Specialized Stumpjumper 15 S-Works: The Ultimate Trail Bike
The Stumpjumper 15 S-Works with GENIE Shock Technology combines the best of both worlds — the big travel bike benefits and the short travel bike agility, all in one package. Whether you're charging through rough trails or cruising on smooth singletrack, the Stumpjumper 15 is engineered to deliver an unmatched, customizable trail experience. With its advanced shock tech and geometry, this bike offers top-tier performance in every condition.
Key Benefits for Riders
GENIE Shock Technology: The Magic Carpet Ride
The GENIE Shock Technology is the standout feature of the Stumpjumper 15. It combines the poppy, playful ride of a short-travel bike with the bottomless DH feel of a big travel bike. By using patent-pending air spring technology, GENIE provides the feel and control of a coil spring while offering better bottom-out prevention than traditional air springs. This innovative shock design creates a smooth ride that handles bumps with ease and adds extra tunability for a personalized feel.
Unmatched Traction and Control
Thanks to GENIE’s coil-like performance, the Stumpjumper 15 delivers an impressive 57% better traction than a standard air-sprung shock. The shock keeps the wheel in contact with the ground longer, improving your control on technical trails and offering a more responsive ride. The bike’s 16.3% better bump force management ensures that even with 145mm of rear wheel travel, the bike can absorb large hits without compromising the ride quality, feeling like a bike with even more travel.
Enhanced Bottom-Out Prevention
The Stumpjumper 15 is designed to minimize bottom-outs, with a 39% reduction compared to a traditional air-sprung shock. Thanks to GENIE’s two-stage, rising rate at the end of the stroke, the bike reduces both the frequency and severity of bottom-outs, allowing you to ride harder and push the bike further without compromising comfort.
Honed Geometry for Perfect Handling
The Stumpjumper 15’s geometry is designed to provide a stable, nimble ride. With a low bottom bracket, slack head tube angle, and optimized fork offset, this bike remains stable in rough terrain while still being agile enough for tight corners. The generous cockpit ensures that you stay centered on the bike, optimizing traction and corner control. Whether you’re climbing, descending, or riding through technical sections, the Stumpjumper 15 handles it all with ease.
Personalize Your Ride with Geometry Adjustments
With six distinct geometry settings, the Stumpjumper 15 allows you to fine-tune the bike’s performance to suit your style and terrain. Adjust the head angle and bottom bracket height for stability, or clearance, depending on the trail conditions. This level of personalization makes it the most adaptable trail bike on the market.
Wheel Choice Flexibility
Thanks to aftermarket shock links, you can choose between 29-inch wheels for maximum control or opt for a mixed-wheel setup with a 27.5-inch rear wheel for a more playful ride. Regardless of your wheel choice, the bike’s geometry remains unaffected, giving you flexibility in how you want to ride.
Carry More with SWAT 4.0
The SWAT 4.0 system on the Stumpjumper 15 offers the best downtube storage available. This innovation allows you to carry your gear securely, keeping your bike’s sleek profile while offering easy access to your essentials. Whether you're heading out for a full day of riding or a quick adventure, SWAT 4.0 lets you carry it all with ease.
Why Choose the Specialized Stumpjumper 15 S-Works?
The Specialized Stumpjumper 15 S-Works is the ultimate trail bike, blending the best features of big and short travel bikes with cutting-edge technology and customizable options. With GENIE shock technology, exceptional traction, and unmatched adjustability, this bike is designed to handle any trail and rider preference.
