S-Works Stumpjumper 15 - SRAM XX AXS, FOX Factory

The Stumpjumper 15 is designed to eliminate trade-offs in trail riding, delivering big bike capability for bumps while maintaining short-travel control, playfulness, and efficiency. The bike features six-way geometry adjustment and personalization options to suit any rider's preferences. The breakthrough innovation is GENIE Shock Technology, a patent-pending air spring system that combines the feel and control of a coil spring with the progressive spring rate of an air spring. This dual-stage design provides better bottom-out prevention than standard air springs while maintaining a tunable platform for a playful ride. GENIE delivers measurably superior performance compared to traditional air-sprung shocks. The Stumpjumper 15 manages bump forces 16.3% better than conventional air springs, provides 57% better traction by keeping the wheel in contact with the ground longer, and experiences 39% fewer bottom-outs during big hits. The technology achieves this through a linear spring rate in the bump zone combined with a pronounced rising rate in the final 30% of the stroke. The geometry is carefully honed to deliver big bike capability when needed, nimble handling in tight sections, and efficient climbing performance. A generous cockpit centers the rider for optimal traction and corner control, while the low bottom bracket, slack head tube angle, and optimized fork offset provide stability in rough terrain. The Stumpjumper 15 offers extensive personalization through six distinct geometry settings that can be adjusted for any riding style or terrain. Head angle and bottom bracket height can be fine-tuned independently for stability or clearance. Wheel configuration is flexible—you can run big wheels front and rear or mix a 27.5" rear wheel for a more responsive and playful ride, with geometry remaining unaffected. Storage is integrated through SWAT 4.0, a flush-mounted downtube storage system that provides smooth operation and weather resistance. The bike is built on a lightweight FACT 11m carbon chassis with a carbon rear-end and link, paired with the lightest high-performance Roval Traverse SL II wheels and DT Swiss 240 hubs. The drivetrain features the strong and precise SRAM XX Eagle T-Type AXS system, while braking comes from SRAM Maven Ultimate 4-piston hydraulic disc brakes. The fork is a supportive FOX FLOAT 36 Factory with GRIP X2 damper, and the rear shock is a Ride Dynamics tuned FOX FLOAT Factory with Specialized GENIE Shock Tech. A RockShox Reverb AXS dropper post provides smooth height adjustment. Specialized backs the bike with a lifetime, no-questions-asked replacement of suspension pivot bearings to the original owner, reflecting the durability and support commitment for this relentless trail machine.
