SPECIALIZED S-WORKS STUMPJUMPER BICYCLE 15

The Stumpjumper 15 with GENIE gives me the advantages of a bike with generous travel, and also those of a bike with shorter travel, all in one. - Allan Cooke.

The Stumpjumper 15 removes every compromise in the trail world. Devouring big obstacles like a bike with generous travel? Done. Control, playfulness and efficiency like an XC bike? Done. Wide customization options to make it perfect for the one rider who really matters: you? Done, done, done.

REVOLUTIONARY CAPACITY: GENIE combines a lively, playful ride with a DH-like travel feel.

SUPERIOR CONTROL: Tangibly better traction than the “Bike of the Year,” the Stumpjumper EVO.

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

GENIE—The flying carpet: The biggest innovation on the Stumpjumper 15 is GENIE. This air-sprung, patent-pending technology we invented fulfills three wishes of every cyclist: the feel and control of a coil spring, better bottom-out resistance than a standard air spring, and an adjustable platform for a playful feel.

THE 'GENIUS': GENIE combines the linear stiffness of a coil spring that improves control through the “hit zone” with the progressive curve of air spring at the end of travel to prevent bottoming out. Truly, it’s the best of both worlds—coil and air—with extra adjustment range. Say goodbye to compromises and welcome the future of suspension.

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

GO-ANYWHERE TRACTION: Field testing shows that the Stumpjumper 15 with GENIE provides 57% better traction than a standard air-sprung shock because GENIE offers flexible performance similar to a coil spring, keeping the wheel in contact with the ground longer than a typical air spring.

GOODBYE BOTTOM OUT: 39% fewer bottom-out events than a standard air spring. With big impacts, 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 gravity of bottom-out events.

PERFECT GEOMETRY: The geometry of this bike offers great clearance when needed, agility on tight sections, and climbing efficiency. The large cockpit centers you on the bike, optimizing traction and cornering control. The low bottom bracket, relaxed head angle, and optimized fork offset promote stability even on technical terrain.

YOUR WAY: The Stumpjumper 15 perfectly 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. The head angle and bottom bracket height can be precisely adjusted to ensure stability or liveliness.

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

ALL THE NECESSARY CARRYING: The SWAT 4.0 storage compartment on the Stumpjumper 15 increases space in the down tube, an innovation we pioneered.
