Specialized Stumpjumper Alloy Mountain Bike – 2024

SPECIALIZED STUMPJUMPER ALLOY MOUNTAIN BIKE – 2024

The Stumpjumper Alloy brings all-new suspension kinematics and progressive geometry into a full-alloy package that’s both lightweight and extremely durable. Outfitted with a no-fuss SRAM SX 12-speed groupset, the Stumpjumper Alloy is your all-access pass for trail adventure.

FEATURES

• PROGRESSIVE GEOMETRY — The S-Sizing geometry of the new Stumpjumper hits the progressive sweet spot. It’s long, low and slack, with a short offset fork and a steeper seat tube angle. These numbers combine to make your ride more stable, more carvealicious, more comfortable climbing, more better everywhere. With FlipChip adjustability you’re able to further fine-tune your fit, ensuring that your new Stumpjumper performs flawlessly on whatever terrain you choose.
• THE SWEETEST 130MM OF TRAVEL YOU’LL EVER RIDE — Specialized massaged the kinematics of the Stumpjumper suspension to bring out the very best all-round performance possible in a 130mm package. Countless hours of suspension lab development and field testing created a refined mid-travel ripper that eats big terrain like a gravity fed beast, handles like a dream everywhere, and climbs like it has a motor.
• RIDER-FIRST ENGINEERED — Rider-First Engineered frames use a size-specific approach to ride characteristics that ensures benchmark handling and flawless performance, regardless of frame or rider size. Whether you’re a jump-happy grom riding an S1, or a DH-fiend giant in need of the lengthy S6, you’ll experience the same ride traits – rail-sharp cornering and balanced front and rear stiffness – at the lightest-possible weight, And by light, they mean real light: 2,250 grams (S-Works, S-3 size, with rear shock).
• THE TRAIL BENCHMARK — When Specialized set out to design the all-new Stumpjumper, they pursued some hefty goals. It had to excel on any kind of trail, for every style of rider. To achieve that, Specialized went after serious weight reduction without sacrificing durability, a stiff, responsive chassis that still rides light and lively, geometry that improves everyone’s riding, and the best suspension kinematics they know how to design. Turns out, you can have your cake and eat it too with the new Stumpjumper.
