For over 20 years, the Thudbuster has been the standard in the bicycle industry for suspension seat posts, providing riders around the world with unmatched comfort and reliability. We are proud to announce the latest development in this legacy with the brand new Thudbuster ST. The new Thudbuster ST surpasses its predecessor in every way. Building on the proven parallel linkage technology of the Thudbuster, we have completely redesigned the seat post for increased durability, higher rider weight capacity, additional travel, and easy operation with tool-free elastomer replacement and a screw-in seat clamp design. We are confident that the latest generation of the Thudbuster is the most advanced suspension seat post ever made.
