For over 20 years, Thudbuster has been the bicycle industry's standard in suspension seatposts by providing unsurpassed comfort and reliability to riders around the world. Cane Creek is now proud to announce the latest evolution to that legacy with the all-new Thudbuster ST G4. The new Thudbuster ST G4 is superior to its predecessor in every way.  Building on Thudbuster’s proven parallel linkage technology Cane Creek has completely re-designed the G4 for increased durability, a higher rider weight limit, and additional suspension travel, as well as ease of use with a tool-free elastomer and a single-bolt seat clamp design. By improving on this already legendary design, we’re confident the newest generation Thudbuster is the most advanced suspension seatpost ever made.

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


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.
