Meet the adrenaline-pumping beast of the mountains – the Specialized Demo Expert Downhill Mountain Bike (2023)! This bike is all about speed and versatility, and it's ready to take your downhill adventures to the next level. Imagine combining a borderline crazy love for speed with the unparalleled flexibility of running a 29-inch front wheel and a snappy 27.5-inch rear wheel. The result? The fastest and most capable Demo version ever created!
But speed isn't everything. The Demo Expert knows the importance of control, and it gets an extra dose of confidence from RockShox's BoXXer Select 29 fork, complete with the DH DebonAir spring. And as if that's not enough, there's also the Super Deluxe Select Coil shock with external rebound adjustment to keep you in command on the gnarliest terrains.
 The Demo Expert has it all figured out – the perfect balance of anti-rise in its suspension platform keeps your weight low and centered, granting maximum rear-wheel traction exactly when you need it the most. Prepare to conquer every twist, turn, and obstacle with finesse and style.
So, if you're looking for a mountain bike that's not just fast but also FUN and built for domination, the Specialized Demo Expert is your ticket to a wild, unforgettable ride.Â
Features:
- 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 maneuverability of a 27.5-inch rear wheel while maintaining 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.
