Mountain Frames

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. This frame also includes a custom Ohlins STX rear shock with our venerable, easy-to-set-up AUTOSAG system. - FACT 11m carbon fiber Trail Chassis with Stumpjumper FSR full carbon rear end blends stiffness with light weight to form the pinnacle of efficiency, while fully enclosed cable routing and an integrated SWAT Door create exceptional handling and zero-hassle storage. - 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.

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.

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

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 judgement 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. A Smarter BRAIN 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. Frame-Changer 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.

And the Stumpjumper EVO Frameset is the perfect starting point to build your own version of the ultimate trail bike. - 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 SWATG 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 SWATG Bladder, giving you an extra 22oz of water storage - the same size as a small water bottle - hidden in your downtube.

Go fast, get rowdy and nail new lines. With a full-composite chassis, developed with Giant's enduro racing pros, this hard-charging 29er has 160mm of maestro rear suspension, adjustable geometry, and the option to switch to a 27.5-inch rear wheel. KEY PERFORMANCE FACTORS: - Race-bred suspension A Maestro rear suspension system with 160mm of travel, paired with a 170mm fork, was developed and tested under the extreme conditions of Enduro World Series races. The trunnion mount shock has a longer stroke (62.5mm compared to 60mm on the previous gene - Adjustable enduro geometry Flip chip technology lets you switch between three settings depending on the terrain. You can select a 63.5, 63.9 or 64.2-degree head angle and corresponding 78.3, 78.7 or 79-degree seat tube angle, resulting in a 35, 30 or 25mm bottom bracket drop (size - Rear wheel options Riders can choose either the stock 29-inch rear wheel or switch to 27.5. The larger 29-inch option improves stability and roll-over capabilities, while 27.5 delivers a more agile, snappier feel. It's a quick and easy way to adjust the bike's handling and TECHS & FEATURES: - ADVANCED COMPOSITE TECHNOLOGY Giant's High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction. - ADVANCED FORGED COMPOSITE TECHNOLOGY A state-of-the-art high-pressure molding process is used to produce complex-shaped carbon fiber components that are lighter, stiffer and stronger than similar components made from aluminum. This technology is used in critical performance parts such as Maestro Suspension rocker links. - MAESTRO SUSPENSION TECHNOLOGY Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail. - OVERDRIVE Giant's original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system's oversized headset bearings (1 1/4" lower and 1 1/8" upper for road, 1 1/2" lower and 1 1/8" upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness. - TUBELESS SYSTEM Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant's Tubeless System makes it easier than ever to experience all these benefits. - FLIP CHIP - MAESTRO The flip chip allows riders to quickly adjust the geometry of their Maestro-equipped mountain bike to better suit how and where they ride. It lets riders change the headtube/seattube angles and bottom bracket height via eccentric (offset, two-position) hardware located on the upper rocker arm.

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.
