Technical Specifications
With multiple World Championships already to its name, the Demo 8 FSR II is the sport's fastest downhill machine. With 200mm of travel, a exclusive Öhlins TTX22M shock, and a RockShox Boxxer Team fork, it oozes premium downhill performance.
  • SRAM Guide RS DH brakes w/ metallic pads and reach adjust for premium stopping power
  • Legendary suspension tuners Öhlins make the ultimate bike and shock combo
  • RockShox Boxxer Team 650b, 200mm-travel fork is tuned for the world's gnarliest terrain
  • M5 alloy FSR frame w/ 200mm travel and new 650b S3 Geometry to handle gnarly downhill terrain
  • World Cup-proven Specialized Butcher DH front tire
  • SRAM X0 DH, PF30, carbon crankset w/ Gamut bashguard for elite DH performance
  • SRAM X0, 10-speed, short cage rear derailleur for crisp shifts and durability on rough terrain
  • Roval 650b rims w/ Hi Lo hubs are lightweight and durable for smooth handling at speed
  • Specialized Slaughter DH rear tire for fast-rolling performance on challenging terrain
  • The custom color—Rocket Red—is designed to naturally age over time. It will exhibit splashes of a dark rich color when exposed to prolonged direct sunlight. This finish is deliberate and therefore not covered under the traditional warranty policy.
