Thudbuster ST

Suspension Seatpost

The latest generation Thudbuster 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.

Accessibility

Thudbuster ST 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.

Parallel Linkage Design

The Thudbuster Parallel Linkage technology stays in the direct path of the natural travel of the rear wheel. As a bump lifts the back of a bicycle, the rear wheel pushes up and forward into the rider. The Thudbuster works by compressing along the exact opposite path — down and rearward — absorbing force at the same rate. This results in a natural suspension feel without being overly active, and allows for more travel without compromising pedaling position.

Even at tightened specs seat manages to to make a loud "click" sound and then will tilt downward at the nose of saddle while on rocky downhills. I have the rails set perfectly in middle so I feel this is due to a bad clamping design. Very disappointed. I am someone that owns multiple 110 headsets, eeSilk stem/bar, and another thudbuster (lt)...

I loved my previous LT (long travel) Thudbuster, but in my current bike the height of the LT would have made my saddle too high. The ST (short travel) would fit my bike and I thought it's claimed two inches of travel would be fine. The St is light, and very high quality, but I found it to have only one inch of travel, which is just not enough for me. I bought a competitors two inch spring seat post that does have two inches of travel and it's almost as good as my LT Thudbuster on my other bike.
