Due to multiple myeloma, two vertebrae in my back collapsed. I feared I would never ride again. After chemo, radiation, and a stem cell transplant treatment I eventually got back on a bike, but with a Thud Buster seat post. I’ve now been riding with it for five years. I cannot recommend this product highly enough for people with back issues.

Less impact, less pain, more riding.
Bike riding is one of the simplest ways to feel better—physically, mentally, and emotionally. For many riders, though, discomfort in the saddle turns something that should feel great into something that gets cut short.
No matter what kind of bike seat you have, rigid seatposts transmit harsh impacts and vibrations through the seat and into your body. These impacts can irritate the nerves and muscles in your low back, increasing pain, tightness, and fatigue. Thudbuster’s proven design soaks up harmful bumps, providing active cushion and support without being bouncy so you can ride as much as you’ve always wanted to.
Elastomer-Sprung
While other suspension posts use heavy, bouncy coil springs that waste pedaling energy, Thudbuster’s elastomer springs offer greater efficiency. Elastomer springs are dense blocks of rubber that are designed to absorb impact energy and rebound in a very smooth and controlled motion. No unwanted bouncing, and no pedal ‘bob.’ It’s the best solution for the most comfortable ride possible.
The Original
30 years of Parallel Linkage Technology
- Originally patented in 1995
- Allows for bump-absorption without changing the relative distance from seat to cranks
- Preserves a natural, easy pedaling motion
- No unwanted up/down bouncing
- Keeps seat level throughout movement
Which elastomers are included?
Thudbuster ST comes with 3 mid-range elastomer choices. Thudbuster LT comes with medium elastomer installed. Additional elastomers for both seatposts sold separately.
Which One is Right for Me?
Thudbuster LT offers the most cushion of any seatpost on the market. With over 3 inches of cushion, it’s for riders looking for max comfort.
Thudbuster ST has a shorter travel design that still offers a high level of adjustable cushioning, but in a package that can suit more riders. Thanks to the shorter linkage height, it’s usually the best choice for riders with very low seat heights or higher weight requirements (suitable for riders up to 330lbs/150kg).
