Whether your goal is to escape on gravel back roads, far from cars and crowds, or drop the hammer at the front of your favorite gravel race, no bike does it better than the Diverge. It's quite simply the fastest, most capable—and just maybe the most fun—bike we've ever made, delivering a ride that's quick and lively under power, but stable and confidence-inspiring when the terrain gets rough. From Future Shock 2.0 and all-new gravel geometry to internal storage and category-leading tire clearance, the Diverge represents everything we've learned over more than 40 years of riding road, gravel, and dirt. The Diverge writes an entirely new chapter in the gravel bike category, so you can dream up entirely new rides. It's the ultimate getaway vehicle. With a FACT 9r carbon frame and Future Shock 2.0, the Diverge Expert will have you riding faster and more confidently over more terrain than you ever imagined possible. Shimano's gravel-inspired GRX Di2 1x11 group puts all your gears in reach with a quick click, while the DT Swiss G540 alloy wheels, mated to Pathfinder Pro 38mm tires, ensures performance across smooth pavement, dirt roads, and gravel tracks. A Roval Terra seatpost keeps the Diverge Expert perfectly balanced for the ultimate ride. - Nothing unlocks a bike's capability like tire clearance, so we gave the new Diverge a whopping 47mm of tire clearance with a 700c wheel and 2.1-inch with a 650b wheel. Thanks to a drive-side chainstay utilizing a solid beam of carbon behind the chainrings, we've created clearance without using a fragile dropped chainstay design or increasing chainstay length. - Speed, control, and confidence—Future Shock 2.0 is the ultimate technology for the gravel rider. With 20mm of axial compliance and a hydraulic damper, Future Shock 2.0 suspends the rider, not the bike. This keeps you confident and in control, able to keep the power down and stay off the brakes over rough dirt roads and in thick loose gravel, all while keeping your hands, arms, and neck fresh. Since Future Shock 2.0's damper is adjustable, you'll be ready for the rough stuff and efficient on smooth pavement. - The more capable your bike, the bigger your rides get, so Diverge borrows SWAT internal storage from the legendary Stumpy. The SWAT door lets you utilize space in the down tube to store tools, a flat kit, nutrition, and even our SWAT Jacket. It keeps weight off your body, low in the bike for better handling, and makes you more self-sufficient, so get out there. SWAT's got your back. - We tossed gravel geometry "status quo" out the window. The new Diverge has the most progressive geometry we've ever created for a drop bar bike, giving riders a capable and stable bike in the dirt, that still feels responsive and nimble on the road. We've increased the frame's reach and introduced a slacker head tube and a longer offset fork. All this creates incredible confidence with a planted feeling in the dirt, while spec'ing shorter stems keeps the overall cockpit length the same and the steering lively. We've kept the bike's BB low to increase stability, but high enough to utilize with 650b wheels if that's your jam. - We've given the Diverge plenty of rack mounts, including fork and top tube mounts, to ensure you can take what you need, no matter how far you plan to go or how long you plan to stay out. - With a FACT 9r carbon frame, the Diverge Expert frame is incredibly capable and race bike light. Pin it for your local dirt climb KOM, or grind up a giant backcountry peak, the light and lively Diverge will get you there faster.

The geometry of the Advanced composite frame and swingarm was developed specifically around 29-inch wheels. That means shorter chainstays, a longer toptube, and just the right angles with the headtube (64.56 degrees) and seattube (76.36 degrees). We gave it an updated Maestro rear suspension system with 146mm of travel. The trunnion mount shock and Advanced Forged Composite rocker arm deliver an active, super plush feel on the trail.

Shred hard and shred fast with this lively 29er. It's built on an all-new full-composite frame with adjustable geometry, giving you smooth control to blitz technical trails at speed. This versatile trail bike features a full composite frame that's fitted with a new Maestro suspension system that has 5mm more travel than the previous generation. The Advanced Forged Composite rocker arm has a flip chip that allows you to adjust frame geometry. Choose steeper or slacker headtube/seattube angles and either a 35mm or 45mm bottom bracket drop to adjust the handling for your riding style and terrain.

