Specialized Stumpjumper 15 Expert Trail Mountain Bike
The Specialized Stumpjumper 15 Expert is built to take on the toughest trails with a perfect blend of performance, control, and personalization. With cutting-edge GENIE Shock Technology and advanced geometry, this bike is designed to obliterate any compromises in the trail game. Whether you’re powering through bumps, enjoying a playful ride, or adjusting your geometry for maximum performance, the Stumpjumper 15 Expert is ready for any challenge.
Key Benefits for Riders
GENIE Shock Technology for Unmatched Ride Quality
The GENIE Shock Technology revolutionizes the ride, combining the best features of both coil and air springs. With a tunable spring curve and improved bottom-out prevention, it gives you the control and comfort of a coil spring, along with the progression and adjustability of an air spring. This combination results in a shock that offers both playfulness and bottomless feel, allowing you to tackle any terrain with ease.
Improved Traction and Control
The Stumpjumper 15 delivers 57% better traction than traditional air-sprung shocks, thanks to its GENIE technology. This provides a supple, coil-like performance, ensuring your wheels stay in contact with the ground for maximum grip. Whether you're on steep climbs or tricky descents, you'll experience improved control and stability.
Enhanced Geometry for Stability and Playfulness
With six adjustable geometry settings, the Stumpjumper 15 lets you fine-tune your ride for any terrain. Whether you need a more stable setup for rough sections or a more agile feel for tight turns, the bike's low bottom bracket and slack head tube angle provide excellent control and confidence. The geometry is designed to offer big-bike capability without sacrificing maneuverability or climbing efficiency.
Durable and Customizable Build
The FACT 11m carbon chassis provides an excellent balance of stiffness and compliance, delivering a responsive ride that doesn’t sacrifice comfort. The bike’s frame integrates the SWAT™ Door for convenient downtube storage, and the PNW Loam dropper post offers adjustable travel for the perfect seat height at any point during your ride.
Built for the Long Haul
Engineered for endurance, the Stumpjumper 15 comes with lifetime suspension pivot bearing replacement for the original owner. This ensures that you can ride hard without worrying about wear and tear, and with the support of Specialized’s outstanding customer service, you can rely on your bike to handle whatever the trails throw at it.
Ultimate Performance with SRAM and FOX Components
The Stumpjumper 15 is equipped with SRAM GX Eagle drivetrain and SRAM Maven Bronze 4-piston brakes, offering precise shifting and powerful stopping power. The FOX FLOAT Performance Elite shock and FOX FLOAT 36 Performance Elite fork are tuned for optimal performance, providing 145mm of rear travel and 150mm of front travel to tackle rough terrain and big hits with ease.
Why Choose the Specialized Stumpjumper 15 Expert?
