Specialized Stumpjumper 15 Alloy Mountain Bike: Redefining Trail Performance
The Specialized Stumpjumper 15 Alloy Mountain Bike is designed to eliminate every compromise in the trail riding world. Want to tackle big bumps like a long-travel bike? Done. Need short-travel control, playfulness, and efficiency? Absolutely. Looking for ultimate personalisation to tailor it to your riding style? You’ve got it.
Breakthrough Performance with GENIE Shock Technology. The Stumpjumper 15 Alloy introduces GENIE Shock Technology, delivering a playful, poppy ride with a bottomless downhill feel. This patent-pending air spring innovation combines the grip and traction of a coil with the support and tunability of an air spring, giving you the best of both worlds.
Unrivaled Traction and Control. The GENIE technology offers 57% better traction than standard air-sprung shocks, keeping your wheels grounded for superior grip. This enhanced traction results from its coil-like performance, ensuring your bike remains connected to the trail for maximum control. You'll feel the difference with smoother handling and more confident descents.
Say Goodbye to Bottom-Outs. GENIE’s two-stage rising rate reduces bottom-outs by 39% compared to typical air springs. With better bottom-out prevention, you'll have smoother rides over big hits, benefiting from GENIE’s superior shock performance in the last 30% of the stroke. Experience plush performance without sacrificing control on aggressive terrain.
Optimised Geometry for Any Trail. The Stumpjumper 15 Alloy’s geometry blends big bike capability with nimbleness in tight sections, offering stable climbing and confident cornering. A low bottom bracket, slack head tube angle, and optimized fork offset give you unmatched control in rough sections while maintaining agility.
Fully Adjustable for Your Ride. Personalise your ride like never before with six geometry settings that allow you to fine-tune the head angle and bottom bracket height. Whether you're prioritising stability or ground clearance, the Stumpjumper 15 Alloy adapts to any trail, making it the most customisable trail bike ever.
Choice of Wheel Configurations. The Stumpjumper 15 Alloy offers flexible wheel configurations. With Specialized's aftermarket shock links, you can ride with 29-inch wheels front and rear or opt for a 27.5-inch rear wheel for a more playful and responsive feel. No matter your choice, the geometry remains unaffected for optimal performance.
Innovative SWAT Storage. Specialized pioneered the SWAT storage system, and the Stumpjumper 15 Alloy takes it to the next level. Integrated downtube storage lets you carry essential gear on the trail without extra packs or clutter.
Built for Durability and Backed for Life. The Stumpjumper 15 Alloy is designed for relentless trail riding, offering a lifetime of support with no-questions-asked replacement of suspension pivot bearings for the original owner. This durability is backed by Specialized’s industry-leading support and warranty, ensuring your bike stays trail-ready for years.