The fastest downcountry bike in the world. Epic 8 EVO is the dressed up, cranked-to-11 expression of the new Epic 8. Spec’d to slay downcountry terrain with its unmatched combo of capability, efficiency, and light weight, Epic 8 EVO’s updated kinematics allow for insanely efficient climbing—while the Ride Dynamics-tuned shock eats up rough terrain on the way down. If ripping single track at blazing fast speeds and high fiving your friends is your idea of fun, the Epic 8 EVO is the bike for you. UNMATCHED CAPABILITY: The most capable 120mm bike on the planet, made even more capable. You’ll be blown away by how Epic 8 EVO’s progressive geometry delivers technical terrain capability alongside fast and efficient climbing and acceleration performance. The absurd lateral and torsional rigidity of the chassis translates to some seriously precision handling, too. With a bump up to 130mm of travel up front to eat up the chunk and a slew of trail-friendly specs, Epic 8 EVO feels right at home on the rough stuff. WHAT BUMP?: Compared to the previous generation, the new Epic 8 EVO absorbs 12% more bump and vibration forces, leaving you less fatigued and more powerful over time. That opens the options for another lap (or 3). RIDE DYNAMICS TUNED: The Specialized Ride Dynamics team developed custom valving for Epic 8 EVO’s new shock. Our team prescribes the special damping characteristics to holistically elevate the riding experience. By tuning the dampers alongside the chassis’ leverage rates and new kinematics, we’re able to deliver a bike that rides above the sum of its parts. BIOMECHANICAL EFFICIENCY: By optimizing the kinematics of the suspension, Specialized’s Ride Dynamics team reduced inefficient pedal-induced bobbing by 20%, maintaining active suspension for effective bump force management, to ensure you remain in the most efficient pedaling position. It’s the most efficient pedaling suspension bike we’ve ever tested. FULLY LOADED: All models now feature SWAT 4.0 to carry all your trail essentials, and an integrated steering stop to prevent the ubiquitous top tube scar the first time you crash and your bars spin. - The most capable 120mm bike on the planet. 12% more bump absorption and 20% less pedal bob - Ride Dynamics tuned FOX Float Performance and 130mm FOX 34 Performance fork - Lightweight and durable Specialized alloy wheels - SRAM’s legendary full-powered Code Bronze Stealth brakes make for a sleek cockpit and easy adjustments - Reliable and durable GX Eagle 12-speed groupset - SWAT 4.0 in down tube to carry trail essentials

With seven wins at Paris-Roubaix, our Roubaix has proven that Smoother is Faster. Until this moment, however, smooth has admittedly come with some compromises. But not anymore. The all-new Roubaix Comp now delivers compliance without compromise by introducing a radical new Future Shock 1.5 that gives you more control on rough roads, a new Pave seatpost that creates our most balanced Roubaix to date, aerodynamics that equal the Tarmac, and a Rider-First Engineered frame that's shed some serious weight. Is it still comfortable? Sure, but don't call it a comfort bike, because performance was behind every engineering decision we made. This is the new Roubaix. For the build, we spec’d the Expert with Shimano Ultegra Di2 for its powerful hydraulic disc brakes and super crisp 11-speed shifting. Of course, you’ll be rolling on sturdy wheels courtesy of a DT R470 Disc wheelset. - The new frame delivers compliance without compromise via the perfect balance of aerodynamics, light overall weight via a FACT 10r carbon construction, compliance, and Rider-First Engineering. With tube shapes that were born in our FreeFoil Shape Library and validated in the Win Tunnel, the new Roubaix is more aero than the Tarmac SL6. Meanwhile, to ensure the weight and ride quality, we turned to a Rider-First Engineered design to deliver optimal stiffness and compliance across all sizes, from 44 to 64cm. Of course, the frame has shed some serious weight in the process. And to prep you for your own Hell of the North, we've made room for 33mm tires. - To go along with the new frame, we've also developed a totally-new S-Works Pave seatpost. Not only is it the first compliant seatpost that's ALSO aerodynamic, it does so without any additional weight or finicky contraptions. Starting with the same D-shape design found on the Tarmac, we took its compliance a step further by building additional flex into the upper and developing a new drop-clamp design in the frame. This provides plenty of compliance while staying perfectly balanced with the front-end, so you get a smooth, balanced ride no matter how rough the road. - With 20mm of rough-road-taming travel, the Future Shock 1.5 not only delivers a smoother, more comfortable ride, but it also reduces fatigue and increases speed over harsh terrain. The new Smooth Boot, meanwhile, enhances the aesthetics to bring a clean transition from the head tube to the stem

