S-Works Stumpjumper 15

The Stumpjumper 15 is here to crush every compromise in the trail bike world. Whether you're carving through technical rock gardens, conquering climbs, or shredding descents, this bike delivers it all. It combines the plush, big-bike feel with the nimble playfulness and efficiency of short-travel performance. And with a level of personalisation that ensures it fits you perfectly, the Stumpjumper 15 is all about taking your ride to the next level.

BREAKTHROUGH CAPABILITY:

The GENIE Shock Technology on the Stumpjumper 15 fuses the pop and playfulness of a short-travel bike with the bottomless feel of a long-travel downhill machine.

ULTIMATE CONTROL:

With GENIE technology, the Stumpjumper 15 provides measurably better traction than the acclaimed Stumpjumper EVO, giving you more grip and confidence than ever before.

UNMATCHED PERSONALISATION:

Fine-tune your ride to perfection with six-way adjustable geometry, mixed-wheel or 29” setups, tunable spring curves, and more. It's everything you need to dial in your ride, your way.

GENIE—The Magic Carpet Ride:

The biggest leap in the Stumpjumper 15 is GENIE, our groundbreaking, patent-pending air spring technology. GENIE delivers the feel and control of a coil spring, prevents bottom-outs like a top-tier air spring, and provides a tunable “platform” for a playful ride that adapts to you.

ILLUMINATING GENIE:

GENIE combines the best of both coil and air spring worlds. It offers the linear spring rate of a coil spring through the “bump zone” for more control, while the progressive air spring at the end of the stroke helps prevent bottom-outs. The result? A smooth, controlled ride with more tunability and less compromise.

WHAT BUMP?:

GENIE delivers 16.3% better bump force management than a traditional air shock, making the Stumpjumper 15 feel like a bike with more travel. It absorbs high-impact forces—like a 1080 N bump—with the same efficiency as our Enduro (with 170mm of rear travel).

TRACTION GALORE:

Field testing shows GENIE provides 57% better traction than a standard air shock. The supple, coil-like feel keeps the wheel in constant contact with the ground, improving traction and control on even the roughest trails.

BYE, BYE, BOTTOM-OUTS:

With 39% fewer bottom-outs than a standard air spring, GENIE uses a rising rate in the last 30% of the stroke to significantly reduce bottom-out frequency and severity. Say goodbye to harsh hits and hello to smooth, controlled descents.

HONED GEOMETRY:

The Stumpjumper 15’s geometry strikes the perfect balance between big-bike capability and nimble handling. The generous cockpit centres you on the bike, optimising traction and cornering. A low bottom bracket, slack head angle, and optimised fork offset provide stability and control, so you can attack any trail with confidence.

RIDE YOUR WAY:

With six geometry settings, the Stumpjumper 15 lets you easily fine-tune your bike for any terrain, any riding style. Adjust the head angle and bottom bracket height to dial in your stability or clearance—your ride, your rules.

WHEEL CHOICE:

Whether you choose a 29” front and 29” rear setup or opt for a more playful 27.5” rear wheel, the Stumpjumper 15 gives you the flexibility to customise the ride you want without affecting geometry.

CARRY IT ALL:

The SWAT 4.0 system on the Stumpjumper 15 takes down-tube storage to the next level. With the smoothest operation, weather-resistant build, and flush-mount design, it’s the ultimate solution for carrying tools, food, and essentials on the trail.
