SPECIALIZED STUMPJUMPER ALLOY 2022

The Stumpjumper Alloy brings all the desirable features of the new Stumpjumper—such as updated suspension kinematics and modern geometry—onto a fully aluminum frame, lightweight yet extremely durable. It is completed with a simple and effective 12-speed SRAM SX Eagle groupset, perfect for your next trail adventures.

SUSPENSIONS READY TO TAME THE TRAILS
All the travel in the world is useless without a well-designed kinematic: that's why it was a priority in the development of the new Stumpjumper. Thanks to the experience gained from designing the Enduro suspension and OLTRE 1,000 hours of field and lab testing, we have significantly improved pedaling performance, while maintaining the sense of efficiency, responsiveness, and control that every rider desires. The increased anti-squat reduces sag during pedaling, while the response to sharp impacts has been further optimized. The result? A bike that descends safely and tackles climbs with ease.

PROGRESSIVE GEOMETRY
The S-Sizing geometry of the new Stumpjumper achieves the perfect progressive balance. Long, low, and open frame, reduced offset fork, more vertical seat tube: all elements that improve ride quality. Additionally, thanks to the Flip Chip system, you can further adjust the bike's setup to best suit your style and routes.
