About this bike
The biggest, rootiest, and steepest DH courses just got a whole lot easier now that Specialized's Demo 8 I is on the scene. Paired with 650b wheels, its burly M5 aluminum frame boasts Specialized's legendary FSR suspension that smooths all trails, while its low center of gravity and low stand-over help you slash corners and rail rowdy sections. Keeping your run pinned are RockShox's World Cup-proven Boxxer RC and Fox's Van RC shock that offer 200mm of perfectly tunable travel to control even the biggest, fastest hits. Add in SRAM's Guide R discs and fat Specialized tires for max grip as well as burly Roval wheels for unheard of speeds out on every course. Plus, this downhill monster boasts a quick-shifting SRAM drivetrain with a Gamut chainguide so you'll always have the perfect gear.
