Stumpjumper 15 Comp

The Stumpjumper 15 is here to eliminate every compromise in the trail game. It devours bumps like a big bike, combines short-travel agility with killer playfulness and efficiency, and offers more personalisation than ever before. This bike is all about making the ride perfect for the only rider who really matters: you.

BREAKTHROUGH CAPABILITY:

GENIE Shock Technology brings together the best of both worlds, offering the pop and playfulness of a coil spring with the plush bottomless feel of a downhill bike.

ULTIMATE CONTROL:

With measurably better traction than the “Bike of the Year” Stumpjumper EVO, the Stumpjumper 15 provides unparalleled control and stability, no matter what the trail throws at you.

UNMATCHED PERSONALISATION:

Custom-tailor your ride with six-way geometry adjustments, your choice of mixed wheels or full 29” setup, and a tunable spring curve. The Stumpjumper 15 adapts to your riding style and terrain like never before.

GENIE—THE MAGIC CARPET RIDE:

The GENIE is the game-changing technology at the heart of the Stumpjumper 15. This patent-pending air spring system combines the best traits of a coil spring and air spring, giving you a plush, controlled ride with extra tunability. It’s everything a trail rider could wish for.

ILLUMINATING GENIE:

GENIE combines a linear spring rate through the "bump zone" for enhanced control, with a progressive rate at the end of the stroke to prevent bottom-outs. It’s the perfect blend of coil-like feel and air spring efficiency—designed to make your ride smoother and more capable than ever.

WHAT BUMP?:

GENIE manages bump forces 16.3% better than a traditional air shock, giving the Stumpjumper 15 the performance feel of a bike with more travel. For example, the Stumpjumper 15 (145mm rear travel) absorbs a 1080 N bump with just 101mm of travel, matching the performance of our Enduro bike (170mm travel).

TRACTION GALORE:

Extensive testing shows that the Stumpjumper 15 with GENIE provides 57% better traction than a standard air shock. The supple, coil-like feel keeps the wheel in contact with the ground longer, improving grip and control through technical sections.

BYE-BYE, BOTTOM-OUTS:

Thanks to its two-stage rising rate, GENIE delivers 39% fewer bottom-outs than a standard air spring. During big hits, the rising rate in the last 30% of the shock’s stroke cushions the impact, reducing both frequency and severity of bottom-outs.

HONED GEOMETRY:

The Stumpjumper 15 features geometry that blends big bike stability with a nimble feel in tight sections and efficient climbing performance. The low bottom bracket, slack head tube angle, and optimised fork offset keep you stable through rough terrain, while a spacious cockpit puts you in the sweet spot for maximum traction and cornering control.

RIDE YOUR WAY:

Stumpjumper 15 is the most customisable trail bike on the market. With six distinct geometry settings, you can fine-tune the bike’s performance for any style or terrain. Adjust the head angle and bottom bracket height to enhance stability, agility, or clearance depending on what you’re riding.

WHEEL CHOICE:

Choose between full 29” wheels for speed and stability or a mixed 27.5” rear, 29” front setup for added playfulness and responsiveness. With our aftermarket shock links, your geometry remains unaffected, no matter your wheel choice.

CARRY IT ALL:

The SWAT 4.0 system takes downtube storage to the next level. With weather-resistant, flush-mounted compartments, you can carry all your gear without compromising the bike’s clean lines and performance.

MORE RELENTLESS THAN YOU:

Built to handle years of hard riding, the Stumpjumper 15 is supported by the best policies in the industry. Our lifetime replacement of suspension pivot bearings for the original owner is just one example of how we’ve got your back on the trail.
