The Cane Creek Thudbuster G4 ST Suspension Seatpost utilizes a proven parallel linkage technology, while being completely re-designed for increased durability, a higher rider weight limit, 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 Thudbuster ST (short travel) has 50mm of travel to significantly diminish shocks and impacts from broken pavement, cobblestones or any other mixed surfaces.

Works perfectly. I’m an endurace trail cyclist and works well with my hardtail mtb. The extra soft insert (for raiders under 100pounds) is better than the soft insert even though my weight is 145.
