The Specialized Stumpjumper 15 S-Works Frame is a revolutionary trail bike frame that obliterates the trade-offs between big travel and short travel bikes. Featuring the groundbreaking GENIE Shock Technology, this frame delivers the benefits of a big travel bike and the benefits of a short travel bike in one package, allowing you to personalize it to your riding style and terrain.

Key Features:
  • GENIE Shock Technology: Combines the control-enhancing linear spring rate of a coil spring with the progressive spring rate of an air spring, providing the best of both worlds with improved traction, bottom-out prevention, and tunability.
  • Ultimate Control: Provides measurably better traction than the award-winning Stumpjumper EVO, keeping the wheel in contact with the ground for greater control.
  • Unmatched Personalization: Offers six-way geometry adjustment, mixed wheel size compatibility, and a tunable spring curve to perfectly match your riding preferences.
  • Lightweight and Durable: Features a FACT 11m carbon chassis, rear-end, and link for exceptional strength and low weight.
  • Premium Suspension: Equipped with a FOX FLOAT Factory suspension tuned for Ride Dynamics, with a highly adjustable 2-position open and firm mode, and a 3-position open mode compression adjuster.
  • Lifetime Bearing Replacement: Backed by Specialized's unbeatable lifetime, no-questions-asked bearing replacement policy.