We created the endurance road category two decades ago proving that high ergonomics means high performance. Today, the new Roubaix SL8 with Future Shock 3.0 is lighter, faster, and smoother than any road bike ever made, unleashing unmatched confidence. The road may be hell below, but on Roubaix, it's always heaven above. - COMPLIANCE: Future Shock 3.0 is the star of the show, more tunable, adjustable, and durable than ever. Now, regardless of position on the bike, every rider experiences 20mm of smooth, stiction-free travel between the stem and head tube. Future Shock helps keep your hands and bars steady for a smoother ride with more control to stay fast, safe, and confident. - Our dropped clamp design exposes more seatpost to increase deflection, but "more" isn't simply better. The Pave seatpost controls that deflection for the optimal vertical compliance. Together they create 'Cobble Gobbler' technology, and when paired with the Roubaix's rigid rear triangle, deliver a smooth ride with no loss in efficiency. - The Roubaix SL8 is the smoothest road bike our Ride Science Team has ever tested-reducing impacts at the bars and saddle by 53% vs. the nearest competition. With Roubaix's Future Shock 3.0 the wheel quickly moves over the bump, while rider mass remains stable, maintaining momentum in rough terrain. Typical forks deflect backward on impact, causing a measurable loss in speed. It's a scientific fact, smoother is indeed faster. - CAPABILITY: The Roubaix pioneered endurance geometry, so you ride "IN" the bike, not "ON" the bike to relieve pressure on your hands, arms, and shoulders for capability and confidence on any road, yet it's ready to dissect a mountain decent at full gas. Snuggle up. - With tire clearance up to 38c/40mm, this endurance road machine delivers better traction than ever on rough roads and even light gravel. Thanks to lightweight, super-efficient Specialized tires, that extra tire volume and traction comes with no downsides. - Roubaix inspires really BIG days on the bike, so we've given it every mount your adventures could need- three bottle mounts, top-tube mounts, and it's even fender-ready. So, go ahead and bring it all along for the ride. - PERFORMANCE: The new Roubaix SL8 is our most aero yet, with new aero shapes from our Free Foil library and dropped seat stays. At just 825 grams, the frame is 50 grams lighter, utilizing lessons learned from the Aethos—the world's lightest production frame—and our premium Fact 12r carbon blend. Nothing in its class is faster or lighter than the Roubaix.

Don't get us wrong, we're all for racing. Grand Tour top steps, Classic's Monuments-they're in our DNA. But sometimes riding simply to ride, riding for the love of riding, is just what we need. And this is what the Aethos lives for. Sure, it's given nothing up to performance and happens to be the lightest frame out there, but with no compromise to style. Aethos: Billions of calculations in the pursuit of one thing, perfect ride. And with this frameset, you have the perfect canvas to begin creating your dream ride. - The Aethos frame has been designed with the perfect combination of ultimate ride feel, lightweight, and style-from accelerating up steep pitches and descending technical descents, to all-day saddle comfort on even the longest coffee rides, the Aethos hits the mark. But how, you ask? By reinventing the traditional road shape found on bikes of the past, we've subtly altered these shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability. Pair that with an entirely new layup and process that we've perfected over multiple decades and you have the lightest frame out there (585 grams, S-Works, size 56cm). The Aethos is more than just a new bike, it's the first of a new breed. - A featherweight frame is useless without confidence-inspiring ride characteristics, which is why we've developed the Aethos to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flexing and breathing of carbon fiber, we were able to discover groundbreaking findings about how forces flow through frames. Just a few pedal strokes and you'll realize this sublime ride sets a new standard. - Every detail, from the derailleur hangers to the fork expander plug have been designed with style, weight, and durability in mind-everything in pursuit for the perfect ride.

The Enduro Expert has always packed a serious punch and it's never been so true. You get 170-millimeters of the most capable downhill performance that gains elevation with surprising ease. Full RockShox suspension, powerful disc brakes, and a robust alloy wheelset round it out. 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. 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.

What do you get when you pair a 29-inch front wheel with a 27.5-inch rear wheel? The Stumpjumper EVO LTD, that’s what. With all of the traction and handling benefits of a 29er, but with a smaller, more maneuverable rear wheel, this mullet setup suits a more jibby, playful style. It’s right at home at the bike park, and is a total blast to cut loose with on the trail. To enhance its 29/27.5” get-rowdy wheel setup, the Stumpjumper EVO LTD features a RockShox Super Deluxe Ultimate shock out back, paired with a RockShox Lyrik Ultimate fork. Top it off with 30mm-wide alloy wheels and a SRAM Eagle drivetrain, and the LTD is ready to party. - 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. - 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. - 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. - 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 Stumpjumper EVO Pro is a testament to full-gas trail performance. With an all-new design, from its S-Sizing geometry with an adjustable head tube angle, to its 150mm of shred-ready travel, this thing is a full-on ripper.
