Product Details

Key Features:
M5 Alloy Chassis: 100% Redesigned durable alloy chassis.
Wheel Size: S1-S2: Mixed Wheel (29" Front / 27.5" Rear) / S3-S6: 29"
Travel: Travel - 150mm Front / 145mm Rear
Specialized GENIE Shock Technology: Patent-pending air spring technology provides the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable platform for a playful feel. Extensive field testing proves that Stumpjumper 15 with GENIE delivers 57% better traction than a standard air-sprung shock because GENIE technology gives you supple, coil-like performance, which keeps the wheel in contact with the ground more than a typical air spring would.
Honed Geometry: This bike's geometry delivers big bike capability when you need it, a nimble feel in tight sections, and lively, efficient climbing manners. The generous cockpit centers you on the bike, optimizing traction and corner control. The low bottom bracket, slack head tube angle, and optimized fork offset keep things stable in the rough.
Adjustable Geometry: The Stumpjumper 15 seamlessly integrates benchmark geo adjustability, making it the most personalizable trail bike ever. Six distinct geometry settings allow you to hone performance for any style, any terrain. Head angle and bottom bracket height can be fine-tuned for stability or clearance.
Wheel Choice: With aftermarket shock links, you can choose between big wheels front and rear or mix things up with a 27.5” rear for a more responsive and playful ride. No matter what you choose, geometry is unaffected.
SWAT 4.0: SWAT 4.0 on Stumpjumper 15 elevates downtube storage, an innovation Specialized pioneered. It’s the smoothest operating, most weather-resistant, flush-mounted system ever.
