Product Details
Introducing the all-new Specialized Stumpjumper 15 Comp Alloy, designed to elevate your trail riding experience without compromise. This bike seamlessly blends the ability to conquer rugged terrain with the playful agility of a short-travel machine, making it perfect for any trail enthusiast. At the heart of its performance is the groundbreaking GENIE shock technology, which combines the plush grip of a coil spring with enhanced bottom-out prevention, allowing for independent tuning of mid-stroke and end-stroke support. The result? A ride that feels smooth and controlled, no matter the obstacles in your path.
With 145 mm of rear travel, the Stumpjumper 15 excels in bump force management, offering 16.3% better performance than traditional air shocks. This translates to improved traction—up to 57% more than the award-winning Stumpjumper EVO—keeping your wheels grounded and enhancing stability on the toughest trails. The bike's geometry is meticulously crafted to deliver big bike capability while maintaining nimbleness, thanks to a low bottom bracket and slack head tube angle that optimize your center of gravity for better control.
Personalization is key with the Stumpjumper 15, featuring six adjustable geometry settings that let you fine-tune performance to suit your style and the terrain ahead. Whether you prefer a more stable ride or want the responsiveness of a 27.5” rear wheel, the choice is yours without compromising geometry. Built with a robust M5 alloy frame and innovative SWAT door integration for convenient storage, this bike is equipped to handle the rigors of aggressive riding. With its FOX FLOAT Performance shock, Shimano SLX drivetrain, and TRP Trail EVO brakes, the Stumpjumper 15 is ready to take on any challenge while providing long-lasting support, including lifetime replacement of suspension pivot bearings to the original owner. Experience the future of trail riding with the Specialized Stumpjumper 15 Comp Alloy.
