Stumpjumper 15 EVO Expert Sram AXS 2026

The Stumpjumper 15 with GENIE gives me the advantages of a bike with generous travel, and also those of a bike with reduced travel, all together. - Allan Cooke. The Stumpjumper 15 eliminates every compromise in the trail world. Devour 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 only rider that really matters: you? Done, done, done.

REVOLUTIONARY CAPACITY: GENIE technology combines a snappy and playful ride with the feel of DH excursions.

CONTROLLO SUPREMO: Tangibly better traction compared to 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 spring technology, pending patent and invented by us, fulfills the three wishes of every cyclist: the feel and control of a coil spring, better bottom-out prevention compared to a standard air spring, and an adjustable platform for a playful feel.

THE 'GENIUS': GENIE combines the linear stiffness of the coil spring, which improves control through the "bump zone," with the progressive curve of the air spring at the end of the stroke to avoid bottoming out. Truly, it's the best of both worlds – coil and air – with extra adjustment options. Say goodbye to compromises and welcome the future of suspension.

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

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

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

GEOMETRY PERFECTED: the geometry of this bike offers great capability when needed, agility in tight sections, and efficiency on climbs. The wide 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.

A MODO TUO: 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 clearance.

WHEEL CHOICE: With our aftermarket links, you can choose between large wheels on both the 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 not affected.

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