Thudbuster Long Travel

Thudbuster Long Travel


Thudbuster is the most effective and versatile suspension seatpost on the market. Its patented, parallel linkage technology delivers a clear advantage in comfort and control. Performance makes this seatpost the perfect add-on for a wide variety of riders or bikes.

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 forward 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.
