Thudbuster ST Suspension Seatpost

Thudbuster ST Suspension Seatpost - Main image
$100 $199.99 In stock

Building on Thudbuster's proven parallel linkage technology, Cane Creek has completely re-designed the seatpost 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.


  • Forged aluminum post with 50mm of travel
  • Thudbuster Parallel Linkage technology compresses along the opposite path of a bump (down and rearward) to absorb the force, resulting in a natural suspension feel without being overly active, as well as more travel without compromising pedaling position
  • Single bolt fastening and angle adjustment design
  • Threaded, serviceable, hard anodized aluminum axles flanged PTFE bushings
  • Post can be tuned to rider weight through a simple elastomer change
  • Medium firm elastomer pre-installed from the factory. Extra Soft, Soft, Firm and Extra Firm elastomers sold separately
  • Maxium rider weight: 330lbs

Amelia Q. ★★★★★

The parallel linkage really soaks up potholes that used to rattle my teeth. I'm a heavier rider and the higher weight limit gave me confidence it would hold up. Two months in and the extra travel is still smooth as day one.

Andrew W. ★★★★★

Swapped this onto my commuter and the parallel linkage soaks up potholes way better than the stock post. Extra travel is noticeable on rough pavement, and the higher weight limit gives me peace of mind.

Brian I. ★★★★★

Rode a gravel century last weekend and my lower back felt fine afterward, which never happens. The extra travel on this thing is noticeable on washboard roads, and it hasn't developed any play after a few months of abuse.
