For over 20 years, Thudbuster has been the bicycle industry standard in suspension seatposts by providing unequaled comfort and reliability to riders around the world.

Now Cane Creek announce the latest evolution to that legacy with the all-new Thudbuster ST. The new Thudbuster ST is superior to its predecessor in every way. Building on Thudbuster’s proven parallel linkage technology they have completely re-designed the seatpost for increased durability, a higher rider weight limit, and additional suspension travel, as well as ease of use through tool-free elastomer change and a single-bolt seat clamp design. By improving on this already legendary design, they're confident to say that the newest generation Thudbuster is the most advanced suspension seatpost ever made.


The All-New Thudbuster 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. Installing and adjusting your seat on the new Thudbuster is easier than ever as well with a single bolt design that secures the seat with a few turns of a standard hex tool.
