THUDBUSTER G4 Short Travel
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. We are now proud to announce the latest evolution to that legacy with the all-new Thudbuster G4 ST.
The new Thudbuster G4 ST is superior to its predecessor in every way.
Building on Thudbuster’s proven parallel linkage technology we 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, we’re confident to say that 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 G4 ST includes 50mm of travel to significantly diminish shocks and impacts from broken pavement, cobblestones or any other mixed surfaces
