2020 Specialized Demo Race 29

The new Demo 29 comes roaring comes roaring out of the gates with multiple World Cup wins already under its belt. New chassis, new suspension kinematics, new geometry, and, yeah, new wheel size. Full gas. Full fast.

We’ve hung the Race model with the best gravity kit available.


The new Demo 29’s is blazing fast on tough tracks thanks to an axle path that reduces rear wheel hang up. And during moments when you do need to grab the brakes, the Demo 29 stays planted—with plenty of traction—we’ve added just the right amount of anti-rise to the mix.


When every second counts, every pedal stroke counts. The Demo 29’s new design allows for just the right amount of anti-squat. Or to put a finer point on it, you crank on the pedals and the Demo 29 rips forward instead of bobbing around uncontrollably and slowing you down.
