The Stumpjumper 15 with GENIE gives me the benefits of a long-travel bike, and the benefits of a short-travel bike, all rolled into one. - Allan Cooke.

The Stumpjumper 15 takes the compromise out of the trail. Gobble up big obstacles like a full-travel bike? Check. Control, playfulness, and efficiency like an XC bike? Check. Massive customization to make it perfect for the only rider that really matters: you? Check, check, check.

GROUNDBREAKING CAPABILITY: GENIE technology pairs snappy, playful handling with a DH-travel feel.

SUPREME CONTROL: Traction that's noticeably better than the Bike of the Year, the Stumpjumper EVO.

CUSTOMIZATION: Six geometry settings, mullet or 29er build, adjustable compression curve, and more.

GENIE—The Magic Carpet: The biggest innovation on the Stumpjumper 15 is GENIE. Our patent-pending air spring technology satisfies the three things every rider wants: the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and an adjustable platform for a playful feel.

THE ‘GENIE’: GENIE combines the linear stiffness of a coil spring for improved control through the “bump zone” with the progressive curve of an air spring at the end of the stroke to prevent bottom-outs. Truly, it’s the best of both worlds – coil and air – with extra adjustability. Say goodbye to compromise and hello to the future of suspension.

WHAT BUMP?: With 16.3% better bump force management than a traditional air shock, GENIE makes sure you get the most out of your ride. that the Stumpy 15 rides like a bike with more travel. For example, the Stumpjumper 15 (with 145mm of rear travel) and our Enduro (170mm of travel) both use 101mm of travel to absorb 2,500 lb. of impact force.

TRACTION TO THE MAX: Extensive field testing shows that the Stumpjumper 15 with GENIE provides 57% better traction than a standard air shock because GENIE technology offers supple, coil-like performance that keeps the wheel on the ground for a greater percentage of the time than a typical air shock.

GOODBYE BOTTOM OUTS: 39% fewer bottom-outs than a standard air spring. On big hits, you'll benefit from the progressive curve in the last 30% of GENIE's travel. Thanks to its two-stage behavior, GENIE reduces the frequency and severity of bottom-outs.

REFINED GEOMETRY: This bike's geometry offers big capability when you need it, agility in tight sections, and efficiency on climbs. The wide cockpit centers you on the bike, maximizing traction and control through corners. A low bottom bracket, slack head angle, and optimized fork offset help keep you stable on technical terrain.

YOUR WAY: The Stumpjumper 15 features seamless geometry adjustment, making it our most customizable trail bike ever. Six distinct geometry settings let you fine-tune performance for any style of riding and any terrain. The head angle and bottom bracket height can be fine-tuned for stability, control, and stability. or light.

WHEEL CHOICE: Our aftermarket links give you the choice of big wheels front and rear, or you can run a 27.5" rear wheel for a more responsive, playful ride. Whatever you choose, the geometry stays the same.

CARRY THE GEAR: The SWAT 4.0 compartment on the Stumpjumper 15 increases down tube clearance, an innovation we pioneered.
