About this bike
Take on bigger lines, higher speeds, and better times with Specialized's Demo 8 I Carbon. Paired with 650b wheels, its responsive FACT Carbon 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 200mm of travel courtesy of RockShox's Boxxer RC fork and a custom Öhlins TTX shock that offer perfectly tunable travel to control even the biggest, fastest hits. Add in SRAM's DH-specific 7-speed drivetrain, Guide R discs, and burly Roval wheels wrapped in fat Specialized tires for max grip and unheard of speeds on every course. Plus, this downhill monster boasts a direct mount stem and thin Specialized flat pedals so you'll always have what you need to go bigger, higher, and faster.
