A World Cup-developed downhill race chassis built to find speed when the track gets serious.
The S-Works Demo 11 Frameset is Specialized’s no-compromise downhill platform, developed over three years with World Cup-winning prototypes and elite racers. Its FACT 11m carbon race chassis, OBB linkage and high-pivot drivetrain are designed to deliver predictable control, composure and speed from the start gate to the finish line.
Built to Go Faster Everywhere
Demo 11 is designed around the confidence to commit. The chassis delivers a calm, controlled feel through rough sections so you can settle into a rhythm sooner, hold faster lines and maintain speed when the track becomes steep, loose and unpredictable.
OBB Linkage and 200 mm of Travel
The OBB linkage works with the included RockShox Vivid Coil Ultimate DH shock to provide 200 mm of rear travel. This gives the bike the sensitivity and support needed for repeated high-speed impacts, big compressions and demanding downhill tracks.
High-Pivot Drivetrain
The HighGear drivetrain design provides an additional 30 mm of ground clearance. This helps reduce drivetrain exposure in rock gardens and deep ruts while supporting the Demo’s composed, race-focused handling.
Custom Race Build Foundation
The frameset format lets you choose the fork, wheelset, brakes, drivetrain and cockpit to suit your race programme and preferred setup. It is a premium starting point for riders who want every part of their downhill bike chosen with purpose.
