If you don’t know the Demo, it’s time you got acquainted. Think of it as a two-wheeled, dirt-eating beast It just wants to go fast and this year, the Demo Expert 29 adds a new limb to the Demo family tree with an entirely new design that makes railing corners and those rock gardens easier than ever. It has a from the ground-up new frame, improved kinematics, better suspension under braking, bigger wheels, and all the latest fancy tech bits that make this the fastest Demo we’ve ever made.

Specialized have refined the Demo’s kinematics and suspension design. With one overriding goal—improve the bike’s ability to carry momentum, no matter how technical the terrain. More momentum equals more speed, after all. Beginning with altering the Demo’s axle path, making it more rear-ward in the initial stages of travel where sensitivity is most critical. The revised axle path reduces hang-up on square-edged bumps and that, in turn, transfers more energy to the suspension and less to you. Now, you finish a day of runs with less fatigue and more control.

Bigger wheels maintain momentum better than smaller ones—particularly over technical terrain. The Demo 29 weds 200 millimetres of suspension travel with bigger wheels in a package that’s crazy fast, yet still bike-park playful, also they improved the Demo’s suspension performance under braking and added a bit more anti-squat to improve its pedaling performance. Bottom line, the new Demo rolls faster through chunky terrain than its predecessor.

The Demo 29’s new shock linkage places weight low on the frame, giving the bike a lower centre of gravity and an even more confident and planted feel at speed. The new linkage is connected to a Trunnion-mount shock, which provides the Demo with the same 200 millimetres of rear suspension in a smaller (225x75mm) shock package. That smaller shock package helped  build a stiffer front down tube. And what’s more, the new Trunnion-mount shock features extra bushing overlap and adds ball bearings at the frame side of the shock, effectively boosting shock durability and making the suspension even smoother.

Specialized have fine-tuned the Demo’s geometry, as well. A relatively short (105mm) head tube keeps handlebar height in the right spot with the 29-inch wheels. We also compensated for the increased wheel size at the bottom bracket, keeping it at 350mm, in order to strike a balance between cornering stability and ground clearance. And lastly, the reach was increased by 20mm across the size range, starting at 425mm with the S2.

The devil is in the details, though, and the same rings true for the Demo 29, adding a bunch of little details that make it easier to live with. A newly designed, ribbed chainstay protector makes chain slap a thing of the past and nearly silences the drivetrain. A molded down tube protector, meanwhile, protects the frame from rocks while a co-molded rear fender protects the shock from mud and debris. Clearance for up to 29×2.6″ tyres allows for plenty of traction. And last, but not least, you’re going to find 148mm rear-spaced hubs, a threaded 83mm GXP bottom bracket, 200mm available post insertion, and internal and external cable routing options for rear brakes. Add it up and the Demo is as easy to work on as it is to find replacement parts for.

For the spec, its the perfect balance of durability, light weight, and reliability.

  • M5 alloy construction works in harmony with our Style-Specific DH Geometry to create the ultimate race machine. The design is compact in order increase maneuverability and responsiveness, while the 200mm of travel at the rear makes the bike capable of taking big hits in stride. And to fill out all of the details that make the difference on race day, we’ve included an ISCG ‘05 mount for chain guides and all the bits to make it easy to work on.
  • The RockShox Super Deluxe RC World Cup rear shock features a low-speed compression adjustment, external rebound adjustment, and a Trunnion mount that makes for a smaller shock envelope and increased durability.
  • RockShox BoXXer RC 29 fork is nothing short of legendary. With 200mm of travel, a DebonAir spring for maximum efficiency, and adjustable low-speed compression, it’s easy to see why it’s such a fan favorite for gravity fiends
