2025 Specialized Stumpjumper 15 COMP Carbon Mountain Bike
The Specialized Stumpjumper 15 COMP Carbon is built for riders who want a perfectly balanced trail bike that climbs efficiently, descends confidently, and adapts to a wide variety of terrain. Designed around Specialized’s modern trail geometry, this bike delivers stability, agility, and control without sacrificing fun.
With its lightweight FACT 11m carbon frame, integrated SWAT 4.0 storage, and proven suspension platform, the Stumpjumper 15 COMP is ready for everything from long all-mountain days to technical singletrack sessions.
Confident Suspension Performance
The front end is handled by the FOX FLOAT 36 Rhythm fork with GRIP damper, offering excellent stiffness and smooth damping for aggressive trail riding. At the rear, the FOX FLOAT Performance shock with GENIE technology delivers controlled small-bump sensitivity and progressive support through the travel.
Modern Drivetrain & Reliable Braking
The bike is powered by the SRAM S1000 Eagle Transmission, a fully electronic 12-speed drivetrain that shifts precisely under load. For braking, SRAM Maven Bronze hydraulic disc brakes provide consistent stopping power and modulation on steep, demanding descents.
