Specialized Stumpjumper 15 EVO Pro: Ultimate Trail Performance With GENIE Suspension

The Specialized Stumpjumper 15 EVO Pro is built for riders who want zero compromises on the trail. It delivers big-bike confidence when things get rough, playful responsiveness when the trail tightens up, and elite-level efficiency when it’s time to climb. At the heart of this bike is Specialized’s groundbreaking GENIE Shock Technology, paired with a lightweight FACT 11m carbon chassis and top-tier components. The result is a trail bike that adapts to you, your terrain, and your riding style better than anything before it.

Key Benefits for Riders

GENIE Shock Technology: Coil Feel With Air Spring Versatility

The biggest breakthrough on the Stumpjumper 15 EVO Pro is GENIE Shock Technology. This patent-pending system blends the supple, linear feel of a coil spring through small and mid-size bumps with the progressive bottom-out resistance of an air spring at the end of the stroke. The payoff is massive: better traction, fewer harsh bottom-outs, and a playful, supportive platform that makes the bike feel both bottomless and lively. Compared to a traditional air shock, GENIE delivers dramatically improved bump absorption and keeps the rear wheel glued to the ground.

FACT 11m Carbon Chassis With Trail-Tuned Geometry

The FACT 11m carbon frame balances stiffness, strength, and weight for aggressive trail riding. Its modern trail geometry puts you centered in the bike for maximum traction and corner control, while the low bottom bracket and slack head angle provide confidence in steep and rough terrain. Despite its big-bike capability, the Stumpjumper 15 EVO Pro remains efficient and responsive on climbs, making it a true all-day trail weapon.

Unmatched Personalization and Adjustability

This is one of the most adjustable trail bikes ever built. The Stumpjumper 15 EVO Pro offers six-way geometry adjustment, allowing you to fine-tune head angle and bottom bracket height to match your terrain and riding style. It also supports both full 29” and mixed-wheel setups, letting you choose maximum rollover speed or a more playful, agile rear end without compromising geometry. This level of personalization means the bike can evolve with you as your skills and preferences grow.

Elite FOX Factory Suspension for Total Control

Up front, the FOX FLOAT 36 Factory fork with GRIP X2 damper delivers exceptional stiffness, sensitivity, and tuning range. Out back, the FOX FLOAT X Factory GENIE shock is Ride Dynamics tuned specifically for this frame, offering a highly adjustable platform that excels on both technical climbs and aggressive descents. Together, this suspension package provides outstanding traction, stability, and confidence at speed.

SRAM X0 Eagle AXS Transmission and Maven Braking

The SRAM X0 Eagle AXS Transmission delivers crisp, precise wireless shifting under load, making gear changes effortless even on steep, technical climbs. Braking is handled by SRAM Maven Silver 4-piston brakes, offering powerful, consistent stopping power with excellent modulation, giving you full control when charging hard into steep descents.

Lightweight Carbon Wheels and Premium Touch Points

The bike rolls on Roval Traverse SL II carbon wheels with Industry Nine hubs, combining low rotational weight with durability for aggressive trail riding. A Bike Yoke Revive Max dropper post provides reliable, ultra-smooth saddle height adjustment, while premium cockpit components ensure precise handling and long-ride comfort.

Why Choose the Specialized Stumpjumper 15 EVO Pro?

If you want a trail bike that erases compromises, adapts to your riding style, and delivers elite-level performance everywhere on the mountain, the Specialized Stumpjumper 15 EVO Pro stands alone. With GENIE suspension, unmatched adjustability, and top-tier components throughout, it’s a bike designed to ride harder, faster, and more confidently than ever before.
