Specialized has unveiled the Demo 11, a cutting-edge downhill bike developed over three years in collaboration with elite riders and World Cup-winning prototypes. This bike is engineered to deliver unparalleled speed, control, and predictability, enabling riders to tackle challenging terrains with confidence.
Frame and Suspension
The Demo 11 features a monocoque frame constructed from FACT 11m carbon, designed to withstand the rigorous demands of downhill racing. It offers 200 mm of rear travel, complemented by a high-pivot suspension system that enhances stability and control. The frame employs a mullet wheel setup, combining a 29-inch front wheel with a 27.5-inch rear wheel, optimizing handling and agility.
HighGear Drivetrain
A standout feature of the Demo 11 is the HighGear drivetrain, developed in partnership with SRAM. This innovative system utilizes an intermediate shaft to position the chainring higher, increasing ground clearance by 30 mm compared to previous models. This design also decouples drivetrain forces from the suspension, reducing pedal kickback and maintaining suspension performance under load. (blisterreview.com)
OBB Suspension System
The Over Bottom Bracket (OBB) suspension system is another key component of the Demo 11. This design allows for independent adjustment of braking behavior, wheel travel curve, and leverage ratio without compromise. The rear wheel moves approximately 13 millimeters backward in the first half of the suspension travel, providing a smooth ride over rough terrain. (velomotion.net)
Geometry and Adjustability
The Demo 11’s geometry is tailored for downhill racing, featuring a 62.5° head tube angle and size-specific rear centers to ensure balanced handling across frame sizes. Riders can fine-tune the bike’s fit and performance with adjustable headset cups that allow for a 6 mm change in front-center length and a flip chip that offers a 7 mm adjustment in bottom bracket height.
