Specialized Stumpjumper 15 Comp Alloy Trail Mountain Bike
The Specialized Stumpjumper 15 Comp Alloy is built to tackle any trail with unmatched performance and personalization. Designed with breakthrough GENIE Shock Technology, this bike provides the ultimate combination of traction, control, and efficiency, making it the perfect choice for riders seeking a versatile trail bike. Whether you're navigating tight switchbacks or charging down rough descents, the Stumpjumper 15 Comp delivers a dynamic and responsive ride that can be finely tuned to suit your style.
Key Benefits for Riders
GENIE Shock Technology for a Tailored Ride
The GENIE Shock Technology at the core of the Stumpjumper 15 Comp brings a unique combination of coil-like traction and air spring performance. With better bottom-out prevention than traditional air springs, GENIE gives you a smoother ride, absorbing impacts like a longer-travel bike while maintaining efficient pedaling performance. The two-position damper (open and firm) allows you to easily adjust your ride's responsiveness for different trail conditions, giving you complete control over the bike's performance.
Enhanced Traction and Control
With the GENIE air spring, you’ll experience better grip and traction on rough trails, ensuring that the wheels stay connected to the ground longer than with a standard air-sprung shock. This results in superior stability and more control during technical descents, increasing confidence when tackling tough sections of trail.
Responsive Geometry and Adjustability
The Stumpjumper 15 Comp Alloy features six distinct geometry settings, allowing you to fine-tune your bike for stability or responsiveness. Adjustments to the head angle and bottom bracket height enable riders to customize their setup for specific terrain, whether you prefer a more stable, aggressive feel or a nimble, playful ride through tight turns.
Robust Build with Performance Components
The M5 alloy frame of the Stumpjumper 15 Comp provides a durable, lightweight chassis, paired with the SWAT™ Door integration for easy storage of tools and gear. The FOX FLOAT 36 Rhythm fork with GRIP damper offers smooth travel up to 150mm, while the FOX FLOAT Performance shock with GENIE tuning ensures excellent bump absorption and support on rough trails. A Shimano SLX 12-speed drivetrain and TRP Trail EVO 4-piston brakes ensure precise shifting and reliable stopping power when you need it most.
Durability and Comfort for Every Ride
The X-Fusion Manic dropper post offers infinite adjustment, allowing you to easily dial in your saddle height for any situation. Whether you're climbing or descending, the dropper post ensures a comfortable and efficient ride. The bike is also backed by lifetime replacement of suspension pivot bearings to the original owner, giving you peace of mind for years of hard riding.
