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 revolutionary M5 asymmetric 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 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.
