Mountain Frames

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.

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.

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.

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.

We know full well that for many out there, the ultimate trail bike needs to possess the agility and responsiveness that comes with 27.5-inch wheels. We tend to agree, which is why developed the S-Works Stumpjumper 27.5. The frame-only option, in our eyes, represents the pinnacle of trail performance, and it lets you build your dream Stumpy exactly how you like it. Starting at the carbon layup, it features our highest-end FACT 11m for an ultra-lightweight, strong, and stiff construction. The carbon molding process also allowed us to revolutionize how you carry your trail essentials with the SWAT Door found at the down tube. This compartment will fit a tube, a tool, and pump without rattling or compromising the structural integrity of the frame. You'll also find an aggressive and super nimble geometry that complements 650b wheels and features ridiculously short chainstays, a roomy top tube, a low bottom bracket, a slacked out front end, and our proprietary Rx Trail Tune at the rear shock.
