Mountain Frames

THINK FASTEST: The Epic World Cup is the fastest XC race bike in the world on smooth to moderately technical courses thanks to its unmatched combination of efficiency, control, and light-weight. World Champ Christopher Blevins said it best, "This thing gives me everything I could want from a hardtail, plus the control and capability of full suspension." All it took to create this speed machine was a totally integrated development approach, inventing a radical new shock, and four decades of off-road winning experience. FRAME OF REFERENCE: To deliver maximum speed through ruthlessly efficient power transfer and precision handling, our engineering team set and achieved new standards in torsional rigidity and BB stiffness. This feat required an integrated development approach that merged a structurally superior double diamond layout with its shock cradled inside the top-tube, and finished off with the most sophisticated composite layup in Specialized history. SHOCKINGLY FAST: The Specialized Ride Dynamics team conceived of and invented a revolutionary shock technology for the Epic World Cup that gives the rider the efficiency and snappy response of a hardtail PLUS the control, capability, and momentum-carrying of full suspension-all with a simple setup. Co-developed with RockShox, the SID Deluxe WCID shock utilizes a unique independently adjustable positive and negative air springs to deliver the sought-after hardtail "snap", combined with terrain-devouring forgiveness, and the ability to easily personalize set-up for a specific course or tune for rider preference and feel. Set it firm and it rides like a hardtail or open it up and you have a chunk-squashing ripper. But you aren't just limited "open and closed," the simple nature of its setup allows the rider to set on a spectrum of firm to soft. PUNCHING ABOVE ITS CATEGORY: The Epic World Cup's 75mm of rear travel delivers control and capability of a much longer travel bike. Because it's designed to be ridden at or close to topped-out, it yields the same positive travel as a 100mm travel bike set up with 25% sag. To further optimize suspension performance, the Specialized Ride Dynamics team tuned the spring-rate to be relatively flat through the mid-stroke to handle the majority of bump forces like a longer travel bike. Due to its large size, the custom Mega Jounce Bumper is an "industry first" and plays a crucial role in smoothly managing bottom-out on the biggest impacts. HAVE WE LOST OUR MINDS? SORT OF: While the new, and groundbreaking SID Deluxe WCID shock provides the unique blend of support and compliance in the rear, the BRAIN is still alive and well in the fork. Its Position-Sensitive technology allows riders to sag into the fork 15mm for a balanced ride, providing supple small bump compliance and a firm pedaling platform without the need for a remote lockout or levers to flip. THE WEIGHT IS OVER: With a frame weight of just 1,765 grams (painted with shock and all hardware), the Epic World Cup edges out the lightest of competitors. This translates to faster acceleration, more efficiently climbing, and more agile handling. And all of that adds up to speed. We achieved the featherweight and monster stiffness of the Epic WC by applying what we learned in the development of our Aethos, the lightest production road frame ever made, specifically the advanced composite layup and tube shapes. THE BIGGEST FLEX IS NO FLEX: The Epic World Cup Frameset sports the 180-gram Roval Control SL seat post, boasting peerless light-weight, stiffness, and control on the World Cup today. - The all-new Epic World Cup frame features Ride Dynamics Developed suspension technology and 75mm of optimized rear wheel travel. Thanks to its shock technology, Epic World Cup delivers unmatched pedal efficiency and is ready for the roughest descents you can throw at it–no lockout switches required. - An all-new Control SL seatpost is amongst the lightest off road seatpost in market, further shaving grams to get riders up the climbs as effortlessly as possible. - An all-new SID SL BRAIN fork provides 110mm of bump muting performance while discerning inputs from the ground or rider to provide ultimate efficiency.

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?

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.
