SPECIALIZED STUMPJUMPER 15 EXPERT BIKE

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

The Stumpjumper 15 eliminates any compromise in the trail world. Tackle big obstacles like a bike with generous travel? Done. Control, playfulness, and efficiency like an XC bike? Done. Extensive customization to make it perfect for the only biker that really matters: you? Done, done, done.

REVOLUTIONARY CAPABILITY: The GENIE technology combines a snappy, playful ride with a downhill travel sensation.

SUPREME 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 patent-pending air spring technology we invented fulfills every cyclist'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 'GENIUS': GENIE combines the linear stiffness of the coil spring that enhances control through the "bump zone" with the progressive curve of the air spring at the end of the travel to prevent bottom-out. Truly, it's the best of both worlds – coil and air – with extra adjustability. Say goodbye to compromises and welcome the future of suspension.

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

TRACTION GALORE: Extensive field testing shows that Stumpjumper 15 with GENIE provides 57% better traction than a standard air shock because the GENIE technology offers flexible, coil-like performance, keeping the wheel in contact with the ground for a greater percentage of time compared to a typical air spring.

GOODBYE BOTTOM OUT: 39% fewer bottom-out events compared to a standard air spring. In the case of big impacts, you’ll benefit from the progressive curve in the last 30% of the GENIE travel. Thanks to the two-phase behavior, GENIE reduces the frequency and severity of bottom-out events.

PERFECTED GEOMETRY: The bike's geometry offers great capability when needed, agility in tight sections, and efficiency on climbs. The spacious cockpit centers you on the bike, optimizing traction and cornering control. The low bottom bracket, slack head angle, and optimized fork offset contribute to 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 the performance for any style and terrain. The head angle and bottom bracket height can be precisely adjusted to ensure stability or clearance.

WHEEL CHOICE: With our aftermarket links, you can choose 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 remains unaffected.

BRING EVERYTHING YOU NEED: The SWAT 4.0 compartment on the Stumpjumper 15 increases space in the downtube.
