever surroundings you place it. From raucous short-cuts across town to skipping the city altogether. It turns itself to trail exploration with the flip of an Allen key, thanks to the triple-bolt cargo cage mount under the downtube and standard bottle mount within the frame. Whatever the weather, however long the ride, wherever you're going, the Chameleon is so endlessly customizable and adjustable that the only constraint is really your own mind and motivation.

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

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

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

The Ogre can get you to your job during the week, then way out of town on the weekend. It’s not sluggish on pavement or gravel and can also hold its own on singletrack. Ogre brings several sensible features to the 29er platform, including horizontal slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefy tire clearance. - 100% Surly Chromoly steel, double-butted main triangle - TIG-welded, Horizontal slotted with derailleur hanger, Gnot-Boost spacing allows the use of 135mm QR hub, 142 x 12mm thru-axle or 148 x 12mm Boost hubs. Features Rohloff torque arm slot and threaded eyelets for fenders, racks and Surly trailer mounts - Full-length Surly Trip Guide housing line guides for derailleurs and brakes; two sets of bottle cage mounts; upper seatstay threaded barrels, 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 - Disc brakes only. Disc mounts are 51mm IS. Note: rear disc brake is limited to 160mm maximum rotor diameter and requires the use of Surly caliper adaptor (included with frames and bikes) - Frame is E.D. coated for increased life expectancy - Tire clearance for 29 x 2.5" or 27.5 x 3"

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 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. "Any day of the week's a great day to ride a Wednesday." - Modern mountain standards: stealth dropper post routing, 44mm headtube, suspension correction, front and rear thru-axles - Full suite of useful braze-ons: front and rear racks, multiple sets of three-pack mounts, fenders - Full-forward, short chainstay position: 26 x 3.8" tires on 80mm rims; full-rearward, longer chainstay position: 26 x 4.6" tires on an 80mm rim Specs: - Rear Dropout Configuration: Horizontal slotted with optional vertical dumpout - Rear Hub Spacing: 12 x 177mm (Surly axle included); 10 x 170mm with Surly 10/12 Adapter Washers (not included) - Front Hub Spacing: 15 x 150mm (Surly axle included) - Rear Brake: Disc - 51mm I.S.

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.

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

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.

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.

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 2.8" 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, 29 Trail EVO geometry, and 140mm 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.
