Mountain bike Specialized STUMPJUMPER 15 EXPERT

The Specialized Stumpjumper 15 Expert is a high-performance trail bike, engineered to eliminate compromises and deliver breakthrough capability, control, and customization. Featuring GENIE shock technology, six-way geometry adjustability, and top-tier components, this bike is built to dominate technical terrain, flowy descents, and steep climbs alike.
Breakthrough GENIE Shock Technology
The patent-pending GENIE air spring system delivers the best of both coil and air suspension—supple, linear support through rough terrain with progressive bottom-out resistance. Compared to traditional air shocks, GENIE offers:
✅ 16.3% better bump absorption, making it ride like a longer-travel bike.
✅ 57% better traction, keeping the rear wheel in contact with the ground for superior control.
✅ 39% fewer bottom-outs, using a progressive two-stage compression curve.

Tuned FOX Suspension & Precision Handling
The FOX FLOAT 36 Performance Elite fork with a GRIP X2 damper provides smooth, controlled front-end performance, while the FOX FLOAT Performance Elite rear shock is Ride Dynamics tuned for enhanced traction, stability, and support.

Customizable Geometry for Every Rider
With six geometry settings, the Stumpjumper 15 Expert allows you to adjust head tube angle and bottom bracket height, fine-tuning stability, playfulness, and efficiency. Choose between full 29” wheels or a mullet setup (27.5” rear) with an aftermarket shock link to match your riding style.

Premium Components for Maximum Performance
The SRAM GX Eagle T-Type AXS drivetrain ensures wireless shifting precision, while SRAM Maven Bronze 4-piston brakes deliver consistent stopping power. Roval Traverse wheels with DT Swiss 370 hubs provide durability and responsiveness on aggressive terrain.
