Designed specifically with the rigors of e-bikes and daily commuting in mind, the latest generation Thudbuster ST includes 50mm of travel to significantly diminish shocks and impacts from broken pavement, cobblestones or any other mixed surfaces.

Thudbuster ST is now able to support riders up to 330lbs (150kg) and incorporates a tool-free, interchangeable elastomer system to quickly and easily adjust the seat post for a variety of rider weights.

The Thudbuster Parallel Linkage 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. This results in a natural suspension feel without being overly active, and allows for more travel without compromising pedaling position.
