Stumpjumper 15 has been named “Best in Test” by Enduro Magazine, standing out among the most advanced trail bikes of the year. With its GENIE suspension, balanced handling, and all-terrain versatility, it truly is One Bike to Rule All Trails.
This game-changing, patent-pending air spring technology that we invented grants every trail rider three wishes: feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable “platform" for a playful feel.
Check out how 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 reduce bottom-outs. It's the best of both worlds – coil and air – with extra tuneability. Say goodbye to compromises and hello to the future of riding.
Stumpjumper 15 boasts the planet's most capable trailgeometry. With six-way adjustability, tailor your ride toperfectly match your style and terrain. Explore ourinteractive Geo Finder to pinpoint your ideal setting
GENIE shock technology gives the Stumpy 15 16.3% better bump performance than ‘Bike of the Year’ Stumpjumper EVO. It literally uses more travel for the same size bump, thanks to its flatter spring curve in the first 70% of travel.
GENIE delivers 57% less traction loss time 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.
Send it with confidence knowing that in field testing GENIE eliminated 39% of severe bottom out events compared to a standard FOX Float air spring.
Many (dirty) hands, one (awesome) bike. Over 50 R&D teammates, each and every one a trail rider, worked for more than three years to make Stumpjumper 15 One Bike to Rule All Trails.

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.
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 height can be fine-tuned for stability or clearance.
WHEEL CHOICE: With our aftermarket 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 of suspension pivot bearings to the original owner is just one way we've got you covered.

the rig is as advertised. got rid of my stumpjumper evo sworks and tall boy to buy this bike last september. no test ride, just a belief in the lofty promises of the specialized copywriters. first trail was chimney gulch in golden, co. trimmed 3-4 minutes off of the 3. 5-mile, 1. 8k climb. ripped down just like the evo. this bike is spectacular. the balance and handling are unlike anything i’ve ridden. uphill tech? check. speed? check. dh? oh, yeah. had one wish of the genie… give me the best bike on the market. she delivered.
★★★★★
I've had this for 6 months and this is the best bike I've owned, for sure. The Genie shock works great as shipped, and the air spring is easily tuned to be more or less progressive. I've set this bike up both lighter/more pedally and completely downhill focused and was surprised at how versatile it is. Whether you are set-it-and-forget-it or into tinkering, this bike just works.
★★★★★
I have a quiver, and this is my "big bike. " It can ride off the summit of the local ski hill, crush New England chunk, and pedal back up smoothly and comfortably. This bike has such a wide range, and its build quality is superb- so refined. I love it!
