Specialized 21 Demo Expert

Pair an irrational appreciation for speed with the unmatched versatility of being able to run a traction-loving 29-inch front wheel and a snappy 27.5-inch rear, and you have the fastest, most capable Demo to date. The Demo Expert adds planted, confident control to the mix with an assist from RockShox’s BoXXer Select 29 fork featuring their DH DebonAir spring and a Super Deluxe Select Coil shock offering external rebound adjustment. Should your riding style or terrain require, the Demo's adjustable rear end means 29-inch rear wheel compatibiity is on deck, ready to deliver.

FEATURES

SRAM Code RS four-piston brakes front and rear give you the power to slow down with almost telepathic immediacy, while the Demo Expert’s suspension platform injects just the right amount of anti-rise into the kinematics equation in order to keep your weight low and centered, maximizing rear-wheel traction when you need it most.

• The Demo Expert M5 alloy frame is fully optimized to take advantage of the traction benefits of a 29-inch front wheel and the increased manueverability of a 27.5-inch rear wheel while maintaiining the ability to change your rear wheel size to 29-inch to suit different terrain and riding styles with an adjustable rear end that ensures chainstay length and bottom-bracket height stay dialed no matter the hoop size.
• The Rockshox Super Deluxe Select DH coil shock may be heavy on adjectives, but it’s even heavier on performance, offering external low speed compression and rebound adjustment while the Trunnion mount offers extra bushing overlap for increased durability.
