SPECIALIZED STUMPJUMPER 15 FOX COIL ALLOY

The SPECIALIZED Stumpjumper 15 Alloy is a trail bike engineered to tackle any path without compromise. It flows over obstacles with the fluidity of a long-travel bike, yet maintains the precision, responsiveness, and efficiency typical of lighter, more agile bikes. It is a modern, versatile, and fully customizable platform, designed to adapt to every riding style.

The refined kinematics represent the meeting point between the previous Stumpjumper and EVO, offering excellent impact force management and improved pedaling efficiency thanks to anti-squat optimization. The result is a bike capable of climbing decisively and descending with great confidence.

The adjustable geometry allows for six different configurations, enabling the adaptation of the steering angle and bottom bracket height based on terrain and rider preference. The low bottom bracket, slack head angle, and optimized fork offset guarantee stability on technical sections, agility in tight passages, and effective climbing performance.

The M5 Alloy frame is designed to offer the right balance between stiffness and flexibility, ensuring precise handling and comfort on the most demanding trails. The SWAT™ compartment integrated into the downtube allows for carrying essential items directly on the bike, keeping the setup clean and functional.

Compatibility with differentiated or uniform wheel configurations allows you to choose between a mullet setup for a more playful ride or a dual 29” setup for greater stability and speed, without altering the frame geometry.
