Demo 11
Highlights
- Built from FACT 11m carbon, the Demo 11 frame is made to survive World Cup punishment, and stay razor-precise under maximum load
- HighGear Drivetrain is a patent‑pending drivetrain system that raises ground clearance by 30mm and removes unwanted drivetrain influence from the suspension
- The OBB (Over Bottom Bracket) suspension linkage system delivers predictable control, remains composed when braking hardest, reduces rider input, and saves energy deep into long downhill runs
- With the Demo 11’s OBB system, the shock is driven through the chainstays, pulling between the main pivot and rear axle, which means the rear wheel stays aligned in‑plane, so the bike stays calm and predictable through the travel
- Adjustable front-center +/- 6mm per frame size
- Size-specific rear centers
- Adjustable bottom bracket height of 7mm via flip chip
Description
One Word: Speed. Demo 11 was developed over three years with multiple World Cup-winning prototypes with the fastest riders on the planet to realize a single objective: Go faster everywhere. Not through hype. Not through excess. Through control, predictability, and race-proven innovations that unlock previously impossible lines. This is downhill
speed through trust.
Demo 11’s suspension performance is built around two distinct systems working together, each engineered to address a specific challenge in downhill racing. Together, HighGear and OBB (Over Bottom Bracket) linkage deliver a fully active, fully independent suspension system that yields superior bump force management, stays calm under extreme load, virtually eliminates pedal feedback, and allows riders to carry more speed through any terrain with complete control.
HighGear is a patent‑pending drivetrain system that raises ground clearance by 30mm and removes unwanted drivetrain influence from the suspension. It enables an optimized axle path and fully active suspension performance—with virtually no pedal feedback. Developed with SRAM for no-compromise reliability.
A compact chainring mounted to the crank spindle drives a jackshaft. The final-drive ring is mounted to the jackshaft and drives the rear wheel. The strategic location of the final drive ring ensures that above chainstay chain length remains constant, so chain forces are independent from rear suspension, and rear suspension is independent from pedal forces.
The OBB (Over Bottom Bracket) suspension linkage system provides the tuning freedom behind Demo 11’s ride quality. Its unique linkage allows engineers to independently tune axle path, leverage rate, and braking behavior rather than compromising one attribute to achieve another.This decoupling enables precise control of bump force management while keeping the suspension fully active, even under hard braking. The result is a bike that delivers predictable control, remains composed when braking hardest, reduces rider input, and saves energy deep into long downhill runs.
