Stumpjumper

The S-Works Stumpjumper 15 LTD trail bike is here to obliterate every trade-off in the trail game. Devour bumps like a big bike? Check. Short-travel control and optimal pedaling efficiency? Double check. Swapping between those two scenarios automatically without ever flipping a switch? Check, check, check. Meet the all-new S-Works Stumpjumper LTD with FOX Live Valve Neo.

KINEMATICS PERFECTED — As the quintessential trail bike, Stumpjumper 15 balances efficiency and optimal bump force management. For the anti-squat on Stumpjumper 15, we struck a balance between the previous Stumpjumper and Stumpjumper EVO, as both had excellent pedaling characteristics.

IT’S [A]LIVE — No, we haven’t finally created a sentient bike… It’s FOX’s brand new Live Valve Neo system equipped on S-Works Stumpjumper 15 LTD. A lightning-fast wireless rear suspension system that provides infinite tuning options through the FOX Bike app, and the best possible combination of XC pedaling efficiency and enduro descending capability—faster than the blink of an eye.

HONED GEOMETRY — This bike’s geometry delivers big bike capability when you need it, a nimble feel in tight sections, and lively, efficient climbing manners. The generous cockpit centers you on the bike, optimizing traction and corner control. The low bottom bracket, slack head tube angle, and optimized fork offset keep things stable in the rough.

RIDE YOUR WAY — The Stumpjumper 15 seamlessly integrates benchmark geo adjustability, making it the most personalizable trail bike ever. Six distinct geometry settings allow you to hone performance for any style, any terrain. Head angle and bottom bracket can be fine-tuned for stability or clearance.

FORM FOLLOWS FUN — We can make a frame as stiff as we want, but there’s such a thing as too stiff. To be one with the bike requires engineered compliance in the frame. We engineered the FACT 11M carbon—front end, rear end, and the link between them—as a single unit that hits the stiffness target we established for trail riding.

WHEEL CHOICE — With our aftermarket link shock links, you can choose between big wheels front and rear or mix things up with a 27.5” rear for a more responsive and playful ride. No matter what you choose, geometry is unaffected.

CARRY IT ALL — SWAT 4.0 on Stumpjumper 15 elevates downtube storage, an innovation we pioneered. It’s the smoothest operating, most weather-resistant, flush-mounted system ever.

MORE RELENTLESS THAN YOU — Our full-suspension bikes are built to be relentless, designed to endure years of hard riding, and backed by the best support and policies to keep you on the trail. Our unbeatable lifetime, no-questions-asked replacement suspension pivot bearings to the original owner (one bearing set, per bike, per year) is just one way we've got you covered. See your local Specialized Retailer for details.

Stumpjumper 15 is here to obliterate every trade-off in the trail game. Devour bumps like a big bike? Check. Short-travel control, playfulness, and efficiency? Double check. How about a heaping helping of personalization to make it perfect for the only rider who really matters—you?  Check, check, check.

BREAKTHROUGH CAPABILITY: GENIE Shock Technology combines a poppy, playful ride with a bottomless DH feel.

ULTIMATE CONTROL: Measurably better traction than “Bike of the Year” Stumpjumper EVO.

UNMATCHED PERSONALIZATION: Six-way geometry adjustment, mixed wheel or 29”, tunable spring curve, and more.

GENIE—The Magic Carpet Ride: The biggest innovation on the Stumpjumper 15 is GENIE. This patent-pending air spring technology that we invented grants every trail rider’s three wishes: the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable “platform” for a playful feel.

ILLUMINATING GENIE: GENIE combines the control-enhancing linear spring rate of a coil spring through the “bump zone” with the progressive spring rate of an air spring at the end of the stroke to avoid bottom-outs. Truly, it's the best of both worlds – coil and air – with extra tunability. Say goodbye to compromises and hello to the future of riding.

WHAT BUMP?: With 16.3% better bump force management than a traditional air-sprung shock, GENIE makes the Stumpy 15 ride like a bike with more travel. For example, the Stumpjumper 15 (with 145 mm rear wheel travel) and our Enduro (170 mm travel) both use 101 mm of travel to absorb a 1080 N bump force.

TRACTION GALORE: Extensive field testing proves that Stumpjumper 15 with GENIE delivers 57% better traction than a standard air-sprung shock because GENIE technology gives you supple, coil-like performance, which keeps the wheel in contact with the ground a greater percent of the time than a typical air spring would.

BYE, BYE, BOTTOM-OUTS: 39% fewer bottom-outs than a standard air spring. During big hit events, you benefit from the rising rate in the last 30% of the GENIE stroke. Because of this two-stage, pronounced rising rate, GENIE reduces the frequency and severity of bottom-outs.

HONED GEOMETRY: This bike’s geometry delivers big bike capability when you need it, a nimble feel in tight sections, and lively, efficient climbing manners. The generous cockpit centers you on the bike, optimizing traction and corner control. The low bottom bracket, slack head tube angle, and optimized fork offset keep things stable in the rough.

Highly adjustable 2-position open and firm mode with the 3-position open mode compression adjuster.
• Supportive and tuneable FOX FLOAT 36 Performance Elite fork with GRIP X2 damper
• Strong and trusted Roval Traverse wheels, DT Swiss 370 hub

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.

Just when we thought we couldn’t possibly outdo ourselves, we did. The S-Works Stumpjumper LTD will take your trail riding to a whole new level with a mixed wheel setup, SRAM XX1 Eagle AXS wireless electronic groupset, FOX FLOAT 36 Factory fork and FOX FLOAT X Factory shock, and SRAM Code RSC 4-piston brakes.

• 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.
