Specialized 2021 Stumpjumper Alloy
The Stumpjumper Alloy brings all of the new, lust-worthy features of the Stumpjumper-like new suspension kinematics and geometry-into a full-alloy package that's both lightweight and extremely durable. Top it off with a no-fuss SRAM SX 12-speed groupset and you have the perfect ride for your next trail adventure.
- THE TRAIL BENCHMARK
When we set out to design the all-new Stumpjumper, we pursued some hefty goals. We went after the lightest-possible weight that sacrifices nothing to durability, a stiff chassis that corners on rails, and a geometry that everyone can enjoy, all with the best suspension kinematics we know how to design. Turns out, you can have your cake and eat it too with the new Stumpjumper.
- TRAIL-TAMING TRAVEL
All the travel in the world is useless without the proper kinematics, which is why we kept it at the forefront of the new Stumpjumper design. With the learnings from the suspension design on the Enduro, and over 1,000 hours of field and suspension lab development, we’ve greatly improved the pedaling performance, all while creating the capable, efficient, lively feelings that you long for. We increased anti-squat, so the suspension better-resists pedal bob and then, we further-improved bump performance on square-edge hits. Bottom line? The all-new Stumpjumper descends with complete control yet climbs with ease.
- PROGRESSIVE GEOMETRY
The S-Sizing geometry of the new Stumpjumper hits the progressive sweet spot. Long, low, slack, a short offset fork, a steeper seat tube angle—they’re all the talk of the town because they make your ride better. With Flip Chip adjustability you’re able to further fine-tune your fit, ensuring that your new Stumpjumper performs flawlessly on whatever terrain you choose.
