Innovative GENIE Technology Enhances Bump Force Management and Traction
Specialized has introduced the latest version of its well-known Stumpjumper series with the launch of the Stumpjumper 15. First released in 1981, the Stumpjumper has become a staple in the mountain bike community, and the new model brings exciting updates for trail riders.
At the heart of the Stumpjumper 15 is GENIE, a new air spring system designed by Specialized. This system uses two connected air chambers to provide a smoother ride and better manage bumps. This setup helps reduce traction loss by 57% compared to earlier models, making for a more stable and comfortable ride.
The Stumpjumper 15 offers adjustable settings to match different riding styles and terrains. Riders can choose between 29-inch wheels for faster rides and better stability or a mix with a 27.5-inch rear wheel for more nimble handling. These options do not affect the bike’s overall geometry, so it always performs well.
This bike allows for adjustments in six different ways, so riders can tweak the head angle and bottom bracket height to suit their preferences. This flexibility ensures that the bike can handle various trail conditions, from technical challenges to smoother paths.
With its new technology and customizable features, the Specialized Stumpjumper 15 aims to enhance the trail riding experience. It combines innovative design with flexible options, providing a great ride for both experienced bikers and newcomers to the sport.
