THE SCIENCE BEHIND THUDBUSTER
WORKING IN THE DIRECT PATH OF THE NATURAL TRAVEL OF THE REAR WHEEL.
The Thudbuster technology stays in the direct path of the natural travel of the rear wheel. As a bump lifts the back of a bicycle, the rear wheel pushes up and foward into the rider. The Thudbuster works by compressing along the exact opposite path -- down and rearward -- absorbing force at the same rate: The net movement of the saddle is zero. Fully active elastomers provide approximately 3 inches (76mm, Long Travel) or 1.3 inches (33mm, Short Travel) of customizable suspension.
