Frame and Geometry The frame is made of high-quality M5 aluminum, providing an optimal balance between stability and agility with 145 mm of rear travel. Thanks to the SWAT™ Door integration in the down tube, you can conveniently store essential items like tools or snacks directly within the frame. The geometry is adjustable, allowing you to modify the head angle and bottom bracket height with six individual settings to perfectly match your riding style and the terrain. Suspension System with GENIE Technology A standout feature is the FOX FLOAT Performance shock with innovative GENIE Shock Tech. This technology combines the linear spring rate of a steel spring with the progression of an air spring. As a result, it offers sensitive responsiveness at the beginning of the travel and sufficient bottom-out protection for hard hits. Together with the FOX FLOAT 36 Rhythm fork featuring 150 mm of travel, the bike delivers a confident riding experience on challenging trails. Drive System and Brakes The Stumpjumper 15 Comp Alloy is equipped with a Shimano SLX 12-speed drivetrain, ensuring precise and reliable gear shifts. For maximum control, it comes with TRP Trail EVO 4-piston disc brakes, featuring 203 mm rotors at the front and 180 mm at the rear (for frame size S4). Wheels and Tires The Specialized aluminum wheels with a 30 mm internal width are tubeless-ready and, in combination with the Butcher GRID TRAIL tires at the front and Eliminator GRID TRAIL tires at the rear, provide excellent grip and stability on various surfaces. Conclusion The Specialized Stumpjumper 15 Comp Alloy in Gloss Smoke/Cool Grey is a versatile trail bike that impresses with its thoughtful geometry, innovative damping technology, and high-quality components. It is ideal for riders looking for a bike that performs efficiently uphill and confidently downhill.
