Specialized Stumpjumper 15 Alloy Mountain Bike: Ultimate Trail Performance

The Specialized Stumpjumper 15 Alloy Mountain Bike is engineered to dominate the trail, offering the perfect blend of big-bike bump absorption, short-travel control, and efficient performance. Personalisation is key, and this bike is designed to adapt to your riding style, making it perfect for the most important rider, you.

Kinematics Perfected for Efficiency and Control. The Stumpjumper 15 Alloy excels in balancing pedaling efficiency and bump force management. With anti-squat tuned between the Stumpjumper and Stumpjumper EVO, this trail bike offers exceptional pedaling characteristics, allowing you to conquer climbs and descents with ease.

Optimised Geometry for Any Trail. The geometry of the Stumpjumper 15 Alloy delivers the best of both worlds, big bike stability for rough terrain and nimble, responsive handling for tight sections. With a low bottom bracket, slack head tube angle, and optimised fork offset, this bike keeps you centred for superior traction and control, whether you're bombing downhill or weaving through technical climbs.

Customise Your Ride. This bike offers unparalleled geo adjustability, making it the most personalizable trail bike on the market. With six unique geometry settings, you can fine-tune the head angle and bottom bracket height to match your riding style and terrain for the perfect blend of stability and clearance.

Engineered for Fun and Compliance. The M5 Alloy chassis is designed as a single, integrated unit, offering the right balance of stiffness and compliance for trail riding. The front and rear ends, along with the link, are engineered for optimal performance, ensuring that the frame is stiff but not overly rigid, giving you precise handling with a playful feel.

Wheel Size Options for Ultimate Versatility. All coil-sprung models come equipped with mixed wheels, but you can choose your ideal setup. With aftermarket shock links, you can switch between 29" wheels front and rear or opt for a 27.5" rear wheel for a more playful and responsive ride. No matter the configuration, the geometry remains unaffected, giving you full control over your ride.

Integrated SWAT Storage. The Stumpjumper 15 Alloy features SWAT storage in the downtube, a trail innovation pioneered by Specialized, allowing you to carry essential tools and gear seamlessly.

Built for Durability and Relentless Performance. Specialized full-suspension bikes are built to endure years of hard riding, offering unmatched durability and support. The lifetime replacement of suspension pivot bearings for the original owner ensures that your bike will remain trail-ready for years to come.

  • All-new M5 alloy frame with integrated SWAT door storage for on-trail essentials.
  • Roval Traverse alloy wheels paired with DT Swiss hubs for strength and reliability.

STUMPJUMPER, STUMPJUMPER EVO (STYLE SPECIFIC-SIZING) MY21 SIZING GUIDE

S-Sizing is based on what matters; rider size and style, not inseam. Six sizes, all with similar headtube lengths and standover allow you to choose the size that best suits your individual style. Smaller S-Size numbers are going to be more nimble, thanks to their shorter reach and front-centre measurement, while bigger S-Sizes deliver more stability and a roomier ride.

  • SIZE DOWN FOR MORE MANEUVERABILITY
  • SIZE UP FOR MORE STABILITY
