Specialized S-Works Demo 11 Frame

€0
Developed over three years with World Cup-winning prototypes and the fastest riders on the planet, Demo 11 had one objective: go faster everywhere.

This One Goes to 11.

FACT 11m carbon shrugs off World Cup hits and stays composed under maximum load. Integrated suspension architecture, adjustable geometry, and self-aligning features deliver predictable precision, control, and speed.

Self Aligning Chassis

Tension Keeps it Straight

Built for true downhill loads, Demo 11’s Self‑Aligning Chassis keeps the rear wheel tracking straight and predictably, even deep in the stroke, under maximum force.

Most designs push on the seatstays to drive the shock. That puts the system in compression, like trying to push a wagon straight, so under load it wanders off‑plane.
When loaded, Demo 11’s OBB creates a “pulling” force between the main pivot and rear axle. Like pulling on a wagon handle, the wheel stays aligned, delivering predictable handling throughout the travel.
The faster and rougher it gets, the more it matters: better in‑plane alignment, more predictability, fewer corrections, and more trust at speed.

Geometry: Speed By the Numbers

World Cup-refined geometry. Adjustable reach. Adjustable BB height for clearance or lower-and-faster. Three sizes with size-specific rear centers. Speed, engineered.

Adjustability: Front-Center

Front-center can be increased or decreased by 6mm, allowing riders to dial fit and balance based on track conditions, riding style, and personal preference, without compromising the bike’s fundamental stability.
Size-specific rear-centers ensure balanced handling across frame sizes, maintaining the same predictable behavior for every rider.

Adjustability: Bottom Bracket

Adjustable bottom bracket height: 7 mm drop from stock

FACT Carbon Construction

Optimized carbon layup, design, and construction deliver durability, precision handling, and reduced mass.

FACT: Built For World Cup Downhill

FACT (Functional Advanced Composite Technology) combines optimized carbon material, frame design, and construction methods to create a chassis purpose-built for downhill racing.
Every layer of carbon is placed to manage the specific forces a downhill frame experiences: massive impacts, high-speed compressions, and torsional loads from aggressive cornering.

The result is a frame that balances three critical performance attributes:

  • Durability to withstand World Cup-level impacts
  • Precision handling through tuned stiffness and alignment
  • Reduced mass for quicker direction changes and superior control
