The new Thudbuster G4 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.
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
