SPECIALIZED STUMPJUMPER 15 COMP BIKE

Officially the Best Trail Bike of the Year
The Stumpjumper 15 was named “Best in Test” by Enduro Mountainbike Magazine, standing out among the most advanced trail bikes of the year. Thanks to its GENIE suspension and its handling and versatility, the Stumpjumper 15 is truly the bike that dominates every trail.

The Stumpjumper 15 with GENIE gives me the advantages of a long-travel bike, and also those of a short-travel bike, all at once. - Allan Cooke.

The Stumpjumper 15 eliminates any compromise in the trail world. Devouring big obstacles like a long-travel bike? Done. Control, playfulness, and efficiency like an XC bike? Done. Extensive customization options to make it perfect for the only rider who truly matters: you? Done, done, done.

REVOLUTIONARY CAPABILITY: GENIE technology combines snappy, playful handling with a DH-like travel feel.

SUPREME CONTROL: Tangibly better traction than the "Bike of the Year," the Stumpjumper EVO.

GENIE—The Magic Carpet: The biggest innovation on the Stumpjumper 15 is GENIE. This patent-pending air spring technology, invented by us, grants every rider's three wishes: 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 that improves control through the "bump zone" with the progressive air spring curve 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 welcome the future of suspension.

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

TRACTION GALORE: Extensive field tests show that the Stumpjumper 15 with GENIE provides 57% better traction than a standard air spring shock because GENIE technology delivers supple, coil-like performance that keeps the wheel in contact with the ground for a greater percentage of the time than a typical air spring.

SAY GOODBYE TO BOTTOM-OUT: 39% fewer bottom-out events than a standard air spring. On big hits, you’ll benefit from the progressive curve in the last 30% of GENIE’s stroke. Thanks to its two-stage behavior, GENIE reduces the frequency and severity of bottom-out events.

PERFECTED GEOMETRY: This bike's geometry offers great capability when needed, agility in tight sections, and climbing efficiency. The wide cockpit centers you on the bike, optimizing traction and control in corners. The low bottom bracket, relaxed head angle, and optimized fork offset promote stability even on technical terrain.

YOUR WAY: The Stumpjumper 15 seamlessly integrates geometry adjustment, making it the most customizable trail bike ever. Six distinct geometry settings allow you to fine-tune performance for any style and terrain. Head angle and bottom bracket height can be precisely adjusted to ensure stability or clearance.

WHEEL CHOICE: With our aftermarket links, you can choose between large wheels both front and rear, or you can use a 27.5" rear wheel for a more responsive and playful ride. Whatever you choose, the geometry is unaffected.

CARRY EVERYTHING YOU NEED: The SWAT 4.0 compartment on the Stumpjumper 15 increases downtube storage space, an innovation we pioneered.
