The Specialized Stumpjumper Alloy Full Suspension Mountain Bike integrates advanced suspension kinematics and progressive geometry into a lightweight yet durable full-alloy frame. Equipped with a straightforward SRAM SX 12-speed groupset, the Stumpjumper Alloy is your gateway to trail adventures.
In designing the new Stumpjumper, Specialized set ambitious goals: it had to excel on any trail for every rider. To achieve this, they focused on significant weight reduction without compromising durability, creating a stiff and responsive chassis that remains light and lively. The geometry enhances every rider's experience, and the suspension kinematics are among the best they've ever designed. With the new Stumpjumper, you can indeed have it all.
Specialized fine-tuned the kinematics of the Stumpjumper suspension for optimal all-around performance within a 130mm travel package. Through extensive suspension lab development and field testing, they crafted a refined mid-travel bike that handles big terrain like a beast, rides smoothly everywhere, and climbs with ease.
The S-Sizing geometry of the new Stumpjumper hits the progressive sweet spot. It features a long, low, and slack design, a short offset fork, and a steeper seat tube angle. These elements combine to make your ride more stable, more agile, and more comfortable when climbing. With FlipChip adjustability, you can fine-tune your fit, ensuring flawless performance on any terrain.
Rider-First Engineered™ frames use a size-specific approach to ensure consistent handling and flawless performance across all frame sizes. Whether you're a jump-happy rider on an S1 or a downhill enthusiast on an S6, you'll experience sharp cornering and balanced stiffness at the lightest possible weight. By light, they mean really light: 2,250g (S-Works, S-3 size, with rear shock).
