Specialized Stumpjumper 15 EXPERT GUN/WHTMTN S3

The Stumpjumper 15 is designed to eliminate every compromise in the trail bike world. It devours bumps like a big bike, combines short-travel precision with the perfect balance of playfulness and efficiency, and offers a level of personalisation that makes it your bike, no one else’s.

BREAKTHROUGH CAPABILITY:

GENIE Shock Technology is the heart of the Stumpjumper 15, blending the poppy, playful nature of a coil spring with the bottomless feel of a DH bike, delivering a ride that’s smooth and controlled over every type of terrain.

ULTIMATE CONTROL:

With superior traction compared to the Stumpjumper EVO (our "Bike of the Year"), the Stumpjumper 15 is designed to offer better control, stability, and confidence in all conditions.

UNMATCHED PERSONALISATION:

Tailor your ride with six-way geometry adjustment, choose between mixed wheels or full 29”, and fine-tune your ride with a tunable spring curve to fit any terrain or riding style.

GENIE—YOUR MAGIC CARPET RIDE:

The GENIE air spring system is the Stumpjumper 15’s biggest innovation. This patent-pending technology gives you the feel and control of a coil spring, with better bottom-out prevention than a standard air spring, and a tunable platform that enhances playfulness. It’s the ultimate shock innovation, giving you the best of both coil and air spring worlds, with full adjustability.

WHAT BUMP?

With 16.3% better bump force management than traditional air shocks, GENIE makes the Stumpjumper 15 feel like it has more travel. For example, while the Stumpjumper 15 has 145mm of rear travel, it absorbs bumps with a level of control normally reserved for bikes with 170mm of travel.

TRACTION GALORE:

GENIE provides 57% more traction than a standard air shock. Its supple, coil-like performance keeps the wheels in constant contact with the ground, improving grip and stability—especially on tricky, technical terrain.

BYE, BYE, BOTTOM-OUTS:

Thanks to GENIE’s rising rate, you’ll experience 39% fewer bottom-outs compared to a standard air spring. The last 30% of the stroke features a pronounced rising rate, helping to cushion big hits and reduce both the frequency and severity of bottom-outs.

HONED GEOMETRY:

The Stumpjumper 15 geometry is designed to give you big bike stability when you need it, and a nimble, responsive feel in tighter sections. The low bottom bracket, slack head tube angle, and optimised fork offset combine to keep you stable on rough trails while maintaining agile handling.

RIDE YOUR WAY:

The Stumpjumper 15 is the most adjustable trail bike out there, with six geometry settings that let you dial in the perfect balance between stability, clearance, and agility for any style of riding or terrain.

WHEEL CHOICE:

Customise your ride with either full 29” wheels for smooth, fast rolling or a mixed wheel setup (27.5” rear, 29” front) for a more playful, responsive feel. And with aftermarket shock links, the bike’s geometry remains unchanged no matter which wheel choice you make.

CARRY IT ALL:

With the SWAT 4.0 system, Stumpjumper 15 sets the standard for downtube storage. It’s the smoothest, most weather-resistant, and flush-mounted system we’ve ever designed—perfect for carrying gear without compromising performance.

MORE RELENTLESS THAN YOU:

Engineered to last, the Stumpjumper 15 comes with lifetime replacement of suspension pivot bearings for the original owner. Designed to take on years of rugged trail riding, this bike is built to endure.
